Thor, Prince of Asgard, survived a great battle with the Jotun giants, but his army and his wife, Sif, lay slain around him. Now from Svartalfheim, the realm of the dwarves, come new foes. If he survives, he must journey to Avalon, where the Garden of Eden and the Yggdrassil lay. It is there that he may find his father's eye. Alas, the road is filled with perils.
