Zasoa

Zasoa, unlike Roraye, is nearly impossible to reach by surface-dwellers. It is deep, deep in the ocean, a marvel of underwater magic and harmony. The entire city exists in and a part of 100 miles of magically and naturally grown coral reef. The worst crime a merfolk or surfacer can commit in Zasoa is to harm the coral. Zasoa is almost entirely off-limits to outsiders, and is ruled by the third prince of the royal family.
