Any attempts at communication with the Cloven leads to aggression. Their motives are unclear, but they regard both humans and Chimera as enemies.
We caught the Cloven scavenging the bodies of our soldiers after a recent battle. It's unclear what they wanted them for. We know the Chimera devour their own wounded, but I can't imagine any man, even one of the Cloven, resorting to such savagery.
