Sar'Rukoth

Sar'Rukoth was an island in Okoth containing a number of crumbling ruins and new, unlit domes. Each dome contained one of 18 sterile sarrukh and all of that sarrukh's servants, protectors, advisers, and entertainers, most of them being yuan-ti. They were connected by a system of tunnels that passed through various salt lakes, caves, and sarrukh tombs. The last known khuzdar, or leader of the council, was Ziss'thiss, whose influence was spread across Faerûn.
