Centuries ago, the murder of a beloved king tore apart the Kingdom of Caledun. The land was plunged into chaos and thousands perished. A new order was established in an attempt to return Caledun to its former glory. It failed, but in its place rose the beginnings of the Code. During this same period, the mystical caretakers of the Great Wood retreated from the world of Kal Maran, their disappearance an ominous harbinger of the suffering that was to follow. The Great Wood now grows out of control. Cities, towns, and villages have fallen before the relentless march of the forest.

Norse chiefs meet Christian kings on Midgard's battlefields, as Loki's army of the dead clashes with Odin's golden shields on Asgard. An ancient premonition of death hangs over all.
