Those are mobs on Floor 1, Field Bosses guard the entrance to Labyrinths. Sub Dungeons can have different mobs if you so choose.

Imma do my post within the hour. It will set up the Labyrinth(I'll create a list of mobs in the Labyrinth), and it'll end it with advancing to the meeting. You all can be at the meeting after that or be informed via a mass message.
