Vaerndoun

A network of interconnected Underdark caves stretching 100 miles northeast to southwest with the centre point directly under the city of Torsch in south eastern Sespech. Many, but not all of the caves are filled with water.

Vaerndoun is the site of a two week trade fair at the beginning of Alturiak hosted by mind flayers who refer to themselves as, and claim to be from, a hidden realm called “the Asglyth”. The fair, called the “Eleave” in the drow tongue is visited by agents from all over the Underdark as long as they provide the admission price of slaves for the illithid to feed on.
