In this bonus episode included with the DVD box set, the Norse god Odin is held captive in the Land of the Dead after the trickster Loki aids the King of Hell. The Valkyries' efforts to free their ruler lead to further complications, forcing Odin to seal the river source of the World Tree and risk the realm's destruction. Loki counters by pursuing two protected keys, turning his attention to the invincible guardians Sigurd and Suvia, the latter a princess of Prishintia, while also holding the Valkyrie chief Freya to maintain control over the unfolding crisis.
