[@Dead Cruiser]I didn't know Sanguinius that well since I honestly never gave that much of a shit about Space Marines or the Primarchs or the Horus Heresy. I looked into more of the Astra Miliwhatnow and the Orcs.

One idea could be a kindhearted knight whose secretly a vampire or something like that. Again as I've said, playing an Incarnate would require an exceptionally well written CS and a good deal of time commitment of which I remember you saying you were tight on.
