Story time! Thor, along with Þjálfi and Loki, went on a journey to the land of giants. The king of the giants gave them challenges, several of them for Thor, which they failed. Thor isn't used to defeat. What can he do?
The end of the tale shows how everything in the story is an analogy, and the effects of the challenges are the reasons the story was told in the first place. -via Geeks Are Sexy
