the son of jotunns Farbauti and Laufey and blood-brother to Odin, Loki is by nature ambiguous. associated with lightning, wildfire, and volatile chaos, Loki sometimes helps the Aesir and sometimes causes them problems. a talented shape-shifter, he earns the kennings of Silver-tongue and Lie-smith. at first, he appears as a mischievous, handsome troublemaker, but as time goes on, his tricks darken to outright murder. as punishment for the death of Balder, Loki is chained to three rocks in a cave on Earth with a poisonous serpent fastened over his head. his wife Sigyn holds a basin to catch the venom, but she must leave at intervals to empty it. then the poison falls on Loki’s face and he writhes in pain, causing earthquakes. he will be freed at the onset of Ragnarok and the end of the world.
