Rângilan is an undersea depression cut with numerous rifts. It is twenty miles south of Paradomea City. The maze of rifts are home to many deep sea creatures and a few bands of sahuagin. Before the Sea Devil War, this area was home to a vast horde of sahuagin. They dwelled in an ancient Durkoth city called Limac-Nîr.
In the Durkoth Descent, the Durkoth from the Spire of Neld-Rac came to this area and subjugated sahuagin by the thousands. Sahuagin scratch coral of that time say that a mad race of humanoids dwelt in this area and spread chaos and dissent.
