Drakon Crusade
The Drakon Crusade was a vast Imperial Crusade that was launched, sometime after the Great Rift's creation, to reclaim the Drake's Nebula from the Word Bearers and Black Legion. Consisting of forces from the Astra Militarum, Battle Sisters, Titan Legions and the Ultramarines, led by Captain Galenus, the decade long Crusade ended with the Imperium victorious.[1]
