Worlds of the Prosperitas Sector

Subsector Primus

Asteroid 24334-1: Satellite Colony. A luxurious asteroid colony known to its residents at Cyprus Creek, it is the seat of the Chartist House Globex.

Carthusia: Civilised World. A wet, humid planet with a high water table, it is a prosperous Imperial world favoured as a tourist destination by the wealthy of Subsector Primus.

Castellum: Forge World. Formerly a break-away colony of Forge Ferraeus, Castellum was invaded in 4-134.598.M41 and annexed by Ferraeus becoming a dominion of the Forge and ending its independence.

Duroverum: Hive World. Designated as the Capital of the Prosperitas Sector, it is the seat of Imperial Governance.

Ferraeus: Forge World. Taken from Hereteks early in the Prosperitas Crusade, it is the victim of millennia of pollution that has made the air toxic and forced its inhabitants to live their lives in environment suits.

Gaudium: Hive World. Once a thriving and beautiful Shrine World, it is now an overpopulated and sprawling mass of hive cities spreading across a barren and treacherous coastline.

Korimesta: Penal World. One of the oldest planets in the sector, it was once a hub of trade. Now it is an idol of fallen splendour. Following a failed rebellion the world now serves as a penal world for its population who have been sentenced to labour for the Imperium.

Kydos: Agri-World. A small, dense world covered in phenomenally deep planetary oceans, which support a vast range of flora and fauna.

Letifer Secundus: Hive World. A poisonous wasteland dotted with atmo-sealed hives, it was once a refugee colony. In recent years it has become the home of the heart of the sector’s narcotics industry.

Mazar-63: Satellite Colony. A tunnel-honeycombed, hollow moon around a sterile planet, it is the seat of Noble House Roshan-Fikran.

Merewald: Feudal World. A world of few natural threats and a generally warm, equable climate suitable for cultivation. Its population is spread widely, with few towns and no cities as such: most of the inhabitants are peasants, ruled from the castles and palaces of the Noble Houses.

Midsummer: Agri-World. A world abundant with natural life, and the breadbasket of the Prosperitas Sector, Midsummer is home to a strange and insular group of colonists who follow a divergent sect of the Imperial Cult known as the 'Harvest Cult' who base their worship of the Emperor around nature.

Monacus: Hive World. A rich and crowded world, serving as a popular tourist destination for the wealthy youth of Subsector Primus due to its uphive clubs catering to pleasures of all kinds.

Nivalis: Shrine World (disputed). Previously a pristine world, its mountains carved with the likenesses of Heroes of the Imperium, its uncountable temples and shrines have been wrecked by the bombardment of the Archenemy and civil strife during the Temple uprising.

Persephon IV: War World. Having born the brunt of the savage greenskins of Waagh!! Gazbag since 531.M41, much of its original glory has been ravaged by the Orks. Its people fight an endless war in order to ensure that the greenskin menace is contained there.

Strayvia: Dead World. A former agri-world, it was devastated by Exterminatus virus-bombs in 577.M41, leaving the Strayvian Regiments homeless and embittered.

St Sebastian’s Redoubt: Space Station. Once home to a heretic order, the station was cleansed by the Ministorum and turned into a holy place of education. The gothic spires of this asteroid fortress house both a Schola Progenium and a Ministorum Seminary, but still hide many secrets.

Subsector Secundus

Anaximund Alpha: Non-Compliant Knight World. The only known Knight World of the sector, its sole duty is to feed the worker population of Naximus Prime. Its rulers, House Qureshi, have ridden their war engines to the defence of the Mechanicus and the Imperium on many occasions, though only ever with the blessings of its Forge World patron.

Caracas: Feral World. A world where the majority of the population are nomadic tribespeople, it is covered mostly in dense forest in the equatorial and tropical regions, with tundra towards the poles. It is valued solely for its hardy human and abhuman population.

Caudica Secundus: Dead World. A former hive world, it originally prospered as a profitable mining world. Its biosphere was eradicated due to Exterminatus in late 582.M41, though some of the population was evacuated as the Caudican Diaspora.

Everholt: Quarantined World. A heavily forested former agri-world known for its lumber exports, it rose up against the Imperium in 586.M41. This led to the planet's interdiction and quarantine.

Finisterra: Non-Compliant World. A non-Imperial world beyond the boundaries of Imperial Space, it is the site of a humiliating defeat for the Imperium in 592.M41. The local human population, the 'Esa', successfully drove off an Imperial Expeditionary Force despite being technologically inferior to the Imperium, and has so far resisted conquest. Said to be under protection of the Lions of Nemea.

Helaerus III: Hive World. A hellish, temperate death world forest covers the surface of the planet, though the population live inside several dozen hives.

Henlock: War World. Currently held by the forces of the Archenemy, it was formerly an Adeptus Mechanicus world, valued for its Titan training grounds and ancient Heresy-era Titan Graveyard. When Archenemy forces took the world in 538.M41, a desperate counter-attack by the Imperium led to a disaster that cost the life of the Warmaster of the Prosperitas Crusade.

Kirkcud III: Civilised World. A wild and newly-developed haven, it is heavily wooded and perfect for settlement, but dogged by rumblings of non-compliance from a stubborn local population and recurrent attacks from Archenemy forces.

Lerwick: Civilised World. A desolate and arctic oceanic planet, it is heavily defended from orbit. It lies at a strategically vital location on the Rimward edge of the Trade Spine and is on the frontier of Regency assaults.

Macharion CDXI: Frontier World. The sector’s most recent colony, it is a dry and dusty world in the early stages of Imperial colonisation that so far has shown promise.

Mawson’s Wake: Frontier World. At the Rimward edge of the sector, and a patchily-inhabited, struggling frontier planet with a history of revolt. Largely desertified and scarred by open-cast mining, the Wake ekes out an existence dependent on an ancient vehicle manufactorum, and pays its tithe with conscripts from among the resentful populace.

Naximus Prime: Non-Compliant Forge World. Rediscovered in 401.M41, it is not welcoming to the Imperium. Rigidly independent, its Forges accept Imperial work-orders, but do so at their own discretion. The three Temple-Moons of the planet serve as heavily-armed defences to the system.

Olethros Secunda: Archenemy Held World. A third generation colony world, the planet was settled with the help of a substantial grant of sacred technology from the Adeptus Mechanicus of Naximus Prime. Invaded in 594.M41 by the Archenemy of the Regency and currently under their control.

Shadowglow: Death World. Shrouded in near-permanent darkness by a complex lunar cycle, it is a freezing, inhospitable desert world. The planet is home to a race of abhumans known as 'Raivans', whose fanatical loyalty to the Imperial Cult, combined with superior strength and speed, make the world a fertile recruiting ground for the Crusade.

Vallum: Fortress World. On the far Coreward-Spinward corner of the subsector, the it stands as the lonely guardian of the final approach to the area around Polarnus Station.

Subsector Tertius

Agrial III: Shrine World. An ancient world covered in dusty sepulchres and echoing chapels, it is a seldom-mentioned backwater planet that contains what is possibly one of the largest libraries in all of Segmentum Obscurus. Recovering from bloody civil strife in the wake of the Temple uprising.

Amenophis IV: Hive World. An old, desert planet on the Tenebris border, with a series of industrial hive cities and some impressive ruins.

Bachian IV: Industrial World. A mining outpost with a highly toxic atmosphere, controlled by House Vilas-Lobo.

Burisalis Prime: Civilised World. At a comfortable distance from a stable star, it is a temperate world of gentle, sweeping plains. It is used primarily by the sector’s Imperial Guard as a training ground for armoured and artillery regiments.

Butonia: Feudal World. Conquered for its carbon-3 deposits, the majority of the planet is a feudal, low-advancement society, though its capital and Noble Houses are reaching Imperial-levels of technology thanks to the world's mining efforts.

Kuatis: Industrial World. Focused on shipbuilding, and dominated by guilds and the Imperial Navy, it is controlled as a naval fiefdom. Smog and near-constant sheeting rain obscure starlight, while tunnels run across the surface between settlements to protect those that can afford to pass through them from the miserable environment.

Kelper Prime: Archenemy Held World. Once heavily fortified Fortress World on the Tenebris border, Kelper Prime controlled one of the main Warp routes into Subsector Tertius. Crusade forces were recently routed by the forces of the Archenemy from here.

Lubyanka: Penal World. The surface is a frozen wasteland, peppered with valuable meteor strikes. Beneath, there is a vast network of tunnels occupied by convicts, their jailers and daredevil Noble scions competing to make their fortunes.

Morghull: Feral World. A heavily-forested world at the edge of the subsector. The natives consist of scattered bands of iron-age nomads who roam the endless forests, following herds of local herbivores. Known for their hardy physiques and physical prowess, Morghullites are dour, aggressive and brave, but also highly superstitious and mistrustful of outsiders.

Vannin: Death World. Made up of impenetrable jungle, it is part of the holdings of House Vilas-Lobo, albeit only in a technical sense: even to a house accustomed to the exploration of any world, no matter how hostile, there is little here to interest them. It presents no commercial use, nor is it interesting to scholars, and as such it is omitted from many maps of the House's holdings and they are responsible for no tithe from it.

Subsector Tenebris

Polarnus Station: Space Station. An orbital habitat-cum-shipyard, it is a giant asteroid hollowed into a multitude of labyrinthine tunnels. Once an ancient trade hub, it now acts as the headquarters for the front-line deployment of Crusade High Command, and is constantly bustling with the business of readying ships and soldiers for war.
