In the frozen Utmark of Midgard, young Arnulf Haraldson finally earns his oath ring and steps beyond the safety of Brossfell's Great Hall alongside his closest friend and rival, Eirik. What begins as a journey into the wilds soon becomes something far darker when the boys uncover ancient horrors stirring beneath the northern mountains and within the ruins of Blacksteel Castle.
As whispers of the dead spread across the land and a shadow falls over the north, Arnulf finds himself drawn into a struggle far greater than war between clans. Old gods watch from beyond the veil, forgotten evils awaken, and something ancient hungers beneath the moonlit skies of Midgard.
Bound by oath, grief, and brotherhood, Arnulf and Eirik must face the darkness creeping into their world before it consumes not only their home-but themselves.
