The underground air pressure in this area is such that one can walk into the undersea waters of the Sea of Mourning. Some of these openings to the sea lie along walls where one must walk or climb up to them. Certain areas feature ramps or stairs ascending up to these entrances. These were constructed over millennia by sahuagin raiders emerging from the undersea canyon Burrogral. From Okaaz Piin, the sahuagin raid the frontiers of Zoethall and Qya-Qhar.
