Carved into the wall is a set of stone doors, which, when open, would probably allow you into the town. To your spell, the doors have a very light magic on them, a cantrip, probably a command activated open/close. The rest of the wall is mundane.

The two men, both human, look down from the wall. "What brings ya here, wizard?" One of them asks. The man has a very odd accent, one you cannot place. Both have bows in hand, but not drawn.
