Orana

Orana was a hive world that, at an unspecified point in the 41st millennium, suffered a Chaos invasion transforming its capital hive into the Hellspire. Its coordinates were not recorded.

The Hellspire’s walls were composed of fused bone and flesh. Commander Dante led the Blood Angels within the Imperial force sent to retake the world.

Once the Daemon Lord had been banished, orbital bombardment destroyed the structure, bringing the Chaos hold on Orana to an end.
