The Vaxhallian Genocide was a notorious campaign conducted by the Forces of Chaos in 926.M41 upon the Imperial world of Vaxhallia. The vile Chaos warband known as The Purge sought to vent their hatred of all living things upon the unsuspecting verdant planet as their victim. The planet's surface was soon riddled with consumptive disease and crippling famine. Over the course of a single month, the Purge engineered the destruction of no fewer than 14 billion Imperial citizens.
