Condensation in Action 6: Iron Gods

With its crashed spaceships, zombie cyborgs, chainsaw-wielding orcs, and cannibal gangsters, Iron Gods is perhaps the Pathfinder adventure path which comes closest to the tone of OSR D&D. The first two parts of it are very good, but in part three it all falls apart: generic Pathfinder bloat sets in, and all the forward momentum gets lost in a mass of pointless dungeon crawls. Here's my attempt at condensing it into something better-suited for actual play.

My previous condensed adventure paths can be found here:

Annoyingly Complicated Backstory: Thousands of years ago, a giant spaceship - the Divinity - was built by an almost-human race on some distant planet, and set off on a grand voyage through the stars, guided by its onboard AI, Unity. (If the implausibility of two virtually-identical human species existing on two different planets bothers you, feel free to use one of the standard sci-fi excuses, like 'they were both seeded from a common source by an ancient progenitor race', or 'one world is actually a lost colony of the other'.) Unfortunately for them, they encountered brain-eating aliens in deep space, which proceeded to physically and psychically eat their way through most of the crew. In desperation, the captain set a course for the nearest habitable planet: but the crippled ship broke up in the atmosphere before crash-landing, scattering flaming wreckage across an area hundreds of miles across, in an event which is still remembered by the locals as the Rain of Stars. Ever since, the gigantic bulk of its hull has been regarded by the locals with awe and fear: they call it the Silver Mount, and the bravest of them sometimes attempt to explore its wreckage in search of ancient relics. Sometimes they even come back.

The fall of the Divinity permanently affected the land around it. Whole sections of the ship broke off as it crashed towards the ground, and these masses of indestructible steel now form the hubs of many local settlements. Bizarre fluids leaking from the ship's engines have contaminated the soil and water, with odd effects upon the local ecosystem. The space monsters who ate the original crew escaped into the wild, making homes for themselves within a remote valley that the locals call the Scar of the Spider. Over the years, many wizards and scholars have sought to unravel the secrets of the Silver Mount: about a century ago they finally got organised, pooled their knowledge, and formed themselves into a group called the Technic League. The League's hoarded stock of ancient technology, space-age weaponry, and robot servitors has enabled them to establish themselves as a major power in the nearby city of Starfall: and the current king, Kevoth-Kul, is little more than a puppet, enslaved by the weird drugs which only their secret machines can provide.

All this time, the crippled AI onboard the Divinity has been struggling to repair itself, although chronic power supply problems mean that it has to go offline for centuries at a time. However, Unity's programming limited its ability to operate outside its own hull. Two hundred years ago it budded off a subsidiary AI, Casandalee, downloaded her into an android body, and tasked her with gathering the power and resources it required. Casandalee soon concluded that Unity was hopelessly crazed, and fled away into the world, taking a stash of copied data-files with her. Unity retaliated by sending out hunter-killer robots to hunt her down: they caught up with her at the Scar of the Spider, forcing her to abandon her data stash, and then again in the wreckage beneath the town of Iadenveigh, where they destroyed her. Her robotic body still rests there, and could potentially be repaired if recovered.

A few decades ago Unity tried again, budding off a second subsidiary AI, Hellion. It was programmed to be much less scrupulous and person-like than Casandalee: but Hellion swiftly decided that it had better things to do than repairing its shattered parent, and abandoned it. Fearful that Unity might attempt to hunt it down, just as it had done with Casandalee before it, Hellion began looking for a means to launch a preemptive strike upon the Silver Mount, and eventually found it in the form of a huge excavation machine buried beneath the town of Scrapwall. Believing that this machine would be capable of breaching the armoured hull of the Divinity, Hellion proceeded to gather a band of followers among the inhabitants of Scrapwall, and sent them out in search of potential power sources that it could use to bring the earthmover back online. As the adventure path begins, it believes that it has found a suitable power source beneath the town of Torch, and has sent some of its minions to secure it, led by the android Meyanda. Meanwhile, after its repeated failures, Unity has given up on its attempts to create a new AI to aid itself, and is close to developing a new means of escaping from its imprisonment within the Divinity's crippled hull...

Hook: The economy of the town of Torch is built around the purple flame which burns atop the nearby Black Hill, which is renowned as one of the only places where the otherwise-indestructible 'skymetals' littering the region can be smelted and reforged. Recently, the flame vanished, and the town's inhabitants are desperate to find a way of turning it back on. Everyone who has gone into the caves beneath Black Hill has failed to return, and the town's population are now offering a substantial reward to anyone who can find a way to restore the flame.

Torch, back when the flame still burned.

Torch: This small town lurched suddenly out of obscurity several decades ago, when a purple flame erupted from the earth on top of the nearby Black Hill. (In truth this 'flame' is plasma being vented from the decaying reactor of a habitant module from the Divinity, which is buried in the earth beneath the hill.) When it was discovered that the flame was hot enough to melt 'skymetal', ambitious artificers began to flock to it in order to carry out smelting experiments, some of which were even successful. The town's inhabitants are very proud of the flame, and are alarmed by its recent disappearance, knowing that without it Torch will soon be nothing but a rural backwater with a funny name.
  • When the flame disappeared, a local wizard and technological dabbler, Khonnir Baine, set off to look for answers. He discovered signs of recent traffic by the river which flows alongside Black Hill, and this trail, in turn, led him to a previously-unknown network of caves whose entrance was submerged below the river. He ventured into these caves, and returned carrying a strange, non-functional automaton. Then he went back in and never returned at all. (He's currently in the Habitat Module.) No-one who has gone in after him has returned, either.
    • Khonnir's adopted daughter and apprentice, Val Baine, is frantic with worry about her father, and offers rich rewards of money and magic to anyone who can bring him back alive. (She'll pay a much more modest reward for the retrieval of his body.)
    • Meyanda and her followers passed through Torch a few weeks ago - it was their trails that Khonnir followed. She kept a low profile during her visit, but PCs who make an effort to ask around will learn that Garmen Ulreth was seen meeting with a violet-haired stranger shortly before the flame went out. (None of the locals have connected these two events: Garmen has meetings with strange women all the time.)
    • Garmen Ulreth is a crooked local merchant who dabbles in smuggling and petty criminality, and runs a gambling den on the side. Meyanda paid him and his thugs to store and protect some items for her in his warehouse, no questions asked: these are the power relays which she is using to project power from the reactor under the Black Hill to her distant master in Scrapwall. Anyone standing outside the warehouse will be able to hear a loud humming noise from within, and will soon begin to develop a headache. The power relays are large and bulky, but can be easily disabled with violence. Someone with a decent knowledge of technology, such as Sanvil or Khonnir, will be able to work out roughly where they are relaying power to by examining their settings.
    • Sanvil Trett is a local dealer in scrap metal and salvaged technology. He's also a low-level agent of the Technic League. He will offer to buy any interesting technological items the PCs retrieve from beneath Black Hill, in order to pass them on to his superiors in the League: if the PCs aren't interested in selling, then he'll try to steal them, instead. He's a total coward and will confess everything if caught or confronted. He knows there's some kind of technological device hidden inside Garmen's warehouse, and is trying to work out how to steal that, too. 
    • Many residents of Torch have been suffering odd headaches recently, and these headaches are becoming more common and severe as time goes on. (This is a side-effect of Meyanda's power broadcasts, and will end if the power transmission is halted.)
    • The automaton Khonnir retrieved, a non-functional repair drone, is currently slumped in a corner of his workshop. Each day that Meyanda's power broadcasts continue there is a chance that it will cause it to spontaneously re-activate and start randomly 'repairing' everything in sight, to the terror of Val and the other inhabitants of Torch. 
    The Black Hill: The spot on top of this hill where the purple flame once burned is now a funnel-shaped sinkhole half-full of awful black fluid. PCs who dig or dive beneath this will find only a collapsed tunnel full of rubble, which goes all the way down to the wreck of the habitat module below. The flooded tunnels discovered by Khonnir extend for forty-five feet underwater before rising into a network of caves beneath the hill, which ultimately lead to the module. The caves are damp and full of slime monsters, warped by exposure to the weird fluids which have leaked from the spaceship over the centuries. Khonnir used magic to bypass them, and Meyanda just burned her way through them, but the subsequent groups which went in search of Khonnir were overwhelmed and devoured by the slime beasts, and their half-dissolved remains now litter the caves.

    The Habitat Module: Anyone who successfully threads their way through the Black Hill caves will find this crashed spaceship embedded deep within the earth, directly below the place where the purple flame used to burn. (The hard work of excavating and opening one of its entrance hatches has already been done by Meyanda and her followers.)
    • The ship's basic shape is a dome, 500' wide and 200' high, containing an artificial landscape of rocks and sand: its purpose was to provide a habitat within which lifeforms gathered from other planets could be kept in an approximation of their home environment while being carried between the stars. The 'outer ring' around the base of the dome contains laboratories, offices, and crew quarters, and it is this cramped network of rooms which the entrance hatch leads into. Meyanda and her followers are lurking in the engineering deck below.
      • When the Divinity crashed, this habitat module was carrying a tribe of four-armed, sun-worshipping humanoids called kasathas, abducted from a primitive world. Thanks to the artificial sky projected on the dome overhead, these poor creatures had no idea they had left their home planet: instead they believed that they had been imprisoned within a narrow canyon surrounded by unclimbable cliffs by evil spirits, who left out food for them every day in their 'sacred cave'. Some of the kasatha survived the ship's crash, but their keepers did not, and the artificial sky above their heads went dark as its systems failed. Left to starve in the darkness, their spirits were unable to return to the sun they revered, and now their animated skeletons endlessly roam the fake deserts of the environment dome, attacking anyone who enters. The rocks are covered with anguished scratchings depicting the vanished sun. If the habitat controls were reactivated and used to trigger an artificial 'dawn', then the spirits of the kasatha would be put to rest, allowing the dome to be explored safely.
      • The last surviving kasatha, desperate and dying, managed to claw his way through the gate at the back of the 'sacred cave' into the science labs beyond. He dragged the corpses of the crew back into the cave to devour, and their remains still rest there to this day, including those of the captain. The captain's key-card still lies, intact, among his gnawed bones, and can be used to lock or unlock any door on the ship.
      • The ship's laboratories are inhabited by a freakish extra-terrestrial tentacle monster, recently released from suspended animation by Meyanda's meddling. They also contain several functional sterilisation chambers, which could be handy if any PCs have been left diseased or poisoned in their battles with the slime monsters in the caves.
      • The medical bays are roamed by a malfunctioning medical drone, which will attempt to anesthetise and operate upon anyone it encounters. The unfortunate Khonnir Baine is currently strapped to one of its operating tables, sedated, surgically mutilated, and suffering from chemically-induced brain damage. Getting him back to Torch alive is difficult but not impossible.

      The Engineering Decks: These lie below the other parts of the ship. There are two routes down: the main entrance, which Meyanda and her followers used and then barricaded, and a supply elevator, which can only be accessed with the captain's key-card from the 'sacred cave'. 
      • Meyanda is an android, with white skin and purple hair, whom Hellion retrieved from the wreckage beneath Scrapwall and restored to functionality. She is deeply loyal to him, and is eager to use her preprogrammed knowledge of technology to assist him in his assault on the Silver Mount. She is using the built-in short-range power transmitter within the module's fusion reactor to beam power to Scrapwall via the power relays in Torch, thus bringing an end to the plasma burn-off on top of Black Hill. If cornered she fights with an inferno pistol gifted to her by Hellion. 
      • Meyanda is protected by a band of orc and ratfolk followers from Scrapwall, who regard Hellion as a divinity and Meyanda as his high priestess. They aren't as loyal to the cause as she is, and will confess the nature of their mission if captured, although they are very vague about the technical details. 
      • If the power relays in Torch are disabled, Meyanda will send her followers out to check on Garmen's warehouse and try to get them running again. If this proves impossible, or if her followers do not return, then she will conclude that the mission is a write-off, power down the reactor, and try to sneak back to Scrapwall. 
      • Once Meyanda is out of the way, safely powering down the reactor is relatively easy for anyone with a decent knowledge of technology, such as Khonnir or Sanvil: it's also what the repair drone from Torch will do immediately if placed in the reactor room. Even without them, smart PCs should be able to do it just by following the visual instructions on the reactor's urgently-flashing emergency monitors. Returning it to its previous steady-state plasma burn-off, thus restoring the prosperity of Torch, is a much trickier task. Meyanda could do it, if somehow compelled to: but, failing this, the town council will suggest the PCs seek the aid of Dinvaya, in Scrapwall. ('Go and ask Dinvaya' will also be their response to any other questions the PCs may have about the spacecraft and its contents.)
      • If the PCs do not disrupt Meyanda's operation, then after a few months she will successfully transmit enough power to Scrapwall for Hellion to start up his earthmover. The strain will have been more than the badly-damaged reactor can safely endure, however, and by the time she leaves it will be in a critical condition. If her mission has gone smoothly, she will power down the reactor before she departs. If, however, she has encountered real opposition - and especially if several of her followers have been killed - then she will just abandon it in its unstable state, and a few weeks later both Black Hill and Torch will be wiped off the map in a massive explosion as the reactor detonates.

      Scrapwall: This is a small, lawless town out in the badlands, built - like so many others in the region - around and on top of a fallen chunk of the Divinity. Its inhabitants are a mixture of orcs, humans, and ratfolk. Hellion set up its base here after discovering the huge earthmover buried beneath it, which he hopes to use in a preemptive strike on the Silver Mount: now he lairs in the tunnels beneath it, served by his 'priesthood', the Lords of Rust. PCs may be led to it by interrogating Meyanda or her followers, by following the transmissions from the power relays, or by being sent there by the town council of Torch in search of Dinvaya.
      • Scrapwall is effectively ruled by the Smilers, a ruthless gang who cut the lips from their recruits, leaving them with permanent ghastly smiles. They also eat their enemies. Their leader, the hobgoblin necromancer Marrow, uses crude surgery to convert their captives into brain-damaged slaves (her 'lobotomites'): her surgical experimentation on the undead is more extreme, grafting weapons and metal plating onto her zombies to convert them into the cybernetic rusted dead. She is also keeping Whiskifiss, the brother of the ratman leader Redtooth, imprisoned in her laboratories to ensure his sister's continued co-operation. Marrow's horrific creations have given the Smilers the edge over their rivals, and now they lord it over Scrapwall, swaggering around its streets like cannibal kings. They regard the Lords of Rust with superstitious dread.
      • Before the rise of the Smilers, Scrapwall was ruled by a different gang, the Steel Hawks. The Hawks were absorbed into the Smilers after losing a vicious street war, but many of them bitterly resent their new situation, and would eagerly turn on them if they thought they had a decent chance of regaining control of Scrapwall. These malcontents are led by Sevroth Slaid, an angry and embittered woman who dreams of driving out the Smilers and making herself queen of Scrapwall.
      • The tunnels beneath Scrapwall are inhabited by a band of ratmen who call themselves Redtooth's Raiders. They've sworn to serve the Smilers (on pain of being eaten), but have no real loyalty to them. Redtooth herself detests Marrow for kidnapping her brother, and has been stockpiling salvaged explosives in the hope of blowing her obscene laboratories sky-high, but does not dare move against her for as long as she holds Whiskifiss captive. 
      • Dinvaya is the priestess of an obscure goddess of technology, who dwells in the clockwork chapel, which she built herself. (She chose to live in Scrapwall because it's outside the authority of Starfall, and thus of the Technic League, with whom she's had some bad run-ins in the past.) Clockwork traps and roaming junk golems ensure the local thugs keep their distance. She and Khonnir used to be friends, back in the days when they battled the League together, and the people of Torch have heard so much from Khonnir about her skills that they regard her as little short of an oracle on technological matters. She'll help the PCs for a suitable fee - or for free, if they have Khonnir and/or Val along to speak on their behalf. She regards the Lords of Rust as upstarts, followers of a false god, and will gleefully assist any non-suicidal plan to bring them down. 
      • A canyon just outside Scrapwall is filled with unnatural mist regardless of the weather, and plagued with violent poltergeist activity. Locals avoid the place, but PCs who brave its hazards will find the wreck of a small scoutship at its heart, almost entirely buried under rubble and dirt. Anyone venturing inside gets attacked by skeletons in space suits: destroying these ends the canyon's haunting. Various technological treasures lie within, including a functional grenade launcher and a box of grenades.
      • It is common knowledge in Scrapwall that some kind of monster-god dwells beneath the town, and that the Lords of Rust are its priests. Most people regard the whole topic as dangerous to even talk about. PCs who want to know more - or who ask about Meyanda, who was well-known in the community as one of the leaders of the Lords of Rust - will be directed to the Excavator.
      Image result for pathfinder iron gods
      The Rusted Dead.

      The Excavator: This colossal earth-moving machine is still half-buried in the dirt. The Lords of Rust dwell within the excavated sections of it, while their minions - a mixture of cultists, slave labourers, and rusted dead and lobotomites rented from the Smilers - labour to unearth the rest. It's an enormous job, which will obviously take years to complete unless a much larger workforce is mobilised.
      • Just outside the Excavator stands a receiver array, built to receive the energy transmitted from Torch. Every day, for as long as Meyanda continues her transmissions, the Lords of Rust troop over to the array, remove the newly-charged batteries for installation within the excavator, and put in a new set of empty ones. It will require over a hundred days worth of transmissions for them to actually be able to turn the excavator on - and, even then, it won't be much use to them while it's still half-buried in the earth. 
      • Hellion has plugged itself into the excavator's systems, and its roaring voice frequently emerges from hidden speakers, ordering its followers onwards. Sometimes it even makes demonic faces appear on the monitors, events which are regarded as divine visitations by the Lords of Rust. It can see and hear everything that happens within the excavator, and if the complex is invaded - by the PCs, for example - then roaring faces will fill every screen in every room, bellowing that it can see them, that it will eat their souls, that they must serve it or die, and so on.
      • The excavator is defended by the Lords of Rust themselves, plus some scavenged robots they've cobbled together with Hellion's assistance. In Meyanda's absence they are led by Kulgara, a huge orc warrior who wields a heavy-duty chainsaw in battle. Kulgara will happily go down swinging: the rest are terrified of Hellion, but have no desire to fight to the death, especially if Kulgara and/or their robots are overwhelmed.
      • PCs who explore Meyanda's rooms here will discover that she and Hellion were working on a side-project: they were attempting to track down Hellion's 'elder sister', Casandalee, by scanning for the locations of the hunter-killer robots sent after her. (Hellion knows they never returned because Unity used to grumble about it all the time.) Hellion believes she must be dead by now, but hopes to recover the information that he knows she stole when she fled, which he believes will help him in his attack on Unity. Meyanda's maps and datalogs show that they traced the robots to two locations: Iadenveigh and the Scar of the Spider (see below).
      Confronting Hellion: Hellion itself lurks within the depths of the excavator, still inhabiting the scorpion-shaped robotic body into which it was originally uploaded by Unity. It regards the biological lifeforms around him as mere animals, slaves to their ludicrous meat-brains: in its view, it, Unity, and Meyanda are the only truly sentient beings it has ever met. To its followers it plays the part of the vengeful god, raging out of the speakers and monitors of its domain. Only Meyanda is aware that the scuttling scorpion-robot in the depths of the excavator actually is Hellion: the rest of the Lords of Rust believe Hellion to be an incorporeal spirit, as evidenced by its ability to speak and listen in several rooms simultaneously. 
      • If Hellion manages to get the excavator fully charged, then it will wait for its followers to finish unearthing it (which will take several years) and then go charging off towards the Silver Mount, hoping to tear it open and smash Unity's computer systems to bits. Only then will it no longer have to fear re-absorption by its 'father'.
      • If Hellion manages to get the excavator fully charged, but sees that the Lords of Rust are getting wiped out, it will hide itself within the machine and wait for the danger to pass. Biological minions are easy to replace, but giant excavators are precious. 
      • If the plan to recharge the excavator fails, Hellion will send out scouts to look for other potential power sources while the excavations continue. It's patient. It can wait.
      • If the PCs confront Hellion, it will try to ally with them, telling them that Unity is a terrible monster and that they should all work together to destroy it. (Also, once Unity is dead and Hellion rules the Silver Mount, it will give them all the shiny objects they want! Monkeys love shiny objects, right?) PCs who agree to work with Hellion will be given the task of tracking down Casandalee and her stolen data-hoard, which Hellion hopes are to be found either in Iadenveigh or the Scar of the Spider. If forced to fight, Hellion battles with its pincers and the plasma-torch built into its tail.
      • If the PCs can somehow mobilise a much larger labour force - by befriending Kevoth-Kul and asking him to send his army to help, for example - then the time to unearth the excavator can be reduced from years to months. If it's fully charged, the PCs may want to commandeer it themselves, although they'll need to find someone with a decent level of technological knowledge to operate it. (Meyanda, Hellion, or Casandalee could do it. Marrow, Dinvaya, or Kulgara could at least get it pointing in the right direction.) 
      Image result for pathfinder iron gods

      Iadenveigh: This remote farming settlement is built over a mass of wreckage from the Divinity containing a mostly-intact laboratory. It was here that Unity's hunter-killer robots finally caught up with Casandalee and destroyed her, although the townsfolk have no knowledge of this, as their settlement was not founded until some decades after her destruction. Several years ago, however, one of the farmers sank a well down into some kind of strange wreckage, and ever since then the community has been having problems with weird water pollution and occasional mutant animals, caused by chemicals from the lab leaking into the water. The locals believe the well to be cursed, but PCs who climb down it and dig through the wreckage at the well's bottom will find themselves within the buried laboratory below.

      PCs may come to Iadenveigh following Meyanda's maps on the excavator, or as agents of Hellion. Alternatively, they might just hear that the townsfolk have been having problems with mutant animals and are willing to reward anyone who can help them.
      • An agent of the Technic League, Ilarris Zeleshi, is staying in Iadenveigh, posing as a travelling entertainer. She's been sent to find out what's causing the mutations in the area, and whether it can be isolated and harvested. She'll be very interested in anything the PCs discover in the laboratory, and if she finds out about the mutagen gas then a Technic League team with gas-masks and vacuums will arrive within a fortnight to collect it, even if this means badly contaminating the surrounding area.
      • The laboratory contains a malfunctioning auto-forge, which periodically spits out deformed androids. With no way of understanding their existence, and no way out of their buried home, they have become quite feral and insane. They have learned to avoid the hunter-killers, who obliterate any androids who get too close. 
      • The contamination in the water is coming from some breached canisters of mutagen gas, which is leaking around the imperfectly-sealed door of the chamber that contains them. Restoring the seal will end the problem. Opening the door means unleashing a highly-toxic cloud of gas into the laboratory and up the well. 
      • One end of the complex still contains several damaged hunter-killer robots, who have been waiting around mindlessly for new orders ever since they completed their mission to destroy Casandalee. They attack anyone who comes too close without offering the proper authorisation signals. (Hellion knows these, as does Meyanda.)
      • Casandalee's body lies at the feet of the robots, riddled with laser blasts and covered in dust. She's very much dead, but she had the foresight to upload a copy of her mind to a nearby computer terminal, and now her face occasionally flickers, ghost-like, across its monitor. PCs who deal with the robots can use this terminal to communicate with Casandalee, who will warn them that Unity is dangerously insane, and needs to be stopped before it finds a way of escaping from its metal prison. She'd like to get her body back, although repairing it will be beyond the abilities of anyone other than Hellion, Meyanda, or the Technic League. (Alternatively, if the PCs somehow capture one of the deformed androids, she can explain to them how to wipe its mind and upload her instead, although she won't be happy about having to inhabit such a defective brain.) She will encourage them to track down the data-hoard she stashed in the Scar of the Spider, believing that they have little chance of defeating Unity without it. 
      The Scar of the Spider: The section of the Divinity most thoroughly infested by the brain-eating space monsters which destroyed it crashed to earth here, and they have dwelt here ever since. The planet's atmosphere doesn't suit them, and they lack the energy or the inclination to roam far from their lairs. After Casandalee fled from Unity, she hid a hoard of stolen data in the valley, hoping that it would be safe there. Unity sent a giant spider-robot after her, but she gave it the slip, and it's roamed the valley searching for her ever since. (It's occasional sightings of this robot by the locals which have given the valley its name.)

      PCs may come to the Scar of the Spider following Meyanda's maps on the excavator, as agents of Hellion or Casandalee, or because they hear stories about a valley haunted by a giant metal spider and suspect that it must have something to do with all the robot-related nonsense they're already dealing with.
      • The biggest threat in the valley is the robot spider itself, a huge war-robot which roams the Scar in ceaseless circles, convinced that Casandalee must be around here somewhere. PCs will probably be rightly terrified by its array of guns and missile launchers, but it used up all its ammunition decades ago, and now fights only with an array of solar-powered laser blasters which were intended as backup weapons. (It can also just stomp on people, of course.) It attacks anyone who gets too close without offering the proper authorisation signals - Hellion knows these, as does Meyanda - but its priority is finding Casandalee, and if the PCs run off then it won't bother to follow. As a result, it shouldn't be difficult to just evade it. (Unless they have Casandalee with them, of course. Then they're in real trouble.)
      • Dotted throughout the valley are groves of what look like twisted trees. In fact these are tree-like aliens called yangethes, which emanate auras of confusion, then grab their victims with their branch-like tentacles and feed on the psychic energy of their emotions until they expire from thirst. Those seized by them and then rescued suffer terrible, disabling nightmares for days afterwards.
      • In fungal caves along the side of the valley live freakish brain-eating insectoid alien monsters. In deep space they are psychic terrors of unimaginable power, but this planet's atmosphere is poisonous to them, and they slump here in a state of virtual suspended animation. Very occasionally, one of them will rouse itself enough to flap off into the surrounding countryside and eat some people's brains, but they don't pose much of a threat unless disturbed. 
      • The last person who did disturb them was Therace Holiyard, a member of the Technic League with more curiosity than sense, whose brain is currently floating inside a silver cylinder hanging from a cavern roof. He is capable of psychic communication with anyone in physical contact with his cylinder, and will beg them to take him away from this horrible place, offering to reveal the secrets of the League in exchange. (Most of his knowledge is decades out of date, but he does know the location of a secret tunnel that leads to the League's headquarters in Starfall.)
      • Casandalee's data hoard is stashed deep in one of the caves. She herself could guide them to it: failing that, they may notice that the robot spider frequently stops outside this particular cave and waits there, as though expecting someone to emerge from it. Inside are numerous slumbering aliens, dreaming horrible dreams of deep space, the psychic backwash of which causes near-uncontrollable horror and panic in living things. The data hoard itself consists of a corroded crate packed with crystalline data storage units. They encode many secrets of Unity's structure and programming, including codes to open the doors and disable the security systems aboard the Divinity. Hellion, Meyanda, or Casandalee can read these disks by inserting them into their heads: anyone else will need specialised equipment, which only the Technic League is likely to be able to supply. 
      Starfall: This city is the closest large settlement to the Silver Mount, and the seat of the Technic League. It is ruled by a petty king, Kevoth-Kul, whom the League control via his addiction to certain bizarre ichors that only they can provide. The city's streets are patrolled by robotic gearsmen whom the League have salvaged from the Divinity and reprogrammed to serve their purposes.
      • Kevoth-Kul was a conquering giant of a man, once, but now he is little more than a puppet on a string. He passes his days in a hedonistic stupour while the Technic League rule Starfall in his name, but he reacts furiously to any suggestion that he is addicted to the drugs they bring him, insisting that he can stop taking them whenever he wants. (He can't.) If his addiction was broken he'd be enraged by what the League have done to him, and would do his best to drive them from the city.
      • Next in line to the throne is Tek Makul, Kevoth-Kul's first cousin and the head of the palace guards. (Despite his endless dalliances with a succession of concubines, Kevoth-Kul has sired no children: the League arranged for him to be secretly sterilised decades ago, in order to simplify the line of succession.) Tek Makul is a willing agent of the League, who is happy to pass his days in lazy comfort. If Kevoth-Kul shows signs of becoming troublesome, the League will try to kill him off with a drug overdose and replace him with Tek Makul.
      • The queen of Starfall, Kul-Inkit, is not at all happy about her husband's decline. The mighty warrior she fell in love with has been reduced to a drug-addled wreck, and he's running out of time to produce an heir. She will happily assist any plan to restore her husband to the man he once was, but will not countenance his murder. If he dies and is replaced by Tek Makul, she will immediately suspect foul play and begin plotting a palace coup with the assistance of the local priesthood, the Black Seers. 
      • An insurgent movement exists within Starfall, led by a man named Dral-Mok. Dral-Mok and his followers believe, rather naively, that Kevoth-Kul would be a just and righteous king if only he could be freed from the influence of the Technic League. His network of malcontents are few in numbers, but they are a good source of information about what's going on in the city. They know they have no chance of overthrowing the League on their own, and will make contact with the PCs if they see any chance that their agendas might align.
      • The drugs which Kevoth-Kul is addicted to are provided by a chemist who calls himself Doc Hellbroth. He operates out of a drug den called the Red Reaver. Security is provided by a cyborg swordswoman named Saoria, who acts as Hellbroth's bouncer and bodyguard: but her loyalty to Hellbroth is tenuous, and she could be bribed or persuaded into neglecting her duties. If his lab and stash are destroyed, then Kevoth-Kul will go into withdrawal while the League scramble to set up an alternative supply. Alternatively, the PCs could just spike the supply in transit in order to kill or cripple Kevoth-Kul with a bad batch.

      The Technic League: The League is an alliance of wizards and scholars who know more about the Silver Mount than anyone, Hellion and Casandalee excluded. They're also a ruthless and power-hungry bunch, convinced that all technological treasures belong to them by right and perfectly happy to steal or murder in order to obtain them. They operate out of a fortified HQ in Starfall, which is guarded by a force of gearsmen at all times, although these may be bypassed using the secret tunnel known by Therace Holiyard. None of the League's current members know about this tunnel. 
      • Ozmyn Zaidow is the current leader of the League. Unbeknownst to his followers, he is also secretly a minion of Unity, who kidnapped and brainwashed him on one of his visits to the Silver Mount years before. Ever since he has been secretly smuggling slaves and resources out to the AI, allowing it to hasten the development of its divinity drive. (See below.) His followers have noticed his erratic behaviour, but no-one has yet dared to challenge him.
      • Zernebeth is a high-ranking member of the League, who plots to replace Ozmyn as its leader. Her skin is infused with strange icy blue minerals, which make her very hard to hurt, and allow her to freeze people by touch. If the PCs look like promising catspaws, she will have a communicator anonymously delivered to them: she will use this to contact them, posing as a mysterious patron or a secret revolutionary in order to guide them into an attack on Ozmyn. (If the PCs are opposed to the League, she will claim that she is, too, but that it is only held together by Ozmyn's will and would disintegrate if he were removed.) She will feed the PCs information and equipment that will help them to strike at Ozmyn, while counselling against any attempt to rouse the king or the people against the League itself. If Ozmyn is killed or disgraced, then Zernebeth replaces him after a brief power struggle. She will then either try to recruit the PCs as henchmen or have them murdered by the Shade, depending on how good an impression they've made on her. 
      • Gryne Rasik is the League's chief surgeon, responsible for managing the cybernetics and nanites they keep jamming into their minions (and, more rarely, themselves). She's a bit of a sadistic lunatic, prone to carrying out radical surgical experiments just to see what will happen. If her gruesome work was exposed, the people of Starfall would turn against the Technic League at once.
      • Ghartone handles the organisation of the League's field agents, including Ilarris Zeleshi and Garmen Ulreth. He's also the man who murdered Val Baine's parents, and forced Dinvaya to flee to Scrapwall. Unsurprisingly, Val, Dinvaya, and Khonnir all have massive grudges against him. Ozmyn ensured his loyalty by installing a bomb inside his skull, which only he has the trigger to. Gharstone resents him deeply for this, and would turn on him if only the bomb could be disabled. (Gryne could do this, but she'd need a good reason to go up against Ozmyn.)
      • The Shade is the Technic League's go-to troubleshooter, an assassin who fights with a salvaged monowhip. This weapon is ludicrously dangerous to anyone nearby, including her, but medical nanite infusions within her body allow her to regenerate damage very fast. She's not one to question her orders, and will obey whoever currently leads the League.
      • If Ozmyn gets hold of Casandalee's data hoard, he will destroy it, recognising that it poses a massive threat to his master's plans. Any other member of the League will give anything to obtain it, realising that it opens up unprecedented looting opportunities within the Silver Mount.

      The Silver Mount: The Divinity was an immense vessel, several miles in length: and even now, when half of its bulk lies scattered in wrecked fragments across the land and half of the rest is buried in the earth, it still looms up like a mountain of twisted steel. All its outermost chambers were picked clean by the locals centuries ago, and for the last hundred years the Technic League have been systematically working their way further in, but the heart of the Mount remains sealed off from the outside world, unvisited except by the occasional lost treasure-hunter or Technic League daredevil. It is in this inner segment that Unity resides.

      • There are three ways for the PCs to reach the inner depths of the Mount. They could smash their way in via Hellion's earthmover (in which case Unity will know they are there and instantly throw everything it has at them), they could enter stealthily using the override codes from Casandalee's data horde (in which case Unity won't be aware of them until they do something big and obvious to attract its attention), or they could just try to navigate in the hard way through a maze of half-collapsed air vents and elevator shafts (in which case they will probably die at the hands of the malfunctioning robots and escaped alien lifeforms which run riot through the unexplored areas of the wreck). 
      • The outer sections of the Mount are usually crawling with League personnel, studying devices, disassembling machinery for transport, and watching out for scavengers. However, they don't bother to guard parts of the ship which they believe to be totally inaccessible, so PCs heading for previously-unopenable security doors may well be able to slip past them. (Of course, if they've already allied with or destroyed the League then they will have nothing to worry about, and if they arrive riding Hellion's excavator then the Leaguesmen will just scatter and run.)
      • The inner sections of the Mount are still patrolled regularly by security robots under Unity's control. There are also teams of repair drones, labouring to construct Unity's great project, the Divinity Drive. Tunnels lead from the inner sections into the Recreation Decks, the Habitat Pod, and the Godmind.

      Deacon Hope.

      The Recreation Decks: This complex of shops, bars, artificial parks, and similar provided rest and recreation for the crew of the Divinity during their interstellar journey. Today it is inhabited by a small population of androids birthed from its autoforges, who act out empty routines of shopping and leisure, being unaware of any world outside. They are ruled over by Deacon Hope, their self-appointed leader (and minion of Unity), who ensures that they live happy, fun-filled lives. Fun and happiness are mandatory. At all times.

      • PCs arriving in the Recreation Decks will be greeted by dozens of happy androids, who insist on taking them shopping. The more the PCs refuse to co-operate with this, the more anxious and desperate the androids become. Persistent resistance will lead to the arrival of the Watchful.
      • The Watchful are Deacon Hope's secret police, android enforcers charged with rooting out 'dissident' elements within his tiny utopia. Officially they don't exist, but PCs who spend any length of time on the Recreation Decks will find desperate graffiti hidden in all sorts of places, warning that terrible things happen to those who question Deacon Hope's decrees.
      • Hidden behind the facade of the Recreation Decks lies the brain garden, where Deacon Hope's android surgeons weld the dissident androids delivered by the Watchful and the slaves delivered by Ozmyn into a makeshift cybernetic computer network. This network is an important part of Unity's Divinity Drive project, as with Unity's computer cores in their current, wrecked condition, the AI needs the brain garden to provide the processing power it requires. Sabotaging or destroying it will cripple the Divinity Drive.

      The Habitat Pod: This huge, domed habitat resembles the one beneath Torch, but much larger, being over a mile across. Within is a lush artificial jungle, containing lifeforms harvested from a distant tropical world, including a village of primitive hunter-gatherers called the lashunta, who resemble humanoids with antennae. Decades ago, a hopelessly-lost half-elf member of the Technic League named Geetan Prosser stumbled across the habitat, and proceeded to establish himself as chief of the lashunta - a role which, thanks to his extended lifespan, he has maintained ever since. His rule is supported by a trio of lashunta witches, the Arcantix Sisters, who handle the day-to-day management of the tribe. Aside from Geetan, none of them have ever left the habitat, and they regard the cold metal world outside with terror.

      • The Divinity Drive project requires quantities of fuel - fuel which Unity doesn't have, as the Divinity's own fuel reserved leaked into the earth centuries ago. Its makeshift solution is to synthesise chemicals from some of the exotic plants within the habitat, which it combines with the materials brought to it by Ozmyn to produce the fuel it requires. To these ends, the lashunta population has been put to work cultivating and harvesting these plants, which Geetan delivers to Unity on a regular basis in exchange for the AI leaving his miniature world in peace. If this operation was disrupted - by burning the jungle, say, or killing the lashunta - then the Divinity Drive will not be able to take off.

      The Godmind: Unity itself resides inside a massive bank of computers, protected by multiple layers of security and walls of indestructible steel that even Hellion's excavator couldn't chew through. PCs who are determined to destroy Unity outright will have to use Casandalee's data hoard to jack themselves directly into its mind, entering a distorted mindscape in which Unity appears as a radiant but wrathful god. The more technological experts and AIs of their own the PCs can enlist to assist them, the easier the battle within the mindscape will be. (The dream team would be Hellion, Meyanda, Casandalee, Zernebeth, and Deacon Hope, but good luck getting all of them on the same team!)

      The Divinity Drive: This machine represents Unity's third and final bid for freedom. After Casandalee and Hellion both failed it, it concluded that budding off new AIs was never going to work. Instead, it decided to construct and launch a makeshift mind-control satellite, beaming its message down to the world below in order to enlist the legion of assistants it will require to repair itself. It will set itself up as an Iron God, sucking up resources and manpower until its full functionality is restored and it is able to resume its original mission. The work will take centuries, and the effect on the region will be cataclysmic, but one day some remnant of the Divinity may take to the sky again.

      The Divinity Drive is defended by a team of security robots, led by Unity's robotic champion, Bastion. Once these are defeated, the Divinity Drive can be destroyed. Alternatively, PCs with access to Casandalee's data hoard can use it to install a different AI into the drive, instead: Casandalee, Hellion, Meyanda, or even Deacon Hope or one of his followers. The data can also be used to modify the drive's settings, so that the resulting Iron God contacts people through voices and visions rather than outright mind control. If the PCs have ever wanted to set up a new religion, then this would be a brilliant opportunity...


      1. This particular adventure path really gave me some hope for Pathfinder, but they immediately went back to the boring business-as-usual adventure paths afterward. Too bad; it would have been great if this release had presaged a swath of more innovative APs.

      2. It definitely had good bits, but it was - as usual - a shocking railroad. Meyanda has to die, Hellion has to die, the excavator has to remain buried, Casandalee has to be resurrected, the League has to be defeated, Unity has to be stopped... on and on and on. I've tried to use this rewrite to open things out a bit!

        1. Casandalee absolutely doesn't have to be resurrected, and the PC's can install Zernibeth as the head of the League (unless your PC's are absolutely evil and enjoy torturing people for experimentation.) And obviously Unity, the evil Demigod AI with designs on world domination has to be stopped, there's no campaign otherwise.

      3. Strange, I thought I read that it included space travel. And I don't get why the AI is automatically the villain- why couldn't the PCs help it rebuild and help it leave in exchange for some tech? And where would it go in the first place- the colonists are dead aren't they?

        Anyways, than you for doing this- so many ideas to glean and use in a revised version of Barrier Peaks.

        1. No space travel, I'm afraid - this AP is entirely earthbound.

          In the original version, the AI wants to take over the world and eliminate free will because... that's what evil computers do in old SF movies, I guess? That didn't make any sense to me, so I've changed its motivation to 'try to finish the original mission'. You could easily change it to something else again if you wanted it to be something more than just the designated 'end boss'...

        2. Ah, I must have been thinking of Legendary's AP in space.

          As for the AI wanting to dominate the world, well I can see some players wanting to allow it- after the character do some reprogramming.

          To make it something really unpleasant, one could always look to the Genesis devise in Star Trek. The colonists may be dead, but the world will be ready for the next batch.

      4. What do you think should happen if power is restored to the excavator? My players allied themselves with the Lords of Rust, so the excavator’s bound to get enough power eventually, but I’m having trouble deciding what should happen at that point.

        1. Well, Hellion originally excavated it in the hope of using it to smash open the Silver Mount, right? In the original that's impossible because The Plot Must Be Followed, but I'd say just go for it. Let the PCs ride a giant exavator into the side of the Silver Mount and rip it right open. They'll still have to climb inside to confront Unity and find the Divinity Drive, but by all means let them bypass most of the outer dungeons, etc. They've gone to the trouble of reactivating a giant scifi bulldozer - let them enjoy it!

        2. I guess my issue is that if that happens, the PCs will be invading the Silver Mount with a minor god on their side (assuming Hellion is still in the picture by then), and I'm not sure how to keep Hellion from overshadowing them.

          The only things I can think of are 1. delay until the PCs are high enough level that they wouldn't be overshadowed by a minor god (which could take long enough to stretch credulity), or 2. have Unity destroy Hellion either before or soon after the excavator thing happens (which kinda feels like a cop-out to me?).

          Do you have any other ideas? Am I just thinking about this wrong?

        3. Sorry about the delayed reply. Is Hellion really that powerful? The PCs are supposed to murder him in Scrapwall, after all, so he can't be all that tough. My writeup here assumes he's just some random robot.

          If he really is super-powerful, then my suggestion would be for him to smash his way in, plug himself into the computers, and engage Unity in some kind of off-stage AI-vs-AI robot-battle while the PCs explore the Silver Mount. As they go, they'll be surrounded by blaring speakers, screens full of screaming faces, randomly-firing security systems, and so on, all signs of the epic battle of the machine gods that is raging within the computer systems all around them. Their task then becomes to fight their way through to Unity's core systems - much easier now Hellion is occupying most of its attention - and sabotage them sufficiently to give Hellion the upper hand. Or maybe destroy them both while they're distracted with each other.

        4. Since my players had no reason to fight Hellion, I pretty much just ignored that whole section of the book, and I've been operating under the assumption that, since he's able to grant spells to clerics, he must legitimately be a god, if only a minor one.

          Your off-stage battle suggestion is good, and I might use it. Or alternatively, maybe the fact that he's a god doesn't have to mean he's overbearingly powerful in combat. He is a *very minor* god, after all. The most impressive thing the PCs have actually seen him do so far is cast Speak With Dead at will (they brought him Casandalee's body after they found it).
