Yar Kanti Islands
A long chain of over a hundred jungle-covered islands in the southeast sea between Sarborea and Nurdug, home to a civilization of Yuan Ti, who live all across it in many cities centered around temples devoted to their Snake Gods. The capital is Sslak. Other key cities include Zessah, Ektlieh, and Szatstliss.
The Yuan Ti engage in some trade, but mostly keep to themselves, save for their antagonism with Thulok Karn of Sarborea, whom they accuse of being a blasphemer for claiming to be blessed with his sorcerer powers by the Snake Gods. Impossible, say the snake men.
