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.
