Starting a Celestial Lions army!!
Khabor Trexus, the newly promoted 1st War Leader of the Celestial Lions, is one of the few remaining Firstborn Astartes that managed to evade the wrath of the Inquisition. He is equipped in Indomitus Terminator Armour and wields the 'Spear of Khattar' and the Storm Shield 'Kaisereine', bringing the Emperor's vengance and defiance wherever they are aimed. He returns with his recently restored Chapter to Armageddon's 4th war. His hatred for the Orks is matched only by those of his brother Chapter of the Black Templars. He has vowed to cut down anyone who gets in his way of restoring his Chapter's honour and avenging those battle brothers who were wrongly slain by the Inquisition.
Yup, starting a new army. As the Celestial Lions are a successor of the Imperial Fists, I'm gonna run this guy as a Lysander Stand-in
