This is mostly a fluff question, but I was under the impression that the serpentpeople described by Paizo were mainly inspired by the creatures from Lovecraftian and Conan lore. In those stories it is alluded to that these creatures worship a deity known as Yig, who makes appearances in many Lovecraftian RPGs.
Since the release of Bestiary 6, it appears that Yig is now in the Pathfinder universe, which leads me to ask, is there a difference between Yig and Ydersius? Or lore-wise, could they be interchangeable?
