Matt, Alright man so here's my problems. First problem Your bodyguard, first I'd rather you not have a death watch marine as a bodyguard mainly because that's you controlling a fairly powerful PC and a very powerful NPC so I'd prefer if you grabbed yourself maybe a stormtrooper for your retinue. 2nd problem is your bodyguard is of the Ordo Xenos when you're Ordo Hereticus? That is highly unlikely for that to occur considering a ORDO xenos member of any sort wouldn't very likely follow around a witch hunger cause well.. he'd never come across Xenos. Arco Flagellant would be okay as well or even a Callixus assassin etc.
