Armageddon Subsector

The Armageddon Sub-sector is the Segmentum Solar administrative cube that holds the Armageddon System and the neighbour worlds that keep feeding its wars. It sits in the Armageddon Sector; hive-world Armageddon is the celebrity, but Jopall, Pyran, Monglor, Noctan, and a string of lesser rocks are why the sub-sector has a name of its own.

Every Armageddon war spills. Ork Roks, daemon fronts, and Imperial counter-crusades do not respect system borders, so the sub-sector is the real casualty list. Some of these worlds raise specialised Guard; others are just in the way. The chart still shows them because the hive world's gravity is political as well as physical.

The Armageddon Sub-sector still matters as the wider meat-grinder, not as a synonym for one planet. Unofficial fan maps keep the armageddon-sector parent and leave Armageddon itself a child of armageddon-system.
