Loki is a god in Norse mythology. He is the son of Fárbauti and Laufey, and the brother of Helblindi and Býleistr. Loki is married to the goddess Sigyn and they have two sons, Narfi or Nari and Váli. By the jötunn Angrboða, Loki is the father of Hel, the wolf Fenrir and the world serpent Jörmungandr. In the form of a mare, Loki was impregnated by the stallion Svaðilfari and gave birth to the eight-legged horse Sleipnir.
