Creed is a Captain of the Keepers of the Fallen
Each captain maintains a branch of the pack, Creed delegates the scouts.
Creed was the first wolf that Hemlock recruited into the Keepers. He was cast out from his pack for courting the Alpha's decided breeding female, and thrown out into the wilds. He befriended Hemlock, and is canonically her best friend. They often explore together, and on days with good weather, the Commander herself accompanies him out on his missions into new lands.
He is also the breeding male of the Keepers of the Fallen!
