Vindication
How many expansion region tiles can I add, and how do I choose which base tiles to remove?
The publisher account confirmed this in a forum reply, which matches the rulebook's four rules.

You have a lot of freedom as long as you follow the four rules for choosing which region tiles to remove (always keep the Arcane Tower, Ancient Tomb and Gaping Maw, equal numbers of Holy Spires, Forts and Libraries, equal numbers of Command Posts, Shrines and Monasteries, and at least two inns). The designer says the game is built for as much customization as possible within those rules.
