Well, that depends on how the RP overall is gonna work out. IF you want to do it like I said, would be best to figure out some arc to connect things with, and then try to introduce some of it at the start.
My idea, if you want to steal it: a big swanky casino-type place, full of criminals, all there to talk crime stuff.
I do have overall plans and connections in mind already. The things I suggested fit into that. I would prefer not to do a scenario that limits the sort of people who could reasonably be involved.
