Yuan-Ti Pureblood

The Yuan-Ti are said to be the daughters of the Medusa.
They lack most common human emotions and will react mostly on pure logic and intuition. They are often found guarding the statues created by the Medusa, but some of them have ventured out.
Not all bad There is even talk of a small city built on the ruins of a lost civilisation that thrives through trade with the Triton and Tortles.
