Position of Great Wolf
The position of the Great Wolf is the highest rank of the Space Marine chapter, The Space Wolves. The leader of the Space Wolves in the absence of their Primarch, the Great Wolf has final say on all decisions pertaining to the chapters actions in the 40K universe.
 Current Great Wolf
The current Great Wolf is Logan Grimnar. A ferocious but honourable man who leads the chapter with a strength and dignity unrivaled but by the Primarch himself. With fangs as long as a mans forearm and a grey mane to rival that of the chapters namesake, Logan commands the respect of all within the chapter, and also most outside. One of the most powerful individuals in the Emperor's domain, Grimnar's standing has made the Space Wolves a powerful chapter.
