Let's Play Age of Wonders III: User Input Required

Question: Does the underground have any bandits/enemy troops that might try to enter the surface to attack us? Because the entrance looks pretty close to two very undefended cities.

Neutrals no, enemy troops yes. In fact, because Goblins are well suited to the underground, Wazuhl could move through there or... crap, that's probably where he lives. It's to our northeast, we haven't actually seen any settlements under their control, and goblins have bonuses to movement and vision underground.
