It really should. I actually can see castor and Streban getting along precisely because of that, and they both share a well-developed love of fucking people up with sharp, pointy objects. Streban is really a 'lead from the front with a big-ass blade in hand and an army of minions at your back' kind of dark lord. Even if he had an awesome fortress of doom, he'd never be in it because he's too busy running around kicking asses, reaving souls, and fucking bitches. In some cases, all at the same time.
