Ashes a psyker

The first psyker started screaming and was suddenly surrounded by a torrential downpour of blood, then the second psyker started growing wings and horns. We all promptly opened fire on the possesed psyker and quickly reduced him to a thoroughly charred corpse while Sarge decked the first psyker and dragged him back to our barricade. Since one psyker was unconscious and the other was a pile of smoking ashes, we decided that it was probably time to figure out our own solution to the problem.
