Urchin's Maw

Located in the Arcadian Ocean west of Acisazi and northwest of the Dismal Nitch,✝ the entrance to the underwater cave known as Urchin's Maw gapes from the side of the continental shelf, overlooking a precipitous drop into the inky depths below. It earns its name from the riot of sizable deep sea urchins that dwell on the rock face surrounding the cave entrance.
