But not the way you'd think… Meanwhile, Odin sent his brother Cul, God of Fear, into the depths of Svartalfheim on a vital mission. Will Cul redeem himself at last? And as a young god, Thor pined for a hammer beyond legend. Now his destiny arrives at last — for the War of the Realms will reach even here, centuries in the past!
