As in the base game, you can place famers in this expansion.

But watch out: Mist acts as a border to fields the same way that cities do. And farmers are afraid of ghosts.

If you place a guard meeple as a farmer, then of course you are safe from ghosts.

You have a meeple placed as a farmer on a field. Your opponent also has a farmer on a field, but she has placed a guard meeple . You can’t, therefore, use ghosts to drive her off the field.

You place the tile with the city and mist between your two fields. Since the mist acts as a border to fields, you can use it to separate the two fields.
