Three deadly children, one mischievous god, and Asgard to save.
The time has come to face Hel. Despite their productive efforts to fill the goddess of Helheim's demands, Kara and her companions have come up short. Still, Odin demands they retrieve Balder at any cost. A peaceful solution is uncovered, if only the quick-to-wrath goddess will accept their offer.
The Midgard serpent is loose on the realms, leaving Thor and the Valkyries unsure where he will turn up next. He leaves destruction in his wake as he searches for Asgard.
On top of dealing with Jormungandr and Hel, Fenrir's tether thins, and the hound is ready to unleash his wrath on Odin. Angering all three siblings at once has been predicted to start Ragnarok.
