[Cainehill]

Some of the diplomacy is simply knowing that even those nations with whom a player hasn't spoken to, can't freely attack them without going rogue.

In any case - I expect things may be getting more lively, as I expect at least one of three nations will be unhappy with my eating their knights. ( Just bellyflopped into an independent province half a dozen away from my nearest lands; while I'm sure someone may've been counting on it for their own, I have taken advantage of the charter stating that such provinces are first come, first claimed. )

As far as "not seeming to have any support at all", you said several wyrms had given you positive responses?
