Book 5

Undying

by John French

Published 8 May 2025
The greatest sorcerer of the Thousand Sons has finally found the relic he's been searching for – the Key of Infinity. But is it too late for him to use it?

Ahriman languishes on the threshold of space and time, adrift in a sub-realm of unknowable dimension and aspect. He has found it at long last: the ancient device known to the necrons as the Key of Infinity. This should be his moment of triumph – but he is not the Ahriman he used to be. Betrayed and lost, he is a solitary sorcerer, bereft of allies, standing amongst the smashed and ruined ephemera of his grand designs. With his dreams as dust and his Legion consumed by the fires of the Pyrodomon, Ahriman must fight his way across the shattered remnants of his past if he is to have any hope of saving his future.

The Omnibus

Published 4 May 2017
The name Ahriman has lived in infamy ever since the galactic war of the Horus Heresy. The greatest sorcerer of the Thousand Sons, and protege to the primarch Magnus the Red, Ahriman's deepest flaw is hubris. His mistaken belief in casting the Rubric to cure his Legion of their curse has seen him exiled. Though spurned by his kin, Ahriman has not given up on his quest to restore his brothers from the fleshless husks they have become, and he will brave the worst horrors of the galaxy, and the Eye of Terror itself, to obtain the knowledge to achieve it. For to bring about salvation, Ahriman must risk his own further damnation and the wrath of his primarch.
