Brides of Helheim #1 (Oni Press, 2014)

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, a new challenge lies before Rikard: to face the demon beast Mórðvíg in a brutal conflict.
