Underland Citadels - Celebrating Post #600

Celebrating 600 posts here on the blog that time forgot. When I did my Psychon citadels I considered they would be possible in a fantasy setting and my Underland came to mind as a way to use them. I had my first visions of a post fantasy apocalypse setting I have finally began to use and develop. Sauron a bit to blame too. Found a bunch of Barlow art that really looks like my Underland (only a bit more colourful as I envisaged ash as main colour and since i started using design markers my palette has become softer). Perhaps some kind wonderful person will automate this set of tables for me. Ill write a d100 on anything for person who does (though a d100 inalienable rights of women's agency in Gor setting - might be too hard unfortunately).

Original citadels for psychon - please ignore sentence that reads "muscle or steak powered elevators"

These are Psychon Citadel Silhouettes - I will do some Underland ones - also good spaceships
http://elfmaidsandoctopi.blogspot.com.au/2014/01/psychon-citadel-silhouettes.html
This was also first attempt at making a fantasy citadel with what i had in tables already
Also for Psychon fans lots of public holidays next year so will do a few days of Psychon play. Might try and revise the Psychon PDF this hols too.

The main difference is removal of references to technology, psionics, androids, morlocks and automation. The power plant section was removed entirely. Surface and crowning features have been changed most.

Monster murder machines post has lots of things that could be useful to include in a citadel elfmaidsandoctopi.blogspot.com.au/2014/09/1d100-magic-monster-machines-for-your.html

Citadel Generation
These are to help you generate citadels which should inspire plenty of adventure for many sessions of play. In the underland citadels, ruins, horrible wastelands and remnants of great monster machines of ancient wars are the most dramatic features. Citadels in Underland tend to be semi abandoned with mostly bottom floors inhabited and unaware of upper floors or life there. Exploring citadels is a common quest. References to habitation in random locations can be referring to original function and now could be abandoned.

Locations in citadels
You could allocate locations you think your citadel needs first and roll extra or roll them all. Location sub tables are merely standout features of otherwise typical features in citadel planning. Sub levels and ground floor may have multiple section per level but most others equal a floor or story. Low tech citadels use muscle or steam or magic powered elevators or stairs with elevators and even gravity tubes for more advanced. Not all locations are as specialised as sub tables show so feel free to use more generic areas or develop your own or hybrid results.

Citadel Habitation 1 (1d4) this indicates how inhabited by any semblance of civilisation
Citadel surrounds 1d3 this is the surrounding countryside
Citadel Surface 1d3 this is the actual skin of the citadel
Additional Features 1d3 these are other interesting local phenomena and adventure ideas
Event 1 this is something to happen when adventurers turn up to get adventure rolling

Sub levels 1d4+1 You may assume catacombs, cisterns or storage and roll rest
Ground floors 1d4+2 You may assume a gatehouse and roll rest
Mid levels 6d6 You may assume a ghetto or middle housing and roll rest
Upper levels 1d12 You may assume a palace for rulers and roll rest
Crowning feature 1 is a object on top for some function

Basic details of a citadel:
Surface and surrounding area features


d12 Citadel Habitation
Use this to populate a citadel. If you want one defiantly inhabited roll other dice like d8+4 d6+6. You could alternatively roll for different sections of the citadel like lower or mid levels by rolling a d4 times on he below table to generate areas ruled by a faction or many or none.

d12 Citadel surface
Most citadels are highly ornamental with spires, towers, statues, gargoyles and and other ornaments. Here are some common variations. Many seem to merge with the ceiling of great chasms but this might be an illusion.

1 Defences bristling with battlements, turrets, guns, towers, observation posts and guards
2 Fungus and algae and slime coated with dripping water and stagnant pools, attracts many creatures

D100 Citadel Events 
This is to be used by adventurers staying in the citadel foreign and mercantile quarters. I have done this in a way to be usable in other settings too. Handy to have a event ready for visitors. Citadel events imply a faction operates as a community like a town but if all ruined use dungeon tables. Often citadels have many factions separated by ruins, some are unaware of each other.

Citadel Locations

D12 Citadel  Zones - Lower Level
These levels deal with the outside world the most and are bristling with arrow slits, gunports, turrets, gates, battlements and weapons. The heavy fortress defences are heavily patrolled and separate gates for locals and foreigners are normal.

1-3 Defence
4-5 Merchant
6-7 Foreign
8-9 Craft
10-12 Ghetto

D12 Citadel  Zones - Mid Level
These levels are the basic living areas of the bulk of the population and industry that keep citadel alive. Less accessible to outsiders some citizens never leave this area.

1 Merchant
2 Church
3 Library
4-5 Farm
6-7 Craft
8 Ghetto
9-11 Middle Housing
12 Stadium

D12 Citadel  Zones - Upper Level 
These levels are for the elites and rulers of the citadel often forbidden to lower residence. Foriegn diplomats or great heroes or merchants may be welcomed.

1-2 Middle Housing
3-4 Church
5 Library
6 University
7 Museum
8 Stadium
9 Garden
10 Merchant
11-12 Palace
 
D12 Citadel  Zones - Sub Level
Underworld levels are hidden areas often with dangerous or unappealing places best kept out of sight. They are prone to being forgotten and even may have other populations or creatures dwelling in them. Most citizens think sub levels are dangerous and unpleasant.

1 Cistern
2 Mine
3-4 Catacombs
5 Garden
6 Farm
7 Shelter
8 Storage
9 Ghetto
10 Transit Tunnels
11-12 Dungeon
 
d12 Catacombs
These ancient tunnels have had various uses and are a maze of mostly roughly hewn and seldom used. Storage of the dead and occasional hiding place is what most locals think. Usually spooky, dank and unwelcoming. May be far more ancient than citadel or apocalypse. 

1 Niches with skeletons
2 Niches with coffins
3 Piles of bones often arranged in macabre stacks
4 Bundles of human remains
5 Mummified bodies in niches
6 Artwork depicting gloomy afterlife
7 Graffiti some very ancient
8 Insignia and shrines of long lost or hidden cult
9 Signs of habitation by criminal gang
10 lair of some kind of monster that has found a home here
11 Signs of a sweatshop
12 Stone sarcophagi
 
d12 Church
Temples are used but people to worship gods in most cases but could include shrines to ancestors, the state, the rulers, abstract philosophical concepts. Some may have specific roles and clientele. The popular faiths are part of the civilization but fringe, foriegn and forbidden ones possible too.

1 A tiny shrine with idols, simple stone slab altar or artwork in a niche or small room
2 A small church with room for a dozen worshipers and accommodation for holy teacher
3 A temple with room for up to a hundred worshipers and several staff
4 A cathedral with room for up to a thousand with many chambers, staff and artworks
5 An abandoned shrine to a long lost cult mostly dust covered
6 A hidden shrine with disguised entrance to secret cult chamber
7 A shrine which acts as a place of healing
8 A mausoleum with hundreds of interred dead and a chapel
9 A monumental scale work of devotional artwork such as a huge statue or stained glass
10 An oracle where locals come for divination, prophecy and advice
11 Monastery or nunnery where devotees live lives of simplicity and contemplation
12 A fully functional temple where holy folk commune with a god with holy guardians

d12 Cistern
This is usually simply for water storage but also includes waste and sewerage possibilities. Most have water stores or wells and sewerage but these represent larger more efficient functioning examples.

1 Huge vaulted water supply of good water with many chambers connected by arched tunnels
2 A maze of sub canals with dock with boats used for transport
3 Huge wells going deep into subterranean water filled caverns and waterways
4 Chambers with underground springs and crystal deposits
5 Spectacular ancient bathhouse with steam rooms and swimming pools
6 Fungus garden of exotic narcotic and edible stuff lit by dim phosphorescent glow
7 Huge cisterns full of sewerage, possibly flammable gas and unwelcome creatures
8 Sewer tunnel complex like a nightmare maze crawling with critters
9 Water treatment area where contaminated water stored and filtered
10 Slime encrusted grotto overgrown with strange growths from tainted water
11 Garbage filled cistern filled with citadel trash and drain water and sewerage
12 Lair of someone or something uses water for secret movement beneath citadel

d12 Craft
A centre for making goods and refining materials. Provide work as well as luxury, trade goods and weapons. More industry equals more work.

1 Huge sweatshops where workers sleep and work for life
2 Industrial factory with rows of workers tending machines in unison
3 Automaton assembly lines with golem workers in sealed system
4 Great guild halls of specialist craftsmen trade and meet to discuss trade restrictions and licenses
5 Huge smelting facility with workers toiling in horrendous heat
6 Huge workshop with separate cottage craftsmen skilfully making goods
7 Docile subhumans bred or lobotomized or charmed for compliant labour in sweatshop
8 Shoggoths imprisoned in great vaults working on all manner of goods
9 Huge mills with children scuttling among deadly spinning apparatus
10 Animals or slaves turning huge wheels powering mills
11 Gremlins, gnomes, dwarves or goblins bound in sweatshop with enchantment
12 Steaming factory powered by torture apparatus with prisoners screaming in pain  

d12 Defence
These are to defend city from invaders and often manned by soldiers, police, agents or militia. They are usually serious places and unwelcome to visitors. Most citadels have most of these especially a front gate but subtable results equal far more examples than needed.

1 Guardhouses everywhere to police area, often with view of outside and alarm device.
2 Gatehouses with massive doorways and mechanisms possibly murder holes and traps
3 Lockup or stocks where vagrants and miscreants and enemies are temporarily detained
4 Observation towers with view of outside or a district with communications of some kind
5 Recruiting centres where new troops are trained and drilled and drafted from populace

10 Martial art school where some specialist school of fighters train under a master
11 Training area with firing range, commando course, test dummies and other aids
12 Stables for mobile defence forces

d12 Dungeon
Intended as a grim place of imprisonment may include areas abandoned to unwelcome creatures and persons having overtaken abandoned areas. Most regard with fear and trepidation. Most have at least some cells if not dedicated high population facility. Banishment or execution is a lot less effort and cheaper.

1 A huge prison with cells, work yards and security gates and barracks
2 A huge maze of torture equipment and cells with imprisoned victims in appalling conditions
3 A mental hospital where mentally ill are kept in despairing conditions
4 A hospital where deformed, disfigured, disabled and mutants are kept in horrible conditions

9 Overrun by creatures and monsters of all sorts and long abandoned by citadel residents
10 A hidden complex of cultist kidnappers sacrificing citizens in secret
11 Humanoids like goblins or kobolds have taken over area as a homeland
12 Heavily sealed and trapped, something sealed in here best forgotten long ago

d12 Farm
These areas provide food, requiring natural light, artificial life or crops that do not require light like fungi. Citadel may have outside crops too if terrain not harsh, indoor farms do better. Without these food is more costly, boring and scarce. Trade can provide some food in bad cases but food shortages tend to shrink the population.

1 Monoculture of single crop with specialized tools and chemicals and labour
2 Mixed gardens with many variety of crops and animals
3 Eco garden which appears wild and unkept but is a thriving ecosystem
4 Hydro garden with crops grown in water on rafts, possibly aquaculture like fish underneath
5 Aquaculture farm with fish, insect larvae, frogs, eels, lampreys and shellfish grown in tanks
6 Bug farm with insect and larvae farming, often low maintenance
7 Wild greenhouse of savage ecology mobile plants or fungi

9 Often secret facility where intelligent slaves are bred or kept for giant abattoir
10 Overgrown with toxic slimes and fungus and inhabited by unwelcome creatures
11 Culture farm where huge vats of bacteria and yeast and algae bubble constantly
12 Cattle or livestock or other animals graze on fungus or vegetation under artificial lights
 
d12 Foreign
This is where outsiders who visit for trade and diplomacy come to do business with citadel occupants without the citadel being contaminated. Aliens are usually documented and given passports for duration of stay and are often unwelcome outside this area or given limited access beyond. Only local merchants and brave locals mingle with foreigners. Some cities are more tolerant of foreigners living among them, others dont even let them inside. Dedicated foreign districts mean more trade and tolerance.

1 Embassy where a foreign power officials dwell for international affairs
2 Enclave where outsider culture practice own way of life, microcosm of foreign culture
3 Inns where foreigners stay while visiting often in groups for guests of varied status
4 Taverns where foreigners and locals mingle over food and drink
5 Brothels where exotic prostitutes cater to tastes of many lands
6 Custom house where foreigners are registered and taxed
7 Quarantine hospice where diseased or those suspected of disease are kept
8 Schoolhouse where languages and customs of citadel or other lands are taught
9 Zoo where foreign beasts are kept for amusement or out of suspicion
10 Fairgrounds where travelling carny and circuses set up their seedy excuses for fun
11 Slavemarkets where foreigners can be bought and sold
12 Warehouses of foreign goods are stored

d12 Garden
A place of recreation, beauty and education to be enjoyed by better class of citizens. Some places prefer fungus gardens, especially if underground. Gardens are for recreation and science rather than feeding a whole community.

1 Pleasure garden with scented edible plants, narcotics and roaming prostitutes
2 Herbalist garden where scholars, cooks, pharmacists and herbalists grow exotic supplies
3 Drug crops often guarded and exclusive to elites or sect
4 Sporting green for games and competitions of all kinds with snack stalls
5 Children’s park where kids and carers frolic with harmless creatures and gentle trees
6 Botanical park where plants of many lands are kept for educational purposes
7 Zoological park where beasts many lands are kept for educational purposes
8 Lovers park where youths come for holding hands and other liaisons
9 Fairground park with extravagant entertainment, rides, stalls, clowns and other fun
10 Abandoned park gone feral with unwelcome beasts and gangland fights
11 Royal park where elites only frolic amidst tasteful decor and artwork
12 Water park with streams, ponds, thermal springs and exotic fish in tanks 

d12 Ghetto
These areas are dwellings of poorest, often overcrowded, dangerous, polluted and miserable. Some are a different race or ethnic group to typical citizens. Some citadels have no poor classes. In others the poor are expendable slaves.

1 Orderly worker barracks where dwellers shuffle of despairing to workshops daily
2 Cottage crafters where dwellers operate light industry and sleep among workbenches
3 Crime filled gang turf neighborhood where lawmen and other services avoid
4 Horrible area with decaying buildings and disease ridden starving inhabitants
5 Old neighborhood with mostly geriatric population few young desperate to escape from
6 Open gang war with kidnapping, murder, extortion and frequent brawls
7 Controlled by local gang who charge tax and act as officials and run best black markets
8 Powder keg of dissent with revolutionaries and demagogues driving people to boiling point
9 Cruel police suppress this area due to constant riots. Brutality drive resistance underground
10 Fire trap frequently redeveloped and rebuilt with new fires common
11 Rebuilt by well meaning officials but flawed and already in decay
