"Horde from the East" question

[unic]

On the "Horde from the East" card, it refers to "in a free Region".

What does this mean?

I can see two possible interpretations:

A free region = a region with no units or characters in it.

or

A free region = a region which has not been conquered by the opponent.

Which is it? Or is there some other meaning to the term "free region"?
