Astronavigational Information

Like much of the galactic void, the vast majority of the Prosperitas Sector consists of empty space and dull, lifeless rocks holding little interest to the Imperium. The sheer size of an Imperial Sector, however, means that despite this it is still home to countless billions flung across a myriad of planets, moons, asteroids, ships and space stations. These are spread out over an unimaginably large expanse, with particlar worlds or regions playing host to a dversity of different activities - sanctioned or not.

Traversing Imperial space is not a trivial task, requiring enormous amounts of time in realspace under conventional power, or the assistance of a Navigator to travel through the Warp - with all of the risks that that entails.

The Subsectors

The sector is divided into four subsectors: Primus, Secundus, Tertius and Tenebris.

Subsector Primus: home to the sector's capital, Duroverum, which acts as the seat of the Sector Governor, and has born the least of the brunt of Archenemy incursions into Imperial Space. [blah blah more info please]

Subsector Secundus: [blah blah]

Subsector Tertius: [blah blah blah]

Subsector Tenebris: formerly known as Subsector Quartus, the subsector was ravaged by an event known as the Lash of the Eye in 304.M41. [blah blah blah blah]

Regions of the Sector

Aside from the subsector divisions, there are specific areas of the sector that are notable for one reason or another.

The Rimward Marches: a vast region of the Prosperitas Sector not yet conquered by Imperial Forces. Beyond it lies the Lightless Gulf, where there are few stars for a considerable stretch of space. The region is a haven of scum and villainy: many remnant forces of the Regency retreated here, and it is the location of many untamed worlds including the suspected homeworld of the parasitic xenos known as the Thri'qun.

The Nemean Gulf: along the spinward edge of the Prosperitas Sector lies a vast region of unexplored space known as the Nemean Gulf. This region stretches for lightyears of uncharted void encompassing an area wide enough to contain several sectors, before eventually at the far side meeting the trailing edge of the Piscina Sector. Encompassing a vast number of worlds, from the Red Worldz of the Orks to the Graveyard at the Rimward edge where the Shavasti nomads are often found, the Gulf remains the most untouched region of the Sector.

The Tenebris Arm: part of a massive Warp rift and permanent Warp Storm nearly twenty thousand light years across known as the Eye of Terror, or Ocularis Terribus, the Prosperitas Sector orbits this storm impaled upon a reaching tendril, known as the Tenebris Arm, that spears into the eponymously named Subsector Tenebris and claims it with madness.

The Ættin Heima: a vast collection of worlds within the edge of the roiling warp-storm known as the Eye of Terror. Once a part of Subsector Tertius, they were conquered by tribes from the Eye. Given their immersion within the edge of the storm, dealing with this threat presents a serious challenge for the Imperium.

Trade Routes

The Trade Routes of the sector present vital lifelines for citizens and resources to track their way through the perils of the sector. Considered of the utmost importance, the Imperial Navy ensures that they remain open at all costs.

The Sol-Prosperitas Passage: the route blazed by Warmaster Durovera I when she first founded the Prosperitas Sector, the Sol-Prosperitas Passage remains vital for the sector's survival. The Warp tides are treacherous, but offer an unrivalled fast passage from the Prosperitas Sector through to the upper reaches of the trade-lanes into the Segmentum Solar and Sol itself.

The Cadian Corridor: forged by House Majid, the Cadian Corridor is a narrow passage of calm space that runs perilously close to the edge of the Eye and is heavily ravaged by pirates and raiders. Vital to the sector's economy, the corridor allows Prosperitas to feed the hungry fortresses of the Cadian Sector.

The Iron Stair: winding upwards from the galactic plane from the Forges of Castellum and Naximus Prime, the Iron Stair was once a rich trade route. With the Ork devastation of Persephon, the death of Caudica Secundus and Rebellion on Mawson's Wake, these have left the Rimward arm of this trade route quite poorly used, and many of the worlds along its path neglected.

The Prosperitas Trade Spine: named the 'Spine' for its vital role in supplying the majority of the major worlds of the Prosperitas Sector not already serviced by the Sol-Prosperitas Passage, the Trade Spine is currently under the control of House Di Firro who use it to support their House expeditions into the Rimward Marches.

Types of World

There is a large number of different kinds of world to be found within the sector.

For a detailed description of these, please go the Types of World page which explains them in more detail. Some of these are not currently found in Prosperitas.

Here is a brief rundown:

Agri-World: dedicated to crop and livestock production, primarily as a food source.

Armoury World: directly controlled by the Departmento Munitorum for the storage of armaments.

Cemetary World: given over to caring for the remains of the Imperial dead.

Civilised World: not dedicated to any specific purpose, though loyal to the Imperium.

Dead World: devoid of an ecosystem, atmosphere or native life.

Death World: inhospitable to human life due to its environment or biosphere.

Feral World: home to hunter gatherer, early agricultural or nomadic societies, under minimal influence from the Imperium.

Feudal World: home to pre-industrial societies, under little influence from the Imperium.

Forge World: directly controlled by the Adeptus Mechanicus for machine manufacture.

Fortress World: a bastion in the defence of the Imperium against outside threats.

Frontier World: at the fringes of the Imperium, and usually lacking an effective planetary government.

Garden World: dedicated to being a cultured retreat for the Imperial nobility (and others who can afford to pay).

Hive World: densely populated with hive cities, and home to the Imperium's workforce.

Industrial World: dedicated to heavy industry or resource extraction.

Knight World: home to Imperial Knights, and in the demesne of either the Imperium or the Adeptus Mechanicus.

Non-Compliant World: not necessarily actively hostile, but independent of the Imperium's influence.

Penal World: a prison planet, with a population primarily consisting of criminals.

Quarantined World: off-limits to contact with Imperial citizens.

Shrine World: dedicated to the Imperial Cult, frequently under the direct control of the Ecclesiarchy.

Space Marine Chapter Homeworld: directly controlled by a chapter of the Adeptus Astartes for use as a base.

War World: currently an active warzone.

There are also a variety of space stations, battlegroups and independent vessels throughout the sector that serve as permanent homes to millions of citizens - of varying levels of loyalty to the Imperium.

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. Rival to Ferraeus, it is the youngest of the Forge Worlds, having only been founded in mid-M.41. Although not as industrialised as other Forges, it is better known for the ancient pre-Imperial ruins found in its snow-capped mountain regions.

Duroverum: Hive World. Designated as the Capital of the Prosperitas Sector, it is the seat of Imperial Governance. Though rule of the sector is shared with the military leadership of the Office of the Warmaster – it is Duroverum where the Sector Governor reigns.

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: Hive World. One of the oldest planets in the sector, it was once a hub of trade. Now it is an idol of fallen splendour. The world’s atmosphere, polluted by industry, has forced its inhabitants into huge hive cities built around mountains.

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. No description yet.

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: Non-Compliant Shrine World. 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 against the fanatics of the now-excommunicated Cardinal-Emissarius Grulge who shelter there.

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

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 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 all approaching ships are turned away by the Gothic-class Righteous Indignation.

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. It has been earmarked for future military operations.

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.

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.

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.

Olethros Secunda: Partially Non-Compliant Civilised 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. Controversially, it still pays tithes to the Mechanicum of Naximus in recognition of this bond in lieu of Imperial taxation, and considers its duty to the Imperium to be in a distant second place.

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.

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.

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 it's capital and Noble Houses are reaching Imperial-levels of technology thanks to the world's mining efforts. Serf rebellions in 537.M41, under the guidance of a supposed Living Saint, have disrupted supplies.

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.

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

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.

Kelper Prime: Fortress World. A heavily fortified Fortress World on the Tenebris border, Kelper Prime controls one of the main Warp routes into Subsector Tertius.

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.

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.

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.
