Fenris

Fenris is the death world of the Space Wolves, a planet of ice, volcanoes, and a world-ocean that swallows islands with each season. The Fang stands on the polar continent of Asaheim, and the tribes below supply the Chapter's recruits. Leman Russ was raised here, and the world has since endured the Battle of the Fang, the Siege of the Fenris System, and more than one visit by Magnus. Russ departed from the Fang on his last Great Hunt; Bjorn, Logan Grimnar, and Ragnar Blackmane still hold the Fenris System against Magnus’s Thousand Sons across the same ice theatres.
