The Infinite and the Divine written by Robert Rath
Before the being called the Emperor revealed Himself, before the rise of the aeldari, before the necrontyr traded their flesh for immortal metal, the world was born in violence.
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 artefacts – and people – of the galactic past. Orikan, a chronomancer without peer, draws zodiacs that predict and manipulate the future. But when an artefact 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?
