highly likely for a no On that azathoh, Look To a few pages back on what he could say we could play, Most of us usally have to be a Neutral, Or imperial Party, meaning no chaos, Falling to chaos in the rp maybe possible but not likely unless our world actually has a artifact of chaos on it. Talk to ur GM but this will likely be imperial. Also he said no inqustion or high Ranking institutions that would be in war. Like sisters of battle, astarte, Inqustion. Look to the Eclesarchy, mechincus, Imperial gaurd, Imperial navy, Arbites, as examples of what you can play. also no psykers are a thing.
@Azathoth If you are interested beyond chaotic matters, might I suggest a non-military role? In an RP such as this one, you're bound to have your hands full with civil service, and there are a lot of soldiers already.
