But banshees are fae so we already have fae on Teen Wolf.

(And, btw, to legitimately answer the questions: fae are a whole genre of mythical creature, mostly from the British Isles, though there's some from other parts of Europe. Fairies, pixies, brownies, goblins, banshees, leprechauns, kobolds, etc -- all fae.)
