"The Fall of Asgard!"
While Thor is routing evil on Midgard, he misses treachery afoot in Asgard. Odin has commenced his time of rest and restoration, the Odin-Sleep, and Loki has gathered the enemies of the realm for an attack. Mountain Giants, Troll, Dwarves and Demons assault the gates. Karnilla the Norn Queen has released Balder and the Warriors Three, but they must dispatch Sif to gather Thor.
Loki is cunning if nothing else, and knows that all Asgardians must do the bidding of he who wears the Ring Imperial. Can they stop him from reaching the sleeping form of Odin?
