Even when they inhabited bodies of flesh, Trazyn the Infinite and Orikan the Diviner were polar opposites. Trazyn, a collector of historical oddities, presides over a gallery full of the most dangerous artifacts - and people - of the galactic past. Orikan, a chronomancer without peer, draws zodiacs that predict and manipulate the future. But when an artifact emerges that may hold the key to the necrons' next evolution, these two obsessives enter a multi-millennia game of cat and mouse that ends civilisations, reshapes timelines, and changes both forever. As riddles unwind and ancient secrets are revealed, the question remains. Will their feud save the necron race, or destroy it?
