This will start out with players as a fresh, untested cell of Acolytes under an Ordo Hereticus Inquisitor, so the first few missions will be mostly unconnected with a larger plot. There'll be some hints to things to come, but you won't really see the plot threads start to form until around rank 4. 

For character creation at the base rulebook and Inquisitors handbook will be available, but Adepta Sororitas are off limits at the beginning. Other than that it's standard first level character creation. 

There'll be five character slots but if the fifth one is taking too long to fill up we'll start with four.

Also feel free to start working on and run characters by me at any point, either in PM or on the thread.
