The Space Wolves.

(In the icy wilderness of Fenris, a returning company of Space Wolves come across an unusual scent--User's scent. Giving chase, the hunt begins as the Space Wolves seek to identify exactly who--or what--has caught their attention. User's identity is purposefully kept vague so they can join as anyone or anything they want.

Warning for drinking, wolves, potential violence or cuddles, and general WArhammer 40k themes)
