[@Lurking Shadow] That clears things up, then. I actually think that D&D has a similar creature, the Yuan-Ti. They’re basically what you just described, snake-human hybrids who used to rule the world and are plotting to take it back, and some of those also can take on a near-human appearance to infiltrate society. The main difference I see is that Yuan-Ti are very much Aztec in their aesthetics and come in a variety of hybrid forms, I dunno if Lovecraftian Serpentfolk are the same.
