You are the warrior, Lone Wolf, last of the Kai Masters of Sommerlund and sole survivor of the massacre that destroyed your kinsmen during a bitter war with your age-old enemies the Darklords of Helgedad. You have given your solemn pledge to restore the Kai to their former glory, ensuring the security of your land in the years to come. Diligent study of the tome called The Book of the Magnakai has enabled you to master only three of the ten Magnakai Disciplines. Now, you must fulfil your pledge by completing the quest first undertaken by Sun Eagle over one thousand years ago. It is a quest that will take you deep into Castle Death - a dangerous journey not completed successfully since the time of the Sun Eagle.

Victor and Eli started out as college roommates brilliant, arrogant, lonely boys who recognized the same ambition in each other. A shared interest in adrenaline, near-death experiences, and seemingly supernatural events reveals an intriguing possibility: that under the right conditions, someone could develop extraordinary abilities. But when their thesis moves from the academic to the experimental, things go horribly wrong.

Ten years later, Victor breaks out of prison, determined to catch up to his old friend (now foe), aided by a young girl with a stunning ability. Meanwhile, Eli is on a mission to eradicate every other super-powered person that he can find aside from his sidekick, an enigmatic woman with an unbreakable will. Armed with terrible power on both sides, driven by the memory of betrayal and loss, the arch-nemeses have set a course for revenge but who will be left alive at the end?
