Yuan-Ti

Yuan-ti were originally humans who transformed themselves into serpent folk through ancient rituals worshiping the great serpent god Sitherak, the god of venom and sacrifice. Most yuan-ti were corrupted into monsters by those rites, but some yuan-ti instead became a new people who mix characteristics of humans and snakes. Blessed with resistance to magical and poisonous effects by the rituals that created them, each of these yuan-ti manifests their serpentine heritage in a variety of ways: a forked tongue, snake eyes, smooth scales, or some other ophidian characteristic, in some cases their legs are even replaced by a serpentine tail. However a yuan-ti looks, they have the power to pursue great good or evil in the multiverse. The serpent creatures known as yuan-ti are all that remains of an ancient, decadent human empire. Ages ago their dark god taught them profane, cannibalistic rituals to mix their flesh with that of snakes, producing a caste-based society of hybrids in which the most snakelike are the leaders and the most human-like are spies and agents in foreign lands.
