A Sidhe (aka Fey) is a creature in the Iron Fey series. They are the faery nobality, and resemble mortals, except for pointed ears and larger eyes. Sidhe can use Glamour to change their appearance or use "magic". Some known faeries are Ash, Robin Goodfellow, and Oberon. Meghan Chase was half a faery but is now a full fledged faery queen of the Iron Realm.
