Before I realized that, I made a city whose buildings completely blocked a narrow passage between mountains, and then discovered that units could only leave on one side of said passage. So that's almost certainly going to be changed at some point before release.

That doesn't seem like the full story, though, since when my various sovereigns did have mana greater than 0, it was usually not the same amount as their essence.
