Black Crusade of Sicklefell
The Black Crusade of Sicklefell was launched in M36 and targeted the Imperium's Hive Worlds surrounding the Kreel Nebula. It lasted a century before finally being stopped by the Imperium, but during that time the Forge World Barnassus was destroyed and the populations of thirty three worlds were systematically murdered by the Crusades' forces.[1]
