As a question, who's going to be playing Big E himself? It's just that, I was hoping to develop my Primarch to closely interact with The Emperor. Essentially, I wanted him to start out as a brutish, kill-happy, rebel against authority. Typically, the kind of Primarch that would typically fall to Chaos in this situation.

Anyway, I like the idea of playing a brutish primarch that The Emperor decides that he is going to sculpt into a proper son that he can be proud of... And succeeds. I was planning on my Primarch eventually progressing to the point where he could be compared to the Rogal Dorn of this universe.
