Thor, Vol. 1

The unthinkable has happened... Thor has fallen in fair combat, and Beta Ray Bill has won Mjolnir by right of combat. But neither warrior is contented with their victory. Thor is restless at having been defeated, and Bill is loath to take the hammer, even though he needs it's power to defend the refugees in his charge. But Odin is wise, and so wanders to the land of the Dwarves to comission an answer to this riddle.
