Interesting, Pacifist and Bird might interact hilariously if the red mist of rage counts as not being able to 'see' one's enemies. But it's a straight up 1 for 1 trade and Pacifist impedes social conflict as well, so not worth it.

Mazed (Planescape or Labyrinth Empire reference? Both?) is painful in conjunction with Archival/Inheritor, but I have to pay for my overweening greed somehow. Citizen'll provide initial safety if it adapts properly to Mazed, though with a lower standard of living. Could be cut if the Tribes' strategic position is dire enough that they're relying on me, dropping Fatal Flaw. Legacy disregards incompatibility, which is great. If you can pick your predecessor, even better, Might's Overlord has obvious synergies with the Tribes and I can hope the cache comes with Cultivation resources.
