A-Z Ruins of Planet Psychon

Ruins are a pretty common feature on any hex in Psychon. This is to help adlib and speed up the process of making ruins. Just like the gods of Psychon do all the time. Do remember these ruins could be victorian, deco-jazz age, 50s, 21st C or more advanced or even inconsistent. Civilizations have risen and fallen for aeons or faked a week ago by a god who just like ruins. For less tech stuff try some of my other a-z or table books.

A Alien
It is possible that aliens might visit Psychon but it is more likely that the gods are just faking aliens or some one has returned from the stars after centuries away. Alien locations tend to offer strange technology, ruins and dead bodies. Living alien creatures or machines might be here also. Such places are dangerous and often taboo to locals. 

1 Crashed flying saucer with ancient grey skinned space eldren corpses and some tech
2 Crude shelter where crashed space travellers lived for several years scrawling messages before deaths
3 Elderly space traveller living in ship wreck warns about horrors from the stars 
4 Wrecked orbital populated by adressive robot survivors and a uplink terminal to one of the AI gods

6 Crashed ship with broken cages. A horrible monster from the stars or orbital gene lab lives here 
7 A forcefield and holographic shielded area where alien observers watch the outside world
8 Cyborg clone troops deployed from cryonic storage in orbit arrived bit too late for the apocalypse
9 Scout craft for race of hostile brain borgs who have returned from the stars and seek to terraform the earth for their new need that would kill all current life
10 Eldren shuttle parked here while xplorers gather goods needed for their orbital station

B Bunker
Many complexes are buried beneath Psychon some predating he apocalypse. Though the gods are not above creating a ruined bunker with long histories and populations. Some are very ancient but once opened the population will be modified by nanite swarms to be natives of Planet Psychon. Some bunkers are specialised in some function. Others were overrun by hostile savages, monsters or undead aeons ago. They are famous for intact technology but some were build more recently by collapsing civilizations. Some are overgrown with fungus or tree roots or other organic matter. Some were defective and fell victim to life support failure or mutation or biological weapons. Some act as thriving settlements and trade but often don't let strangers inside. 

1 Sealed and populated by ancients uncontaminated by elements of Planet Psychon
2 Secured population act as a trading post, some sections might be abandoned
3 Corroded and even burned, occupied by undead and other monsters but some loot4 Overgrown with fungus, tree roots or vegetation with feral animals inside
5 Population are mutated cultists hungry for flesh and depravity 
6 Has been resettled by scavengers and is littered in junk and garbage 
7 Occupied by robots and androids most often not welcoming to humans but in good repair 
8 Semi ruined bunker occupied by a gang, cult or secret society
9 Biological mutant growths have covered everything in organic matter and is home to creatures
10 Sealed survivalist bunker with cryonics freezers for humans and DNA and equipment to repopulate the world

C Crossing
A location with some obstacle or barrier to travel. Often just difficult or has a toll or crew required to operate like a ferryman or drawbridge. Some more curious barriers might require a moral challenge or a test when operated by a sphynx or wizard or a god.

1 Gaping chasm with a rickety old rope and plank bridge with flimsy rope handhold and some kind of guardian
2 Flooded chasm with water cascading indo deeps, something lurks in the water

6 A portcullis gate with guards who don't want to let anyone through without a valuable gift
7 Trolls guarding a crude stone wall with a open gate want food to pass
8 Forcefield or energy screen barrier blocks the path, an AI is rude to anyone wanting passage
9 Wall of magical fire with a magic mouth that warns intruders to stay away (could be cold or electric arc)
10 Minefield covers area possibly a warning sign or corpses and craters as a warning

D Dungeon
Dungeons are more primitive than bunkers, typically sub ground levels in a ruined castle or fort used as a miserable place of imprisonment. Many such complexes become overrun by monsters of all sorts who set up multiple lairs. Sometimes a boss monster becomes a leader of the dungeon and begins raiding outsiders. Some dungeons go deeper or might connect to other subterranean passages, caves or bunker complexes. Dungeons are a principal way for adventurers to get treasure. Other unsavoury types often inhabit dungeons or just wild creatures looking for a home. It is rare to find a truly empty one.

1 A ruined castle with a grim open gateway. Crumbling stone labyrinth once a prison now inhabited by humanoids and monsters

9 Abandoned underground prison where a cult worship the great old ones and bring sacrifices
10 Remains of ancient boiler room filled with garbage where desperate survivors hide from the monsters they also share

E Educational
These facilities were schools of various types used by the ancients. Some are for children or teens, some for adult vocational or academic. Some cultures produced schools for magic or psionics or other strange arts. Even strange cults operate schools but often they will have some kind of front or cover. A few schools are run by AIs and are possibly dangerously delusional. Some are homes of feral children or youth gangs.

1 Kindergarten operated by nanny bots who are desperate for victims to feed and burp and put nappies on
2 Primary School where some well meaning being teaches local children skills to survive on Psychon like read ancient

9 School is a front for cultists worshiping some vile evil god in secret 
10 Fighting school where students study martial arts or sword fighting

F Factory
These ancient manufacturing plants are very common in ruined cities. Some are automated by robots, others low tech machine shops and boilers or even archaic sweatshops. Various types of factories depend on what kind of goods are made. Power plants, smelters, foundries, refineries are heavy typical industry. Food, cars, appliances and other more personal goods are common too. Such places are good for raw materials and industrial loot. Many are stripped bare and choked in rust. Looters are fond of searching them for scrap or raw materials.

10 Sealed autofactory with robot guards and a forcefield. The AI might be willing to trade raw materials or to get rid of organic life infesting the complex

G Garden
A area rich in vegetation including parks, greenhouses, agricultural complexes and other forms of mostly plants. Some areas also attracted animals or even were zoological gardens. All kinds of life forms and hunters are atracted and some have guardians who care for the location. Some are fenced off or enclosed under glass or a dome. Some have thriving ecologies. Whatever the case rich life attracts more life and encounters.

1 Domed structure rich in plants and animals, often mutated and hostile. An AI takes care of the complex and operates several robots
2 Huge wrought iron and glass green house complex thick with vegetation. Plant abhumans dwell here who have mobile plant pets and hate animal life they grind up to fertilise soil

K Shopping
These ruins are former retail places. Can vary from small stores to supermarkets to malls. Some still operate in some form. Synthetic staff might think it is business as usual. Someone might have re opened it as a store or a marketplace. Some gain colourful names from locals like murdermart, killco, deathmall. As premier loot places they attract all kinds of scavengers and scum.

M Medical
This can vary from a full fledged hospital to a medical centre or a doctors office. Sometimes a healer sets up shop in the ruins to treat the wounded. Some medical facilities are more for research and are still secure or might contain hazardous materials. Loot includes medical supplies so such locations are popular to loot. A tribe might aggressively occupy such a place or regard it as a holy place.

1 Small medical clinic building mostly stripped but has a safe and some monster using as a lair

Often archaic stone buildings with columns and ancient decor or crumbling modern complexes. Often feature statues and government signage. Some might be guarded by synthetics or inhabited by cults who believe they can establish the old order. Often full of records and ruined computers, many are fire damaged. Some have become libraries dedicated to collecting information about the past established by well meaning secret societies. Some gangs occupy these for the sense they represent authority.

O Organic
Living biological structures have various origins. Ancients and gods have experimented with organic buildings that even feed the inhabitants and grow extra chambers as needed. Sometimes some poor mutant thing becomes so massive it cannot move or even be recognised. Some creatures build semi organic structures using secretions. Such places might be disgusting and are definitely inhabited.
1 Giant termite like mounds made of spittle and rubble towering like ancient buildings
2 Huge waxy hexagon structured hive for bee or wasp like creatures or peoples

T Temple
Many in the ruins are deeply religious and the various AI gods often operate temples in ruined zones as it is a good place to recruit desperate worshipers. These are good places to get healing or missions just don't pick the wrong cult. Priests often can provide advice and can be grateful for help with cult goals. Many cults fight so most are well defended. A god might intervene in some cases bringing orbital weapons or teleporting guardians into place. Weaker gods rely on fanatic cultists and pets.

X Black Lab
All kinds of labs existed in the past but black labs seem to survive better due to danger and security. Many are in good condition. Not all are involved in amoral evil projects but people lump all ancient tech in with black science at times. Some cults are atracted to them and temples and other parties often send explorers on missions to them. Some lone mad scientists might set up a crude lab but they can only go so far compared to these complexes

1 Concrete bunker guarded by robots, inside are dead scientists and a AI working on a new doomsday bio weapon
2 Black glass complex guarded by a forcefield. If breached there are android guards and a AI working on mind control. Prisoners are in cells inside being tested

10 Theme park biolab complex where AI created dinosaurs and pleistocene mammals to release for research

Y Transit Hub
These represent large scale transport infrastructure on the surface to facilitate transport. It includes airports, monorail lines, airship mooring towers, elevated highways, harbours and other transport. Water based ones might be landlocked after time goes by or choked in vegetation. As some of these are huge expect multiple factions and types of monsters

1 Airport with huge buildings, hangars and crashed aircraft often with feuding factions
2 Airship mooring possibly with huge hangers and wrecks of airships
3 Monorail line with stations and wrecked trains draped over terrain and rubble
4 Elevated roads often hard to reach from ground with wrecked cars. Some settle them and install lifts and bring up dirt to farm away from ground threats 
5 Major crossroads of multiple highways possibly with footbridge or underpass, some with elevated or underground lanes. Encounters are common here
6 Aqueduct once transported water, often dry but might have living fish 
7 Harbour with jetties, boat sheds and wrecked boats possibly land locked
8 Bus depot with building and dozens of wrecked busses often make a good camp
9 Canal possibly dried or overgrown with boats and ships rusting away. Each boat could be a lair or gang camp
10 Spaceport with shuttle craft and terminal structure, often these have been damages by warfare or explosions from crashes or liftoff disasters. often with a funcional AI or com link to a orbital

Z Burial ground
The ancients buried their dead. Some cultures included grave goods and jewelry but most shun such places. Obviously undead proliferate in such places. Some are simple graveyards others massive mausoleums.
