Changes

The '''Bio-Purge of the Octarius System''' began in late [[M41]], when the [[Craftworlds]] [[Biel-Tan]] and [[Iyanden]] united to incinerate dozens of [[Imperium]] and [[Ork]]-held worlds in and around the [[Octarius System]]. They achieve this, by using a modified version of the psychic doomsday device used to destroy the world [[Duriel]], which ensured no shred of biomass was left for [[Hive Fleet Leviathan]] to consume. This proves to be successful and a large part of the [[Hive Fleet]] is isolated and destroyed by interlacing [[Eldar]] attacks during the [[Octarius War]]. The Imperium however, rages at the Craftworlds' slaughter and blindly attacks any [[Xenos]] spaceship within a dozen parsecs of its destroyed worlds.{{Fn|1}}
