"...Comes a Dark Stranger!"
While traveling Asgard, along with his half-brother Loki and the Warriors Three, a young Thor is challenged by a dark stranger.
Thor and Loki follow this mysterious Dark Man back to his realm, where they narrowly escape from a beautiful temptress. When Thor finally reaches the Dark Man's fortress, he finds a large room filled with fallen warriors, all turned to stone.
He then battles the mysterious Dark Man and his temptress wife. Badly beaten, and near death, Thor refuses to give up. This simply angers the Dark Man, who vows that they will meet again, and with that returns Thor to Asgard.
In Asgard, Loki, who had fled when they were confronted in the Dark Man's lands is telling Odin of Thor's demise. Loki is surprised to see him alive and well. It is then that Odin tells Thor that the beings he faced where two great destroyers of warriors, Fear and Desire.
