It took place more than a thousand years ago...the Twilight of the Gods and the destruction of Asgard, home of Thor and Odin. But a sculptor named Vidar still remembers that horrific time. He is an immortal, a bastard son of Odin, and one of the few Aesir to survive the Twilight. Weary of the war-living ways of his kind, he has forsaken Asgard for Earth, traveling from land to land and guarding the horn of death that once protected the gates of his home. Now, after centuries in this world, Vidar hears the anguished cry of a kinsman. Asgard has been rebuilt, but a terrifying new enemy wearing Odin's war-mask has stolen Thor's hammer - and is planning a holocaust to consume not only the gods' home but Earth as well. Vidar knows he has no choice but to return to Asgard - and take the horn of Hell with him.
