When man was still young, before the monsters were born and when the Gods flourished, Odin, the God of wisdom, learned of the runes of Futhark. These mystical runes held a great magic power. It was only when Odin had acquired these runes that he learned of their true power. Eight of the runes had a power so heinous it could bring forth Ragnarok, the destruction of all worlds. Fearful that Loke, his treacherous blood brother would try to unleash this power, Odin decides to cast them far away.
He gives the runes to his trusted aid Ratatosk who is given the task of bringing them to Earth to hide them. But Ratatosk is attacked and killed en route, losing the magical runes. Four of the runes are lost around the world of Midgard, the other four fall into the realms of the Gods.
As a dark veil falls over both man and God, Loke discovers the location of the runes and the deadly power that they hold. He collects four fearsome, fallen champions to retrieve them, at any cost.
Odin, hearing of his kin's plan, chooses four of his own human warriors to stop Loke's dark harbingers and return the runes to him.
Hymer, a young Swedish Viking outcast by his village, Grim, a ruthless Viking on a mission to save his starving people, Tuva, a beautiful half Valkyria searching for her true past, and Thorgeir, an honourable Viking trained in the traditional way of the Vikings are the ones charged with this most dangerous duty.
Unaware of the future - the four heroes set out on their quest to defeat the evil Loke and halt the coming of Ragnarok - the destruction of all worlds.
