The ritual at the beginning was to Fenrir. Fenrir is the great wolf in Norse Mythology. I don't think the writer intended this to be Logan the Wolverine (Canadian). This is Logan the Wolf (Norse). Someone in the same species of bone claw mutants. Also, there are no wolverines in Europe. With the one eye, Magneto is similar in appearance to Odin. One more thing, the director said the claws are bone. He thought the bone claws in the official movies looked too much like sticks, so he shaped them for this short film.
In fairness the claws are more like as they would be represented in animals, more like a finger nail from in between each finger than bone, and those bone "claws" in the movie looked like damned Unicorn horns and not "Claws".
