Fall of Marax
Warpsurge centuries on Marax brought heretical wars and daemonic incursions that crushed Imperial rule and left the death world to Chaos. Cities burned to ruins while pockets of survivors dropped into the tunnel systems. Isolation did the work a Chaos fleet might have taken years to finish. By the time Caligari Conclave reclaim missions charted the Balthar System again, Marax sat as a Chaos-held death world with no living hive government left above ground.
