Loki, the Trickster, challenges the structure and order of the Gods which is necessary in bringing about needed change. In the Prose Edda Snorri Sturluson writes that Loki:
“Is handsome and fair of face, but has an evil disposition and is very changeable of mood. He excelled all men in the art of cunning, and he always cheats. He was continually involving the Aesir in great difficulties and he often helped them out again by guile.”
Neither an Aesir or a Vanir, he is the son of two giants and yet the foster-brother of Odin. Loki embodies the ambiguous and darkening relationship between the gods and the giants. He is dynamic and unpredictable and because of that he is both the catalyst in many of the myths and the most fascinating character in the entire mythology. Without the exciting, unstable, flawed figure Loki, there would be no change in the fixed order of things, no quickening pulse, and no Ragnarok.
