"I murdered thousands for the Emperor and he gave me nothing except his damning silence. Now his lapdogs yap for every life I take, while the gods promise me the galaxy."
- — Svane Vulfbad
Svane Vulfbad was a Renegade Wolf Lord of the Space Wolves Space Marine Chapter and leader of the warband of Heretic Astartes known as the Blood Wolves. He became so disillusioned with the grinding workings and soul-killing bureaucracy of the Imperium that he turned to the worship of Chaos, and more particularly the faith of the Blood God Khorne.
Wolf Lord Harald Deathwolf and his Great Company were charged in 913.M41 by the Great Wolf Logan Grimnar to track down and execute the notorious Traitor. Deathwolf and his company eventually uncovered Vulfbad in the Cliedes System, tracking their elusive quarry to the storm-wracked moon of Gallimius. Deathwolf rode his ferocious Thunderwolf through the planet's ferrite dust storms at the head of a small strike force of Wolf Scouts. The visibility was so bad that Deathwolf had to track his quarry purely by scent, but he later claimed the stink of rank sweat and treachery was so strong it was child's play to follow. It has been said that Harald's senses are so sharp he can smell the fear of his prey from several leagues distance.
After weeks of stalking their prey, Deathwolf's hunting party cornered Vulfbad atop a dust-crowned mountain just as the vile Traitor was completing a sorcerous summoning ritual that would have seen his traitorous forces thronged with daemons. The Renegade Space Wolf fought like a madman even after his allies had been slain, badly wounding Harald's Thunderwolf in the process, but he was ultimately outmatched. As Harald brought his axe around to deliver the deathblow, a bolt of lightning struck them both. When the dust settled all that remained of Vulfbad was his Frost Axe, a shard of which now juts from the cybernetic jaw of Harald's Thunderwolf. The beast has been known as Icetooth ever since.
