The Primarchs edited by Christian Dunn:
Created in the Emperor’s own image, the primarchs had long thought themselves to be princes of the universe and masters of their own destiny – they led the Space Marine Legions in glorious conquest of the galaxy, and no enemy of the Imperium could stand against them.
