Okay, so giving some thoughts to each area for future reference:
Ju-Ji's Hall: It's right next to Tessen and quite small. Plus, there's a lot of factions and there doesn't seem to be a lot of misery so I think it's best to put an enclave here.
Broken Crossroads: Still right next to Tessen but quite big. There appears to be a lot of gangs which means there's social issues for us to fix. Would be good for a chapter though we will have to send some guards with them.
The Capital: To be avoided until we are ready to go into big boy politics (which we are not). Plus, it's quite far from Tessen.
The Green Dunes: COE homeland. To be avoided until we are willing to go fight them.
Slatnan's Womb: Quite close. Doesn't seem to need our help so I don't see the need to set up shop there.
Seven Silver Cathedrals: Quite close. Very low population. Would support an enclave at best.
The Read Sea: Far away. There are not a lot factions beyond the local Houses. Would be higher priority if it wasn't so far aaway.
