Changes

In his service to the Crusade, Dematris was part of [[Lieutenant (Space Marine)|Lieutenant]] [[Cassian]]'s Ultramarines strike force, which destroyed the [[Chaos Cults|flesh-cults]] that had overthrown the [[Imperium]]'s rule on [[Knossa]]. Afterwards, they left the world to rejoin the main forces of the Indomitus Crusade, but disaster struck when their [[Strike Cruiser]] ''[[Primarch's Sword]] '' was hit by a [[Warpstorm]]. Though the Strike Cruiser eventually escaped from the storm, it was left heavily damaged and the Ultramarines found themselves stranded in the [[Kalides System]]. With the Primarch's Sword unable to enter the [[Warp]], Cassian consulted with Dematris and [[Librarian]] [[Keritraeus]] on their best course of action. After much consideration, it was decided they would go to the nearby Imperium world [[Kalides Prime]], so they could repair the ''Primarch's Sword '' and rejoin the Indomitus Crusade. Cassian also agreed with Dematris, that they might face a world in the grips of [[heresy]] and the Lieutenant ordered his forces to prepare for battle, as they began to travel to Kalides Prime.{{Fn|1}}
