Thrakos System

The Thrakos system resides perilously close to the recently opened Great Rift and was a major system of Imperial control before the events of the 13th Black Crusade with Forge World originating from the Dark Age of technology and multiple large population centers.

Before the era of Imperium Nihilus, the Thrakos system had seen it's fair share of consistent external attacks due to the strategic and logistical importance, the most recent one being a Genestealer Cult uprising which still has a large underground movement after decades of purges. It's also received and resupplied a number of crusade fleets and astartes chapters operating far from their regions of origin, with a special relationship formed with the domain of Macragg due in part to Guilliman's conquest of the system during the era of the Great Crusade. In the time following the Horus Heresy saw great growth come to the system, with the Forgeworld of Thrakos V and the population of Thrakos IV being integral in the Imperial war machine which stretched across the sector.

After the Great Rift opened cutting off Imperium Nihilus from the rest of Imperial control, the Thrakos system was well defended from the initial attacks yet isolated from all but the closest neighboring systems, all of which now began broadcasting an overwhelming number of distress calls. Ultimately the besieged imperial systems nearby drained the majority of naval and imperial guard units originally stationed in Thrakos in a fruitless effort to establish some sort of connected imperial domain. The large majority of expeditions were simply lost in the warp and even fewer returned.

With the system now comparatively lightly defended, many external forces find a time ripe for action. Worse yet, the lack of a singular enforceable Imperial command opens the door for internal forces to contend among themselves and leave the tithes of soldiers and war machines which replenished the defenses unpaid. While still declaring themselves for the Imperium, each military faction, hive city, and forge fane found themselves at odds against each other for the same resources and forced to make some shaky alliances. Meanwhile the forces both heretic and xenos strike from the shadows, igniting dozens of direct or shadow wars against the shattered Imperial remnants or themselves.

It is into this disunity which the world of Thrakos VIII - previously condemned to destruction by exterminatus for it's corruption - finds itself re-birthed into from the maw of the Great Warp which swallowed the planet's shattered husk when it yawned across from the sky. Like a baleful eye staring out from the great warp, the shadow of the Thrakos VIII now casts itself in the skies of the system. Foul sorcery emanates from the cracked surface of the daemon world of which the corrupting influence can be felt by any mortal trying to sleep while the bale eye hangs above them.

Planets

- Thrakos I - Dead World - Barren due to proximity to the star and constantly washed with radioactive solar energy. An ancient station keeps itself in the shadow of the planet as it moves about it's yearly rotation, a relic remaining from the Dark Age of Technology. There's a small AdMech presence on the station but the inhospitable environment (even indirectly in the shadow of the planet) keeps it a small garrison.

- Thrakos II - Death World - Atmospheric conditions make it toxic for anyone outside of an environment suit due to the constant volcanic activity which the planet sees. Mining outposts exist in the most geological stable of locations with access to an constant stream of raw materials naturally tilled up from the mantle.

- Thrakos III - Agri/Shrine World

- Thrakos IV - Primary Hive

- Thrakos V - Forge World

- Thrakos VI - Gas Giant

- Thrakos VII - Gas Giant

- Thrakos VIII - Daemon World
