|Affiliation:||Chaos (Nurgle), former Imperium|
During its invasion by the forces of Nurgle, the Black Templars' Lastrati Crusade, led by Marshal Armante, came to aid the Imperium's forces defending Arthas. Due to their efforts Arthas remained free from Nurgle's grasp for sometime, but they suffered heavy causalities as a result, while fighting the Death Guard and Daemons, and they soon found themselves the only resisting force remaining on the planet. They fought on alone until Armante was killed in the battle and with his death, all hope of saving Arthas was lost; though the remaining Black Templars refused to escape the planet, without the Marshal's body.
With their time running out, the remaining Black Templars were led into battle by the Emperor's Champion Horst and the Chaplain Ferdinand, as they ferociously fought the Death Guard and Daemons that stood in their way of reaching the area where Armante had fallen. Unfortunately for the Crusade, the forces against them were personally led by Malke Vos and The Fly Lord who destroyed the Black Templars, and with their defeat claimed Arthas in Nurgle's name.
