My Awu Chiefdom is completely neutral to both pro and anti-terran (though, if they were absolutely pushed into war, they'd probably air on anti-terran). We could have the peace conference there. But they're only that neutral because of their lack of development and poverty level...it would be sort of like a UN conference held in Botswana. But that said, their new leadership is trying to get Awu more involved in the galactic stage anyways, so really it's up to you guys, if you want I'd be happy to host it.
