This section of the Warhammer 40,000 Battles Book details the Mardannon subsector, the chief stronghold of the Imperium in our portion of space. This treatise includes Ordavis, in the Carpithica system. These entries change from time to time as battles are fought and won, and the fortunes of these distant stars wax and wane. After The Battle for Ordavis, I'll post an update for the Carpithica system when I update the Battles Book. Until then, familiarize yourself with the 'core' planets of the Mardannon Sector! Included is a small Warp Chart for planning those pesky jaunts through the Immaterium!

Mardannon is one of the most advanced and civilized of the subsectors listed here, due to the relative safety of the zone. It is far away from most of the alien dangers in the sector such as the Orks of Magnum Sierra, but is not entirely untouched. Daemonic cults seem to flourish in the population, and the Inquisition is known and feared throughout the subsector.
Mardannon System
- Mardannon Prime
- History: Colonized in the early part of the Old Crusade, Mardannon has become a massive hive world sporting no less than eight massive hive spires. The orbital docks and shipyards surrounding the planet are top notch, as Mardannon serves as Battlefleet Command for the entire sector.
- Geography: The surface of Mardannon Prime is covered in snowy mountains and low plains. The hives belch smog continuously into the atmosphere, and after five thousand years the sky is perpetually grey. Although there aren’t any major ash deserts the southern wastes are particularly hot and deadly.
- Inhabitants: The people of Mardannon Prime are a generally happy lot, generally free of corruption and are an industrious and productive people. Service in the regiments of the Imperial Guard is voluntary, and there are always thousands of hivers seeking another way of life in this manner.
- Mardannon Secundus
- History: Terraformed shortly after the colonization of Prime, Mardannon Secundus is a thriving Agri-world. Secundus produces food bound for several systems within the subsector, and is guarded like a treasure. The planet sits not far from Prime itself, with the Fleet close by.
- Geography: Most of Secundus is flat plain littered with Agri-Domes and the Habitats of the Serfs. In the north, massive mountains dominate hemisphere. Most of the southern hemisphere is under high density water.
- Inhabitants: On Secundus, the farmer’s way is the only way. The Agri-Barons rule in a feudal manner, with the top Agri-Barons trading with off-world merchants for the highest profits. For the serfs themselves, life is made easier with abundance of technology, but only slightly.
- Ortaph Maximus
- History: As soon as Mardannon Prime was slated for colonization, Adeptus Mechanicus Explorators arrived on this small and nearly barren planetoid and began the construction of what would become one of the most important Forge Worlds in the entire sector. Today, Ortaph Maximus is covered nearly entirely by Mechanicus compounds and orbital shipyards.
- Geography: Ortaph Maximus is inhospitable and barren, with a broken and jagged granite-like surface. Abundance of many minerals within the crust of the planet is cited as the reason for Explorator colonization. Human life cannot exist outside the Forge Hives due to the weak and polluted atmosphere.
- Inhabitants: Nearly all the inhabitants of Ortaph Maximus are adepts of the Machine God. The most important items churned out by the Forge Spires of Ortaph Maximus are myriad pieces intended for the construction and repair of capital ships. Naval munitions are also fabricated here.
Bulgaris System
- Bulgaris
- History: Discovered not far from Mardannon, this gas giant was quickly recognized as an abundant source for Pyrrin, a gas that when condensed becomes a highly flammable liquid. Prized as a source of fuel for the sector’s battlefleets, Bulgaris is well monitored and defended.
- Geography: Bulgaris is a binary star system, and the radiation of the twin suns is fatal to humans. However, it is exactly this radiation that produces the environment needed to create the Pyrrin gas. The planet itself is entirely composed of various stellar gases and liquids towards the surface. It does not have a breathable atmosphere and the gas miners avoid entering it.
- Inhabitants: Bulgaris has many orbital stations in geosynchronous counter-orbit, keeping them in the shadow of Bulgaris at all times. The inhabitants of these stations are Adeptus Mechanicus and various guildhouse workers from the nearby systems of Carpithica and Mardannon.
Garrinax Seclusia System
- Garrinax Seclusia
- History: Colonized during the initial expansion into the sector, Garrinax Seclusia became the repository for malcontents during the Crusade. As the oldest penal colony in the sector, Garrinax Seclusia has quite a reputation throughout the Guard and Navy, as well as hive criminals who have a notion that the place exists.
- Inhabitants: Only home to inmates and their tenders, Garrinax is almost totally devoid of human settlement. There are more living people scattered throughout the systems’ asteroid belts, of which it has three. The asteroids are rich with plenty of minerals used in a multitude of industrial processes, including metals and gases. The Adeptus Arbites train members as prison guards here before they are moved to active duty on worlds throughout the sector.
- Geography: Garrinax Seclusia has a rocky surface with barely any water or vegetation, and where such occurs is limited to zones around the equator. The equator of the world is wracked with seismic activity and is generally considered uninhabitable. The planet also teems with various mineral deposits that, while valuable, are extremely dangerous to harvest. Nonetheless, inmates are still assigned to harvester teams to mine resources from the planet as a means of punishment and / or execution.
Kathis Mundanus System
- Partisan Imperious
- History: One of the oldest hive worlds in Mardannon, the hive cities here are over five thousand years old. The relative high tech of the entire Kathis Mundanus system is maintained by Guilders closely working with adepts of the Machine God. Since the 13th Black Crusade, this world has been embroiled in terrible wars of faith with guerilla insurrectionists.
- Inhabitants: There are eight huge hive cities on Partisan Imperious, and the factorums churn out materials that are needed all across the sector. Lucrative trade agreements with the Imperium have made the aristocracy rich. The majority of the populace still lives in the depths of the hive cities, but enjoy higher tech and comfort than similar Imperial worlds.
- Geography: Partisan is not badly polluted, but most of the surface is covered in high density water, unsuitable for drinking unless processed. The hives are built half in the water and half out, as only about twenty percent of the planet is dotted with islands of habitable land.
- Mordredus
- History: Colonized a thousand years after Partisan Imperious, this world was once home to marauding ork pirates. After being granted this cleansed world, the remnants of the Catachan 146th worked closely with the Adeptus Mechanicus to erect the hives. Like nearby Partisan Imperious, the people of Mordredus have had to contend with guerilla insurrectionists in all of the hives and at large elsewhere on the planet.
- Inhabitants: Descended from the Catachan 146th, the populace of Mordredus lives within three huge hive cities. As a production facility of assorted wares, these cities always deliver a surplus of goods that is sold off to Guild traders from Partisan. The hivers live well enough, as the hives are for the most part open and the atmosphere non-toxic.
- Geography: Mordredus, in stark contrast to Partisan Imperious in the same system, is largely covered in rolling mountain ranges. About forty five percent of the surface is covered in greenish water that when condensed and purified is highly nutritious. Static storms of varying magnitudes careen across the surface during storm season, but for the most part the world is idyllic.
Drogo System
- Drogo
- History: Drogo has been a primary source of income for the sector’s trading guilds for as long as it has been a recognized system under Imperial compliance. For about five thousand years, the crystalline surface of Drogo has been mined for Drogite, a very special mineral that can be rendered a hundred different ways for a hundred different reasons – at least so say the Mechanicus.
- Inhabitants: Inhabited by the Guilders and Mechanicus rendering installations, Drogo is a very heavily populated system – just not on the world itself. The space stations orbiting Drogo are in geosynchronous orbit with the corresponding mining station on the surface, and giant ‘crystal crawler’ machines till the soil in a systematic harvesting of the Drogite encasements that are literally spilling out of the surface, even after five thousand years. On the surface, ignorant techno-barbarians avoid the installations and mining crawlers and eke out an existence near the salt oceans, where the Drogite crystal does not form as readily.
- Geography: Drogo is covered in a thick, mineral laden soil which when exposed to oxygen and sunlight can actually begin to grow a crystalline residue when cultivated in certain conditions. The entirety of the planet has been converted by the Guilders and Mechanicus to actually promote this nutrient crystallization transfer. Much of Drogo is covered in differing kinds of water, and near the alkaline seas of the northern hemisphere is where the Imperials make their presence. The techno-barbarians regard the entire region as haunted by metal snakes that churn the earth – the crystal crawlers.
- Araba
- History: An explorator world, Araba is home to some of the most sophisticated equipment in the sector. Several Mechanicus Skitarii regiments are stationed here, as is the majority of the Mechanicus fleet presence in the sector.
- Inhabitants: The Explorator Corp of the Adeptus Mechanicus is the sole body responsible for events and equipment on Araba. The installations here are used to instruct new Mechanicus Adepts and refit stations all over the sector. As a result, there is a very machine-like and cold society on this world.
- Geography: A vast desert world made up of varying topographic terramorphs, Araba is generally considered quite a hostile environment. In the massive Mechanicus dome cities, life is lit by primitive haloglobes in dark corridors. Mountains of vast proportion jut from the earth in windswept upturns, their jagged spires piercing the very sky.
Carpithica System
- Carpithica
- History: For nearly four thousand years, Carpithica shone as a pristine example of the realization of the Imperial ideal. It was colonized shortly after the rediscovery of Ordavis, another planet in the system. It is a civilized world not overpopulated (due to heavy tithes of personnel to the Imperial Guard and other Imperial agencies) or heavily polluted. Vast tracts of land were set aside for farming, and the planet was a prime source of agro products for several systems. Until the Orks arrived.
- Inhabitants: Carpithica has been a war zone for nearly 8 years, where the human population has been pitted against a horde of Orks of various tribes united under the Waaagh!! of an as yet unknown warlord. Due to the large area of agro land between the population centers, the ork invaders and the human farm workers have been fighting a running battle in the fertile no-man’s land. At present, the orks control a large area near the equator, but are pressing northward into the human controlled area of the planet.
- Geography: Most of Carpithica is covered in salt oceans, but there are several large continents dotting the globe. Two of these continents are used by humans for the fertile agro land in the northern hemisphere, and a third continent in the southern hemisphere is the industrial zone. Heavy jungle and mountains ring the equator, where the ork base camps are. Ice continents have formed around the north and south poles, all in all Carpithica is one of the nicest worlds in the sector, environmentally speaking.
- Ordavis
- History: A massive hive world, Ordavis was brought into compliance with the Imperium once again during the Old Crusade. The people had lost contact with the Imperium for nearly a thousand years following a massive warp storm in the area, but continued to maintain throwback traditions that identified its folk as belonging to the Imperium.
- Inhabitants: Stern hive workers form the body of the population, while a few Guilder and Imperial noble houses handle trade and other off-world business. Orks arrived in the system 8 years ago, during which time reinforcements from the Imperium have arrived piecemeal, not enough to break the grip the ork flotilla has secured on the sector.
- Geography: A small planet with a grey skyline, a good portion of Ordavis is actually rocky crust of the planet, resembling at times a rock quarry. Many of the hives are built down into the crust, while others are built as spaceports and stretch into the stratosphere. There isn’t much drinkable water, and several hives are actually giant mega-condensers that struggle to support the atmosphere of the planet, which is only just barely livable by human standards.
