Hercules wanted to save the Norse god Balder, but Balder explained that his death was foretold in the Book of Fates and could not be changed. Sure enough, Hercules was tricked by Loki, the god of mischief, into accidently killing Balder. An enraged Thor tried to kill Hercules with his huge stone hammer, but Hercules beat Thor and took him to Valhalla. There, Odin -- the king of the Norse gods -- explained that two parts of an ancient prophesy had been fulfilled. If the third part took place, the final nightfall and end of all things would occur.

Odin believed the answer to the riddle ""When light dies, then will Ragnarok begin"" would bring about the end of all things. Loki went to Odin in disguise and gave him a metal mask. When the king of Norse gods looked into the mask, he was blinded -- which fulfilled the third tragedy. Loki then blew Gilma's Horn, which brought on Ragnarok, and he killed Thor witha poisoned dart. When Hercules poured paint into the Book of Fate, he returned to the moment before he accidently killed Balder. He exposed Loki's plan to Balder and thor, saving their lives.
