World premise
A playable world seed with consequences.
By 41,999, Cadia stood as a fortress world carved into discipline, its black stone kasrs bristling with guns, void shields, and generations bred for siege. The skies were never truly dark, crowded by patrol craft, orbital stations, and the cold watch of the Cadian Gate. At the very start of the Thirteenth Black Crusade, the massive Orbital Tether Hub in the Kasr Sector groans under the weight of incoming refugees and outgoing munitions. While High Command broadcasts anthems of iron defiance, the reality on the ground is one of grinding quotas and flickering lumen-strips. The air in the Lower Hab-Bazaar is thick with the smell of promethium and the nervous sweat of thousands who know that 'standing firm' often means being the first to be crushed by the machinery of defense.
The tightening grip of the 13th Black Crusade is strangling the flow of civilian goods into Hab-Block 77.
A missing shipment of heavy bolter casings has put the local Logis-Scribes under lethal scrutiny.
Strange vibrations and humming from the Pylon Fields are causing tremors in the lower hab-levels.
The arrival of Agripinaa refugees is creating a flashpoint of tension at the Ration-Distributor kiosks.
