I'm going to have the RP take place on a planet that has been victim of a devastating war, and basically in the last remaining hive it's no mans land and everyone is fighting for control of it, you will have the Inquisition trying to claim it in the name of the Emporer and people like the Arbites trying to protect it from falling into the hive gang's hands.

It's a basic scenario of allies fighting weach other (As they always do in the actual fiction)
