Will we be seeing factions develop around opposed claimants to a title? If so will the player see or participate in feuds between rival factions take place in game?
This one, is probably not an explicit goal but an implicit goal. ToadyOne has spoken about the reemergence of Guild Leaders, and Religious Leaders appearing. There have been talk about, things like Traditional personality trait being contextual based on local and/or regional history. And we can extend the convo about Traditional personality trait, to other personality traits like Loyalist, or Patriots ect ect ect.
I also wanna say that Vampires can get followers when they're pretending in cities. There also Demons impersonating Gods and Mega and Semi Beasts gaining cults/worship.
So there lots of things that are in place to allow for organic formation of factions around emergent leaders. And depending on how these things get more fleshed out over time and work, you can totally get factions forming around leaders.
If it doesnt happen organically, then it might need dedicated mechanics to force it anyway, as having politcol strife within a country is a great source of narrative, and come on, you gotta have civil wars and minor fights between regions.
