Ragnarok, Vol. 3, Simonson, Walter

In the end, the gods gathered together and met their foes on the Battle Plain of Vigrid. There, so the stories say, the gods and their Great Enemies slaughtered each other, the stars fell from the sky, Midgard itself sank into the all encompassing ocean, and the Nine Worlds were destroyed.

But not all the old stories are true. Thor survived as did most of the Enemies while the gods went down to defeat and the Nine Worlds became one vast land of desolation. Now, in his search for revenge, the last god standing hears the voice of one long dead and it sets him on a new course. The path he must tread will lead down into Helheim, the realm of Death, where he will encounter a host of threats--a mine of slaves charged with unearthing ore to forge god-killing swords, monstrous wolves who would tear him to shreds in their rage, and the numberless hosts of Helheim itself. For Thor seeks the hidden fate of Hel, Queen of the Dead, one of the architects of Ragnar k, and Lokis daughter And, behind everything, he will discover a secret that threatens the balance of all existence.
