For future reference on how I plan to develop /who/ for the Viti era, I am using Vitubia /who/ as a template of sorts. Any lore pertaining to territorial changes, alliances, or other diplomatic affairs is retconned out of existence, while the rest (for the most part) is treated as established canon before the Nameless One's cessation of divinity. There will be an addition or change here or there. The seers known as Morbs are an example of this.
If you have to recreate the borders manually, don't be concerned about fudging the borders a bit here or there. They would naturally be a bit porous in the current state, and most Hoomans don't do too well with borders anyway.
