The Nelanther Isles were a widely scattered chain of nearly one thousand islands west of Amn and Tethyr in the Trackless Sea. More than half the islands lacked potable water and were an unfit place to live. The hundreds of islands that could support life were fought over by ruthless pirates who tended to prey upon the shipping lines of Amn, Tethyr, Calimshan, the Sword Coast and the Moonshae Isles.
