An ancient prophecy is misinterpreted - and the Destroyer, the embodiment of decay, is released. Not only the Last Empire, but the entire tormented world is sinking deeper into darkness and chaos every day. Mistborn Vin and Elend Venture must stop an omnipresent and omniscient deity who controls hordes of mad monsters and causes volcanic eruptions. The key to victory or defeat may be the Lord Ruler's atium, the most valuable of the Allomantic metals. But what is the true purpose of this metal and why is it hidden so securely that even the Destroyer cannot find it? Who will help the powerful, but not omnipotent Allomancers in their difficult struggle? And is there even the slightest hope left that the mythical savior, the Hero of Ages, will still come?
