Fae (mythology)
The Fae are otherworldly fairy creatures in Glannish mythology that are believed to be either mischievious or overtly malevolent. According to Glannish mythology, the fae live in a parallel plane of existence and can cross to Earth at will; usually to cause trouble. Disappearances are often domestically attributed to the fae in Glanainn, even in the present day. Among foreign nations, and atheists, however these disappearances are understood to often be attributed to the authorities of Opthelia, who are known to interfere in Glanainn even though it is nominally autonomous.
Origins
Characteristics
Most fae are said to be "uncannily beautiful", according to the pivotal text Mythology of Glanainn: Fae and their Realm which discusses Glannish mythology in depth. However, they are not to be judged by their appearance, as underneath their beautiful exterior can lie "cruelty and evil". Fae are said to range from slightly mischievous but fairly benign all the way to unspeakably evil; with these malevolent versions playing a role equivalent to Christian demons in the local mythology. Many, but not all fae can fly; and there are said to be numerous types of fae, equivalent to the range of animal species in the mortal realm.
Types
A number of types of fae are alleged to live in the Fae Realm - the parallel plane of existence that fae originate from. These range from human-like fae who can blend in with mortal humans by casting a spell on their pointy ears, to shape-shifting fae that can change from human form to one resembling a domestic cat.
