The Last Remembrancer

In a secret fortress on the dark side of Titan, Rogal Dorn and Iacton Qruze meet with a prisoner. That prisoner has a tale to tell, of heroes and monsters, of honour and treachery, of life and death. He has stood at the side of the Warmaster himself, and he has a message for the Imperial Fists primarch. But can he be trusted? And can he be allowed to live? Rogal Dorn must decide the fate of the last remembrancer.
