Cloaca Maxima is the second dungeon in Ys IX: Monstrum Nox. The dungeon can be entered before Adol recruited White Cat; however, its entrance is blocked with a vertical wall that requires White Cat's gift to traverse.
The section north of Boss room is accessed in the prologue, where Maretudo is fought in the same boss room as Dragia Haman.
