With his friends and family on the line, Clayson must find a way to heal the world.

Rimduum is shattered. Stranded on the surface, my friends and I search for survivors of the mithrium crown's terrible power. Desperately, we track down refugees as we build a network of safe houses to shelter the vulnerable from roaming bands of darksmiths. But the more we help, the more our power shrinks.

Until new clues force me to strike a strange alliance. My search for a power strong enough to fight back will lead us all into dangerous territory. To the forest of Gamgim, filled with wraiths. To a city of fallout where the living buildings want nothing more than to absorb you into the machine. And to the dungeon of the champion Erikzin Brightstorm.

Though darksmiths lie around every corner, the fate of the mithrium poses an even greater danger. Uncovering its origin could lead us to a power that would make the world right again. But the truth has already cost us so much, and I'm afraid of where it might lead. Will the power add up to something I can use to protect those I love? Or will the secrets I reveal increase the deadly cost born by all who find themselves prisoners in the world of Rimduum?
