Random Space Encounters

  1. A debris field from a space battle that happened years ago. It may still contain useful salvage.
  2. SPACE PIRATES!
  3. A mob of colonists trying to break into the headquarters of the company that founded their colony.
  4. PCs encounter their own starship, only it’s from the future, and things have apparently gone horribly wrong. Investigating ship records indicates whatever went wrong, it should happen in the next few days…
  5. A planet inhabited only by robots; the original inhabitants, who created the robots, all died off for some reason. Maybe the robots want the PCs to stay, and won’t take no for an answer.
  6. A xenophobic race of alien religious fanatics inform the PCs that they’ve violated their sacred space and now must atone for defiling it – whatever ‘atonement’ may mean to them.
  7. Scrap-scavengers set up a decoy distress beacon to draw the PCs’ ship into a trap.
  8. An uprising between miners and overseers in an asteroid belt has caused chaos in the region; perhaps the PCs had originally planned to land in one of their docking stations for repairs, unaware of the turmoil that’s breaking down the social order.
  9. A member of a warrior race decides to duel one or more of the PCs for the honor of it, to prove he is the greatest warrior in the galaxy.
  10. Parasites infest the PCs’ starship, causing all kinds of trouble; since they’re notorious for their reproductive rate, no civilized docks or planets will allow them to approach until the problem is eradicated.
  11. A derelict ship. The cause of the crew’s demise is in question, but the vessel may be carrying valuable or important cargo.
  12. A space habitat which serves as home to a splinter faction of social outcasts or isolationists from their own race. They may be friendly, or they may be cult-like; in either case, they may have demands of the PCs.
  13. A starship graveyard, full of old hulks and battle-damaged vessels. May be crawling with scavengers, both technological and bestial. Perhaps it’s haunted?
  14. A star system is about to be consumed by a black hole. The natives of its one habitable planet are trying to gather all of their people, cultural and historical treasures, and other important things onto as many massive ships as they can as quickly as they can. But the planet has become the target of scavengers, pirates, looters and slavers, all of which are trying to make a profit off of the planet’s doom.
  15. The PCs’ ship suffers significant damage, requiring them to set down on the nearest planet before radiation or something kills them all. While on the relatively habitable (but probably not hospitable) wild planet, they must survive the strange environment and its natives, if any, until they can complete repairs and get spaceborne again.
  16. The Seven Sentients: A band of aliens, piloting an unarmed vessel, are on the run from some bigger, badder aliens (who are most definitely armed). If the PCs save them, the aliens entreat the PCs to come back to their homeworld and run the tyrannical bandits/would-be-overlords off their planet.
  17. Bounty hunters are pursuing the PCs, either because of a mistaken identity or because of something the PCs actually did (perhaps unknowingly?)
  18. An alien comes to the PCs, begging that they take him/her/it aboard their ship. It is a fugitive, being pursued by other aliens. The fugitive has several useful skills, but is obnoxious and may not be trustworthy. What are the charges for which the fugitive is being pursued?
  19. Giant psychic space-worms project a field that causes sentient beings to slip into a dreamlike state, helpless until the worms can devour the PCs’ starship. But the space-worm’s mind collects the memories of those it devours, and the PCs may learn valuable information in the collective dream-world – not only how to defeat the space-worm, but maybe something of great value that they can pursue after they escape their current predicament? Also, elements of the PCs’ own subconscious minds may manifest here, from nightmares of past traumas to secrets they may not want the other PCs to know about – oops, too late!
  20. A shapeshifter impersonates one of the PCs’ crew, trying to obtain information about them to give to the Space Ninja Clan. The shapeshifter regularly sends reports back to the Clan, who prepare to strike at the PCs’ friends and allies. Who hired them to target the PCs? Is it personal? Could the Space Pirates help them against their old enemies the Space Ninjas? And what would it cost the PCs to arrange something like that?
  21. Alternatively, the shapeshifter is attempting to identify a suitable mate from among the crew by having different kinds of interactions with each member, deliberately sparking unusual situations. The shapeshifter is a member of a race that is dying, but may mate with any species it can emulate. This could be a good opportunity for some “what if?” scenarios – what would happen if the ship’s engineer started getting romantic with the captain? What if the ship’s security manager started a fight with the pilot? What if the crazy fugitive suddenly started acting completely sane? In the end, the shapeshifter could be either a tragic figure, doomed to continue searching elsewhere in the galaxy, or it could become a valuable addition to the crew…so long as the pregnancy was assured.
  22. Alien scientists want samples of the PCs to study, dissect, clone, etc. They may try to trick the PCs into surrendering their tissue, or they may threaten them openly…or they may offer them some superior technology in return (to them, it’s a toaster-oven, but to the PCs, it may as well be magical).
  23. Relatively primitive traders approach the PCs, wanting to trade furs or something. If the PCs agree, they might effectively open trade with a new world…or perhaps they’ll suddenly be targeted by an entire race’s worth of primitive traders, hoping to make a profit off of the PCs.
  24. Aliens the PCs aided in an earlier encounter arrive to return the favor.
  25. Something is causing a subspace communications blackout in the area. It could be a leftover mine from an alien conflict, it could be some kind of alien creature or stellar phenomenon, or it could be that someone is deliberately jamming the PCs’ communications.
  26. Primitive aliens worship the PCs as gods; they live among the trash discarded by spacefarers, and have created a cargo cult surrounding the offworlders.
  27. The PCs discover a ringworld in severe disrepair – portions of it are frozen and lifeless, but patches are completely habitable. What marvelous vegetation, minerals, and lifeforms will they find there? Ruins of the ringworld’s architects? Other aliens competing over habitable territory? Fugitive aliens trying to make a new home for themselves?
  28. The PCs land on a planet which is actually alive, under a single intellect – though they probably won’t realize it right away. What sort of things does a planet want?
  29. An area where the concentration of interstellar hydrogen is slightly higher than surrounding space. Exiting!
  30. An area where the concentration of interstellar hydrogen is slightly lower than surrounding space. Astounding!
  31. A black hole the ships sensors failed to detect due to malfunction. Everybody dies, please create new characters.
  32. A tiny chunk of rock hits the ship’s hull at a relative velocity of fuck-you kilometres per second.
    This shouldn’t happen, the ship has shields to stop that sort of thing. A material that can get right through shields like they aren’t there would be very valuable
  33. An exact copy of earth, circa 1947. The party arrive just in time to pick up a distress signal from a known and friendly alien species.
  34. alternately, said copy of 1947 earth is accurate in all respects bar one: In place of humans, the dominant species are the greys.
  35. A rusty old generation ship, the inhabitants of which have devolved to primitives who worship its central computer as a god. The computer itself believes this to be true.
  36. A death world (harsh climate, unbreathable air, pools of acid, dinosaurs etc) that is also secret home of the tastiest meat in the galaxy. The corporation who produces said meat wish to keep their secrets.
  37. They encounter a massive yet harmless spacefaring species, its body however is occupied by an alien race living a parasitic existence off the creature … possibly they think of the creature as some kind of deity … either way, your in the locals air space.
  38. THE INCREDIBLE SPACE KONG OF THE KING OF M’KEYS!!!!!
  39. SPACE ROBOTS! That aren’t really robots, but a culture of dress-upped cargo cults that somehow got their hands on FTL technologies and thought they were having some sort of extended divine vision (which, since getting high and praying and human scarifices are their major cultural pasttimes, isn’t the strangest thing they’ve “seen” before) instead of actually in space.
  40. The aforementioned four in a huge galatic battle against all sides plus one.
  41. Space Amazons! a nano-phage killed all their men and now the PCs have shown up…
  42. an anomalous field that inverts all numbers stored in computer systems. Hope the ship can be flown without them…
  43. a killer Nanobot. There is only one of it, though it answers to Swarm, talks like Yoda (Size matters not) and belives itself to be the last remnant of a proud warrior culture (That is to say, its flesh eating nano swarm) aside from being the worlds smallest klingon, Swarm is very adept at nanite design, and would serve as a universal template. If He can be convinced to cooperate. (atom Ant cartoons may help, he loves them)
  44. An alien has the innate ability to swap bodies with another, and takes over one of the crew, leaving the crewmembers mind in it’s old body. The alien raises some questions when it acts wierd, while the crewmember has to convince everyone that anything has happened at all. Based on Turnabout Intruder and some Voyager episode I can’t remember the name of.
  45. A ship full of extremely angry colonists, armed with WMD’s and headed straight for Earth. It is a generational, sub-light ship, and it’s whole culture is based on some twisted version of whatever legitimate grievances the original colonists had. The ship itself will not reach Earth for thousands of years, but there is no reason to think that they will be any less angry when they get here, and thier weapons technology is actually quite impressive. So the crew must decide how to deal with this, try to alter thier culture, try to destroy them, or just leave them and let Earth deal with them in the future?
  46. A weak distress signal from a nearby asteroid belt leads to an intact but out-of-fuel warship from the last conflict. All the crew have died, but the then-experimental-AI in the main computer is strangely unforthcoming about how.
  47. A weak distress signal has been picked up by the inhabited fourth planet of this system and the players’ ship is the only one which might be able to generate an intercept vector before whatever it is falls into the sun.
  48. An archaeological expedition to an uninhabited planet nearby is overdue, and the sponsors would like the PCs to investigate.
  49. The PCs have conducted a brilliant piece of diplomacy to get sole trading rights to this planet’s (fairly primitive) alien culture. At the celebratory feast of eternal friendship, all is going well…
    …until the less primitive humans from the lost colony on the other continent drop out of the night sky to conquer the PCs’ new friends.
  50. A giant floating tree at least moon-sized is following the ship
  51. The stars are disappearing
  52. Crew members suddenly forgetting scientific skills
  53. A derelict starship of a design only just on the drawing boards. No life signs, nothing left of the crew, and running a suitable handwavium scan (or just managing to retrieve what little is left of the logs) indicates that it must be several thousand years old.
  54. The obligatory omnipotent-seeming alien shows up to judge humanity, based quite naturally on the virtues of the player characters. Good luck!
  55. As above, except it’s a prank. Hey, quasi-omnipotent aliens need some cheap laughs, too!
  56. As above, except the alien is overzealous and at least decades ahead of schedule and will either back off once the PCs find out or else find themselves in suddenly trouble with their superiors who only just found out they jumped the gun at an appropriate moment.
  57. Sensors register a “dead” torpedo or military drone launched years ago in some interstellar war or other. It should long since be inert, but just as the ship draws close to dispose of it it suddenly powers up…
  58. Old food left in an abandoned fridge mutates and slowly kills the crew while in hyperspace.
  59. A mind controlling cactus attempts to turn the crew against each other.
  60. Two new life forms, a giant eel and a giant lizard-cat are fighting in open space attempting to claim the sector/system as their own territory.
  61. A massive crystalline alien life form is approaching a friendly planet. If communicated with it explains it needs to absorb large concentrations of a radiation that is produced by elements abundant on this panets moon in order to reproduce, unfortunately the only way it can do this is by swallowing the elements, effectively eating the moon. Obviously the planets inhabitants are in no mood for the massive environmental destruction losing their moon would cause so its up to the players to work out a solution then get both sides to accept it in order to avoid a potentially planet wrecking battle.
  62. A massive heat bloom erupts under the polar ice cap of a nearby planet. What will the players find when they investigate?
  63. So you saved the ship/planet/local solar system by stopping the unidentified object from crashing into you/the planet/the local star and even managed to bring it on board for study, now what will you do when the hither to unknown and highly advanced alien race haul you in for interrupting the space funeral of their emperor. You can understand little of their speech except the phrase ‘denied eternal life and rule for millions of years’ which seems to indicate you might be in a spot of bother.
  64. space whales
  65. a derelict ship appears. Literally from nowhere, it just pops into existence. Historical records indicate that this exact ship has appeared before. It shows up once every century or so and never sticks around long. Do you dare investigate.
  66. a ship made entirely out of giant greenhouses wrapped arround an artificial heat / light source floats by. There are many lifesigns but no response to hails or other signs of habitation.
  67. This planet is flat.
  68. An automated monitoring post suddenly comes online and accuses the heroes of being Artificial Intelligences in clear violation of the Abominable Intelligence Act, and then it opens fire.
    Ironically, the monitoring post is actually being run by an AI that has been brainwashed into thinking it’s a biological entity threatened from all sides by robots that want to exterminate its species.
  69. A hollowed out asteroid filled with water, colonized by descendants of Terran squids. They would like to purchase anything you have that’s recyclable, and in exchange they offer these new firing algorythms they’ve been working on in their spare time. Also they’d like to run all their water through your filters if that isn’t too much trouble because it’s getting kind of stale.
  70. Your ship is attacked by an Evangelical Nano-Swarm, which begins to carve bas-reliefs of religious iconography all over your ship’s hull, depicting stories of martyrs and miracles. This won’t compromise the hull’s integrity, but the added ridges DO make you more noticeable on radar.
  71. A dead Ringworld that has drifted away from the star it once encircled. Everything on it is dead and frozen, though in one valley, you detect that some tombs in a certain valley still penetrate through the ice layer…
  72. A very exclusive gambling den aboard a stolen Authoritarian Regime cruiser. The stakes are high, entrance is by invitation only (or if someone inside vouches for you). What makes it interesting is that the gambling hall is inside the main reactor, and losers can wager certain numbers of glasses of radioactive water they are willing to drink, as tokens instead of money.
    If you’re very lucky, you’ll rake in enough to be able to afford the gene therapy to repair the radiation damage.
  73. Space Hulk
  74. A space station that is entirely void of life. Or appears to be. When they dock, everything is as it should be, except that when they look out the windows, it is not orbiting the stellar object it was when they docked. When they take off again, they’re in an entirely different piece of the universe.
  75. Dyson Sphere.
  76. A completely empty dyson sphere.
  77. They come across a strange planet in the far reaches of space. It’s not on any of the maps or star charts. They almost fly right into it. Their scans can just barely penetrate the atmosphere, all they detect is a massive amount of biological matter on or near the planet.
    They may choose to ignore it or might explore this strange planet. Upon entering the atmosphere they’re met with a nightmarish scene. Writhing black tentacles cover the entire surface like some sort of hideous forest. They then detect a massive energy signature. The energy is coming from a massive temple built upon the service, in the temple is a cult of humans complete with black robes, chanting, etc. Upon further investigation they discover the cult is actually worshiping the planet, the planet is just one huge organism. The cult believes that it is a god and wish to use it to ‘devour’ other planets."
  78. You pass near an enormous construction site and decide to try and swipe some construction materials.
  79. Your ship picks up a nonstandard beacon, leading you to a spacefaring race’s first ever space probe. You intercept it, take the trinkets placed inside it and launch it back to its homeplanet.
  80. Your ship gets flagged by a group of marooned alien soldiers asking for a ride home. Do you take them in?
  81. Your ship detects what appears to be a colossal periodic table floating in space with pure samples of the elements. You get as much of any one element as you can carry.
  82. You find a planet indiscernible from you own home planet at first sight, and decide to check it out. Commence doing whatever you’d do on a planet, with one small difference the players have to find and possibly exploit.
  83. One of the PC’s owes a significant amount of money to some guy. He tracks your ship down and shows up with slightly superior firepower.
  84. A group of aliens who admires your race for some unknown reason clings to your ship and begs of you to come down to their planet and visit.
  85. After a peculiar teleportation accident, the players find themselves stranded on a jungle planet teeming with monsters. The players must now survive in the wilderness until help arrives, and find their feet.
  86. They players encounter a large starship drifting in space, seemingly without any lifeforms on it. When the go into it, they start to hear religious chanting. The ship’s inhabitants are in fact incorporeal energy beings whose music ensemble is on a galaxy tour. They invite the players to a fiesta, where food, alcohol and song are aplenty. However, the beings become a bit too fond of their new friends. Will the players manage to escape back to their ship, or will they join the choir invisible?
  87. Major Xu’Thlong, a member of a species of mile-wide worm-like creatures known for their great appetite and fast metabolism, has just had a fine meal at the local McHarald’s. While still in hyperspace, he orders his men to empty the garbage tanks. Unfortunately for the players, their ship is in the wrong place at the wrong time. Because its hyperspace controls are jammed, it’s unable to change course. A major shitstorm is on its way.
  88. The players arrive at Danthia, an enourmous gas giant with a thick atmosphere. Many an adventurer has come to Danthia’s floating mining complexes in search of riches and perished. Although Danthia is inhospitable to life and often ravaged by enormous thunderstorms, every cloud has a silver lining.
  89. A remote research outpost experimenting with teleportation technology has opened a portal to Hell.
  90. Survivor horror mode: the party comes across a derelict drifter colony. They board to resupply/investigate, and then things get all Event Horizon on them.
  91. A derelict ship or station where a demonic presence provides “Whatever the party expects” to destroy them.
  92. They are forced to make a blind jump after being chased by some rather hostile aliens/pirates, when they come out the otheDIVE DIVE DIVE HIT YOUR BURNERS PILOT!
  93. A distresses beacon from a..
  94. Crippled, drifting ship.
  95. Lifeboat from a larger ship.
  96. Drifting person in a space suit.
  97. A tiny outpost or colony…
    Where:
    • Everybody is dead! You can salvage what you like, but somebody might have some questions about where you got this stuff.
    • Pirate Trap! Raiders, pirates or freebooters wait for somebody to come investigate, then pounce, trying to take over your ship.
    • Hostile Alien! The ship, suit, lifeboat or colony is infested by an aggressive, hostile alien life form.
    • Battered survivors! People that need food, medical attention or just transport to somewhere safe are still alive. While they can’t offer very much in return, it’s a way to get safe, legal salvage rights and do a good deed.
  98. Space Hulk AND
1 Mutated ancestors of the crew, filthy warp-tainted spawns which can only be redeemed throurgh incineration.
2 Same as above – but it’s mutated xenos we’re talking about!
3 A bunch of orks. Those greenskins infest all the galaxy, and here they split into gangs and eagerly fight each other or any newcomers.
4 Chaos dreadnought filled with bloodlust is lurking thurough the decks and bays of immence ship. He will attempt to destroy PC’s lander and docking bay before saying hello.
5 Small, deranged hermit techno-cult which boarded this once devoid of life vessel and tuned its cogitators and subsystems to near-perfect condition. They are very disappointed by your interference. Very disappointed.
6 Stasis-chamber with Eversor Assasin inside. Emergency activation ritual is almost complete, a small interference might be enough to do the trick.
7 Fallen space marine apothecary with gene-seeds collected by him. Who knows how being lost in the warp altered them?
8 Strange skeleton-like mechanisms are spread across the ship, mostly in cargoholds and workshops. They look lifeless… for now.
9 Your average human crew. They desperately try to repair their ship, but with little sucsess. If a visitor touches one of them – he will turn to dust, and this is when the party begins.
10 Iron Man AI from legendary times of Golden Age. He is so glad to see living, breathing human beings aboard – his former guests died after a mere century of his favorite game.
11 Ruthless rogue trader was here before you and left armed guards to keep relics and treasures aboard secure before he arrives with transport voidship and escorts.
12 Genesteelers. How very original.
13 Cargohold has everything needed to perform Exterminatus upon a planet – viral bombs, cyclonic torpedoes and so on. What else is inside is already irrelevant, question is what planet was condemned, why, and is it still possible to deliver the payload before this planet causes more harm?
14 Hopelessly mad psyker screams absurd things in his delusion, and he is the only one who is alive of all the crew.
15 This once was a piligrim transport with huge statue of the god-emperor decorating the main cathedral. Today a cult with bloody, delusional parody of the Creed worships the statue and offers it sacrifices – heretics, mutants and outsiders. Especially outsiders.
16 There is a huge black mirror in captains quarters. It reflects everything a tiny bit warped or with a tiny lapse in time, and this is very unsettling – for a good reason.
17 Small black box with one activation rune on it – it looks like archeotech or xenotech. Is someone is suicidal enough to push the button the box will play a short tune and nothing else will happen… at first.
18 Stasis chamber with another kill-team fully equipped for combat.
19 A group of acolytes with their weapons drawn and a cooling body of radical inquisitor armed with demonic weapon.
20 Squats – these exodites escaped the Great Devourer thanks to this space hulk.
21 Tzeentch. He plotted your arrival and has a proposition you wan’t be able to decline – or so he believes.
22 The ship is sweeped clean, there is no damage and no traces of how this all happened.
23 The crew is messily murdered by daemons and according to captain’s log this ship has came from grim future of the 43d millenium after setting sail into the warpstorm. This log contains all kinds of interesting notes about M43 – but were the logs twisted by immaterium or not – that is the question.
24 Stasis chamber with fully-equipped Word Bearers chaplain from the times before Lorgar started having doubts about Imperial Truth.
25 Corpses of PC’s lie on the deck of the ship as they arrive aboard. This time-warping trap is caused by warp, and now PCs have very little time to alter the present and make them becoming corpses they have seen an unlikely variant of the future.
26 All logs and data-crypts are deliberately and throughly destroyed, Machine Spirit is exorcised from the ship, all displays show only static. But something keeps drawing your attention to these displays. Maybe something is still hidden within?
27 Techno-miracle of a ship and Mechanicus explorator fleet which is eager to get it. So eager, in fact, that it can begin confrontation even with astartes or the inquisitor of your ship – but this strategy implies no witnesses left alive.
28 Previously unknown STC. Looks like it is working fine. Yeah, indeed.
29 Tau vessel is eager to repair the crippled imperial transport ship and deliver its cargo – poor, hungry imperial refugees and war orphans to Tau Empire for the greater good.
30 Ship is devoid of life but filled with marble statues of crewmen and officers at work. Auspex shows that thi is just a marble, but the statues look uncannyly alive.
31 Immense librarium.
32 Heavy armored vehicles, which bear markings of Mars forges but their design doesn’t look familiar – or even human.
33 Golden ring. If you heat it you will see runes looking like eldars, but the language is obviously different.
34 Duct Tape STC
35 Eldar Webway portal.
36 There is a single Magos aboard, and the cargoholed is filled by spare parts of some immence mechanism said Magos is fanatically eager to assemble.
37 Some old heretical writings.
38 Smaller ship is docked to bigger one, both ships are devoid of life. Obviously, smaller ship’s crew wanted to loot the bigger one but something gone very wrong.
39 12 000 Astartes Bolters – too bad that STC for their bolts was lost 4 millenia ago.
40 The whole space hulk is but an anchor for huge and puzzling warp-anomaly.
41 The ship is haunted by former crew and ghosts can affect the events aboard. The only way to get rid of them is to give their corpses to the void.
42 This was a flying laboratory of Magos Biologos, and something gone wrong during experiments. What exactly? Crewmen turned into zombies are a good hint.
43 Statues of angelic beings which close their face with hands as if they weep. Statues never appear on the same place twice, and no crew is to be found. The only thing you can find is “Don’t blink” written on the bulkhead with blood.
44 ually, crew can keep their existance even in this state and the will nicely ask any intruder to leave using writings in blood. They will only be nicely at first.
45 Crew, turned into savage cannibals.
46 This is inquisitorial Black Ship, where cargoholds are full by psykers put into artificial sleep. Unfortunately, arcane security systems have weakend and psyker’s collective nightmares begin to manifest aboard.
47 This Ordo Xenos ship once carried numerous dangerous xenos for interragation or research in its stasis chambers. Good news – those organisms could help the holy Inquisition if safely delivered. Bad news – ship will not be able to keep stasis chambers online for much longer. Very bad news – some of the chambers are already offline and open.
48 Ship and crew are fine, and living angels of emperor’s wrath are welcomed aboard as honoured guests. But the ship was supposed to be lost to the warp and auspex readings show it has been navigating the warp with its Gellar fields offline.
49 Ship is empty, unmanned and unpowered, but something is blocking the auspex trying to investigate its insides and after a few days of walking through the decks it becomes clear that ship is much larger inside than it is from outside.
50 Entrenching servitors turned this ship into bastion filled with razor-wire, mines and sentry turrets of all kinds. The main cogitator, which can shut the defences down is located in the most secured hold reserved for very important cargo – who knows what relics are there with it?
51 Grey Knights space marine in a state of self-induced coma holds a huge ancsient tome. Servo-joints of his suit of armour are deliberately jammed in a way which looks like prevents the book from opening itself.
52 Micro-meteor bombardment- tiny rocks travelling at high enough velocity to punch through hull sections (and armour).
53 A ship’s reactor has ‘melted down’, burning through it’s containment and it is now slowly melting a path through the space hulk.
54 Corrupted servitors. The Emperor Protects has stats for these- or you could go crazy with a giant ‘forklift’ servitor running amok…
55 Compromised integrity- a section of the ’hulk starts to break apart. Or the other way around- centrifugal force/gravity anomalies cause a section of the ’hulk to start compacting.
  1. A grim hiveworld with…
1 Lake filled with liquid toxic waste. Possibly partly frozen enough to allow walking on its surface (consider icy surface a dangerous terrain) but falling, jumping or using explosives on thin solid surface is just asking for trouble.
2 Some 250 levels above people throw their solid waste (from paper and plastic to sharpened metal rods and heavy machinery parts) bombarding this part of an underhive.
3 1+2 combined – brace yourself for some toxic tsunamis and corrosive splashes
4 This level consists of many layers of metal scrap, and its structure is not stable enough to walk safely in all places.
5 Toppled spire which was an Imperial shrine now works as a road sign for underhive-dwellers
6 This vast level is a labyrinth of hab-blocks, tunnels, passages and deadends. People living here speak their own dialect unknown to outsiders and use cheap trinkets like nails, cogs, coins and shards of glass for maps, signs and markins. 
7 Underhive scum-gang leaders play “nobility” and rule their “vassals”. Nobody has ever seen a member of actual imperial authority in their lifetime.
8 Mutants
9 Cult of Redemption incineration teams.
10 8+9, they fight each other and literally anyone who interferes.
11 Ghost-level. Something forced the inhabitants of those fairly comfortable hab-blocks, hospitals, schools and manufactoria to abandon them and people living above and below this level, while living in much worse conditions, are afraid even to speak about this level.
12 A common market where cease-fire for everyone is enforced.
13 Archeotech or xenotech relics. Their condition varies, but in any condition they are enogh to get killed for.
14 Spireborn nobility armed to the teeth and guarded by small group of House Guards just in case went down here to entertain themselves with a man-hunt.
15 Unremarkable hab-block harbouring a well-conseald shrine to the Dark Gods.
16 Rogue psyker and witch-hunters pursuing him.
17 A unique miracle – real, living fruit tree, zealously guarded by locals. Legend says, a Space Marine rested under this tree before moving on to liberate the planet. Fruits of this tree cost a no small fortune – probably because tree is watered by blood of those who dare touch it.
18 Second son of an imperial noble for some reason gathers himself a force of gangers, mercenaries, cut-throats and other low-life scum. Optionally – agents of the first son watching his every step.
19 Treasury of a long-forgotten noble family which looks so out of place, especially when used as a tothem for feral tribe inhabitating this level.
20 This hab-block is a living place of an old man, one of the rare few guardsmen who got decomissioned. After his long years of service he has a lifetime of stories to tell and a trophy – claw, formerly belongig to huge ork warboss. Green moss growing around his hab-cell looks… like your average moss, I guess?
21 Virulent plague infests this level, and it is home to mad prophets, flagellants, dead and dying.
22 21, but with Plague zombies.
23 Local gang-lords play Carmageddon for real with killer-cars on those lawless streets.
24 Necron tomb. Admit it, you expected that.
25 Anscient reactor, maintained by degraded ancestors of its former personnel. It feeds nothing and produces motly only excessive heat, but can be used to help with power supply issues on higher levels.
26 Remnants of STC, robbed long ago but still valuable to local Omnissiah cult.
27 Beautiful altar of Emperor and Horus… drinking wine together with their fellow space marines.
28 Here demon worship, orgies, forbidden experiments, cold trade, slave trade, gladiator matches, chaos rituals and jaywalking take place.
29 Dead forest covered by huge glass hemishphere
30 Local Adeptus Mechanicus Inner Circle data-network access terminal.
31 A small settlement surviving with anything they can find in a huge scrapheap which spans as far as eye can see across them.
32 Anchient void capital ship. Buried, but still salvageble. Of course, to add this relic to sector battlefleet battleship reserve you will have to get rid of no small part of the hive with everyone living there.
33 A small outpost belonging to one of the hive’s Noble Houses, exceptionally well guarded and set to self-destruct in case of confirmed security breach. What could they be hiding there?
34 Ruins of another hive, on top of which current hive was built. And they are still inhabitated.
35 Dead space marine, along with weapons and power armour, and with no visible physical damage.
36 Dead chaos space marine, along with weapons and power armour, and with no visible physical damage.
37 Suspicious merchant eager to sell “Real Adeptus Sororitas boltgun bolt casings! Best trinket against the tainted and the wicked!”
38 Abandoned warehouse, guarded by combat servitors. Some of them are still functional and following murder-protocols.
39 Due to chartist cargoship getting late underhive is filled with cannibals and corpses of those dead from starvation.
40 Someone deliberately poisoned underhive’s water supply, turning this part of the hive into impossibly large graveyard.
41 Geothermal shaft to the planet’s core. Its maintainance elevators could be used to get to any level in the hive without drawing attention.
42 2 companies of PDF were sent there to deal with an underhive chaos cult, and both are confident that another company succumbed to corruption.
43 Armoured column of gun-trucks, IFV’s and warbikes belonging to some underhive merchant guild is willing to make trade with anyone. They carry weapons, supplies and child slaves.
44 This whole level is filled with promethium holders. Try not to make it go kaboom.
45 Two inquisitorial acolyte teams fighting each other, both are secretive about what they are looking for and why do they fight each other.
46 Archeological team who is dwelling probably a bit too deep into planet’s history.
47 Corrupt Arbites enforcers cleared this level of gangsters but now commit even worse atrocities.
48 Rad-mines. This place is so deadly even guards are sent here to atone for something, and the only way to get out is to increase production output. Life expectancy here is short, and press-gangs lurking in neighbouring levels are eager to clutch anyone unlucky enough.
49 Small abhuman ghetto.
50 Rogue trader explorator team making their escape from even lower levels of underhive with extreme haste. They don’t have time to stop by and tell you what exactly are they running from.
