(Seeing Red) Mertroy the Mindless

Lore
Mertroy's brainwashing left her consciousness in a perpetual fog. The only clear notions she can discern are to fight and kill, and she clings to them obsessively. Naturally, one whose words has been reduced to mad screams is unable to know whose blood she spills, even if it is her brethren's.
