The Space Wolves are a very old and wise race of beasts. They travel on the tails of comets, travelling far and wide providing guidance to all those who seek it. Elrok, the oldest and wisest of the Space Wolves. Is the only known "Space Wolve" to have visited earths actual landmass. It will be many years before the rest of the intergellatic tribe will be able to manifest themselves in physical form. As Space Wolves are the spirits of dying stars.
They do however have influence over many humans who carry out thier goodwill.

Obama "That was Elrok, he has asked me to represent the Space Wolves community on earth"
