Sailing from Emon southwest to Vesrah takes six to seven days, and involves passing north of the Hespet. Sailors usually steer clear of the area due to its reefs.
Near Vesrah, through a forest of an underwater plant life, there is a hollow underwater tower made out of yellowish-white sandstone. It is attached to the reef above by a single pillar of stonework that seems to be built or carved out of the reef. The tower contains the Aerie of Torrent, a rift to the Elemental Plane of Water, emitting a dull green, faint, sparkling glow.
