Armante was a Black Templars Marshal who led the Chapter's Lastrati Crusade and came to the defense of the Imperium world of Arthas when it was invaded by the forces of Nurgle. Due to the Crusade's efforts, the forces of the Death Guard Chaos Lord Malek Vos and the Nurgle Daemon Prince The Fly Lord were kept at bay, though the Black Templars suffered heavy causalities as a result. As the battle wore on, the Crusade soon found itself fighting alone and was stricken a fatal blow, when the Marshall himself was killed. With his death, all hope of saving Arthas was gone, though the remaining Black Templars refused to escape until they could reclaim Armante's body. Led by the Emperor's Champion Horst and the Chaplain Ferdinand, the Crusade fought ferociously to reach the Marshall's body, but were destroyed by the Chaos forces that stood in their way, who were personally commanded by Malke Vos and The Fly Lord.
