Garmr Hrodvitnir

''"My what big teet you have. The better eat the world." -Garmr Gorewolf''

Also know as the Gorewolf. One of the mightiest champions of the Blood God Khorne to walk the earth, and one of the few characters in the series to have matched Slayer Gotrek in battle. Garmr is a Chaos Lord from Norsca who has carved a mighty path of destruction from the heart of the far north, paved with the skulls of his enemies to reach the Slayer Keep of the World's Edge Mountains, where his road of skulls is to end. Garmr intended to raze the Slayer Keep to the ground, claim the skull of Doom-Seeker (whom he knew as the One Eyed Dwarf) and thus open a gateway to the realm of Chaos which would thus consume the entire Old World and turn it into an endless daemonic battlefield which would allow him to fully indulge his bloodlust.
