Loki is the Norse god of mischief, as well as of fire. He is the son of two giants, Fárbauti ("cruel striker") and Laufey (or Nál which means "needle", implying that she was skinny and weak.). His two brothers (who were to be beside him in Ragnarök) are Býleistr (bee-lighting) and Helblindi (All blind or hel-blinder). He is referred to as the blood-brother of Odin. Loki becomes harbinger of Ragnarök and the father of the three chaos monsters: Fenrir, Jörmungandr, and Hel. Loki's mischief and intellect is not to be underestimated, as he is ultimately, although indirectly, responsible for the deaths of Baldr and Thor, which were caused by Höðr and Jörmungandr (respectively).
