About the Mollys:
I might be wrong, but is New London the only place outside of the edge worlds where both Corsair and Outcast NPCs both spawn?
This is going to drive the Mollys one of two ways, imo. Obviously they hate the corsairs, that's not going to change.
Now, with the Outcast presence in Bretonia, they can really go one of two ways.
One, allying with the outcasts to drive the corsairs out.
Two, telling them both to gtfo.
Closer ties with the Hessians might cause the second ideology to travel to the Mollys via osmosis or whatever. Rheinland unlawfuls are all connected to each other, but stand apart from the sair/oc thing (No NPCs in rheinland I don't think). This will probably appeal to the Mollys (I would assume) and an alliance with the Hessians might teach them how/help them/etc/make this more achievable/attractive for them.
