Yeah, its kind of misleading when its like the second or third dungeon encountered.
But yeah, came in from the left entry corner. 2-3 of them with zombies.
Well no not really, this module is not built in zones, level 1 go here, level 2 go here, level 3 travel to this continent and stay here never to return to the starting location. It stops entire sections of the module being ghost towns once the new characters start to level up, and the new character being lonely when they are at different levels to the module population.
