Bio-Purge of the Octarius System
From Warhammer 40k - Lexicanum
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 achieved this by using a modified version of the psychic doomsday device used to destroy the planet Duriel, which ensured no shred of biomass was left for Hive Fleet Leviathan to consume.[1]
This proved to be successful and a large part of the Hive Fleet was isolated and destroyed by interlacing Eldar attacks during the Octarius War. The Imperium, however, raged at the Craftworlds' slaughter and blindly attacked any Xenos spaceship within a dozen parsecs of its destroyed worlds.[1]
