Speaking about dragons, wasn't there some talk about recruiting monsters, and rarely, a dragon, to fight alongside you?
Any-thoughts on how to gain such creatures?
Also, I think that certain super-enemies could allow for a team-up (at least temporary) if the right alignment/religious pre-requirements were met ... then you could at least TALK to the darn thing, and it would give you a quest to complete, and if you complete the quest it would team up with you.
Preferably talking with the beast would prevent it from attacking you for at least 10 rounds or so, or deflect it towards the next closest civ.
This deflection could theoretically slingshot an evil beast through an evil coalition, until it finally attacks a goodly civ. Alignment could be affected by both race and religion, and possibly by the abilities and actions of the Sovereign.
Something akin to Civics, combined with something akin to broader alignment, combined with religions, combined with starting weights for wether you are human or fallen.
Im sure there are various cultural variations separating the different sects of humanity, and different sects of fallen, each with different alignment pre-weights.
