Lorhan Hive Massacre

The Lorhan Hive Massacre, known unofficially as The Fire Pit, was an Imperial castigation campaign conducted by the Ashen Disciples Space Marine Chapter against a Chaos-infested hive city on the world of Yrat II.

Background
The Fire Pit is the name given to the Imperial Campaign, officially known as the Lorhan Hive Massacre, was an Imperial Campaign against the Chaos-tainted hive city of Lorhan on the planet Yrat II. The original stages of the campaign consisted of the chapter sending squads of Space Marines down into the hive to destroy any chaos corruption while Ecclesiarchal representatives within the hive preached to the upper hive.

Once it was revealed that the Hive's Governor, Borad Klannis, was the leader of a large heretical cult in the upper hive, the chapter personally killed every noble within the Hive under the fear that they may be part of the cult, until they left and orbitally bombarded the hive until it was completely levelled. In order to make sure no taint was still there, the chapter flooded the underhive with mass amounts of promethium and then setting it alight. Only when the fire stopped did the chapter leave, deeming the hive cleansed.
