Yuan-ti

Sapients usually resembling humans (in the most common, pureblood form) but with various snake-like features, such as scales, snake eyes, fangs, forked tongues, or, in extreme forms, snake heads, arms, or lower bodies. The ancestors of the Yuan Ti were humans, but they fell into the transformative worship of the Snake Gods.

On Jesenreth, they control the Yar Kanti Islands.
