Helheim, Volume 2: Brides of Helheim — Cullen Bunn

Years have passed since Rikard's victory over Bera and Groa. In defeating the witches, Rikard saved his people. And yet he cannot rest -- he is still denied the promise of Valhalla. The warrior is condemned to wander the living world as an undead draugr. Now, new challenges lie before Rikard, as the draugr is sent to claim a Blood Debt from the mad warlock who taught the witches their dark arts.
