"Cartwright's reports said the Cloven might be working with the Chimera. There's no proof of that. I've never seen any Cloven markings in all of the Chimera facilities I've destroyed-- and I've destroyed more than a few. Until now, that is. This is the first time I've seen any Cloven markings inside a Chimera conversion center... if that's what this is. Why here? Probably the poor bastard fell down the elevator shaft and scrawled this symbol before he died? No bones though. Maybe the Chimera Drones clean up organic material as part of their programmed routines?"
