So, what have we got thus far? 

I see a couppla Astartes here, and a potential other few Inquisitors, anything else?


EDIT:


Righto, a question on two options.

Numero Uno - Would I be able to go with a Xenos, as part of a retinue (sanctioned xenos), such as a Kroot mercenary or such?

Numero Dos - An Officio Assassinorum representative, probably a Callidus Assassin?

Apart from that, I'd be happy to roll with another Inquisitor, if such is the Emperor's will.
