Battle of Tralsak
Taking place on the Ice World of Tralsak, the battle saw the loyalist Legio Atarus and Legio Agravides clash with the traitor Legio Magna and Legio Victorum. In addition, loyalist Shattered Legions forces and the World Eaters fought across the disintegrating landscape of ice. Ultimately, the battle is indecisive and the ice planet of Tralsak is flash-boiled to steam. Each side uses the cover of the world-enveloping fog thrown up by the destruction to evacuate and redeploy them elsewhere. Nevertheless, numerous supporting Knights on both sides remain to fight.
