"Before he ever lifted his mighty hammer, there was the sword. Fantastic journeys beckon from the mysterious nine realms. Places of dark mists and fiery voids. Of winged creatures and giants in the ice. And the most alluring quest of all – the search for the legendary Lost Sword of Surtur. Hungry for adventure, Thor secretly embarks on the journey of a lifetime, joined by his loyal brother Loki, whose budding sorcery equips him with just enough magic to conjure up trouble, along with the Warriors Three – a band of boastful travelers reluctant to set sail on any adventure that might actually be dangerous. But what starts out as a harmless treasure hunt quickly turns deadly, and Thor must now prove himself worthy of the destiny he covets by saving Asgard itself."
