Ancient Serpent = Dragon

Dragons would still fit a lot better with the folk creatures instead, one note for it; dragons, unfortunatly, can't convert people like Vampires, Werewolves, Skinwalkers, Arachnes, instead they are more like the Shapeshifters linked to just one form. These dragons are way too fairy folk, take Merlin and Dragonheart for example, they are almost always described as part of the old terrastiels. The only other few cases are for religious purposes (Michael/Sigurd puting the sword through Lucifer/Fafnir).

Everything else is fairy tale based, like that episode with the little girl in a coma making classic Grimm Tales become real.
