The Wolves of Brandenburg
Warcry is a Carrier Pigeon spirit. He first appeared to Erwin before his First Change although he didn’t know it at the time. It is a nature spirit, but has the touch of the Weaver. Warcry specifically embodies those homing pigeons used to deliver messages about war, and thus a spirit of Rage. Warcry will only teach gifts to homid Garou engaged in battle with his fellow man.
Warcry taught Erwin how to speak with Beasts.
