Ahriman: Hand of Dust (Black Library Advent Calendar 2013 #2)

On Prospero, a solitary living soul walks across the shattered world. Beneath the ruined spires, Ahriman, exiled son of Magnus the Red and destroyer of his Legion, contemplates what once was, what is, and what may yet be. And amidst the dust of the long-lost paradise world, the sorcerer faces his mistakes and decides his destiny.
