The King of the Fairies and the husband of Titania, the Fairy Queen. He rules over moonlight, dreams, and all fairy rites. He first became widely known when he appeared as a character in Shakespeare’s "A Midsummer Night’s Dream, but appeared earlier in the 13th century French epic "Huon of Bordeaux". In some stories, specifically in "Huon of Bordeaux", it is said that he is the son of Morgan le Fey and Julius Caesar, believed to have been born sometimes after Caesar’s defeat of Pompey.
Although he has the face of a handsome young man, a curse has made him no taller than a young child that he received shortly after birth. However, the curse gives him eternal beauty. He is polite and sometimes even friendly towards humans, however he can be a selfish, short-tempered ruler, often falling in love and flirting with human women, only to be restrained by his consort Titania. The two are said to have once lived in India, and would cross the sea to Europe at night to dance in the moonlight.
