Magical creatures that originate from fairy tales are colloquially known as the Fey. Elves, dwarves, fairies, angels, and demons are all a part of this category. They’re a varied group who tend to have commonalities more than anything else. See Appearance Rules for details.
Beyond their appearance and the presence of aether in their body, the Fae have equal capabilities to humans. These characters tend to find wounds from iron to be slightly more painful, though they take no extra damage from it; it’s suspected that this is caused by the aether in their body reacting to the metal.
