Hi,

What exactly does expel do?
I don't remember the explanation on the button verbatim, but
it was something like

"expel X people to to governed settlements"

What governed settlements? Mine? Or the AI's?

The "enslave" part is kind of a mix of the vanilla RTW's enslave
with the loot from exterminate. It was easy to notice the effects.

Is there still an exterminate option available later in the game?
