Scouring of Nosgoth

The Scouring of Nosgoth was an Imperial castigation campaign conducted by the bellicose and unforgiving Sable Lions Space Marine Chapter against the hive world of Nosgoth that had fallen into bloody insurrection due to the rise of hidden Chaos Cults.

History
A Chaos Cult uprising upon the strategically important Hive World of Nosgoth engulfs the planet, until elements of the Sable Lions Chapter arrive unbidden, to reclaim the besieged world for the Imperium. In a series of well coordinated surgical strikes and scorched earth assaults, the Sable Lions decimate the cult's ranks, freeing Nosgoth from the insidious threat of the Ruinous Powers.
