Successor game rules, draft one.

For the rest of us, I think Zim will create some RBGs and then when we have picked, use the teleport to place them in the provinces that people want to be placed in. I guess we need to allow some real time interval for Houses to try to recruit RBGs before location is finalised.

Yep, I think that's the best method. In LotR, I allowed all players to pick any settlement owned by the faction as the starting point for a new avatar and simply teleported them to whatever place they chose. Beyond the obvious benefits to roleplaying of being able to start in a particular spot instead of having to cross half the empire to get there, this also allows the RBG recruitment to be done in any sleepy, backwater settlement so that it doesn't risk interfering with normal recruitment that might otherwise be going on at the chosen destination.
