Odin
Odin was the Aesir tribe's monarch and the deity of battle and earth, as well as the god of the sky, knowledge, poetry, and magic. He was a shamanic enthusiast of ecstasy and trance, and often 'effeminate' to humiliate the Viking fighters who favored their manly side. His solitary, piercing eye is among the most distinctive features of his look. His other eye hole is devoid of an eye — the eye it previously contained was sacrificed in the sake of obtaining wisdom. He relinquished it in order to drink from the Spring of Enlightenment.

On another time, Odin hung from the tree Yggdrasil for 9 days and nights, taking no sustenance from his friends and dedicating himself to himself, until he recognized the runes, the ancient Germanic alphabet believed to hold many of existence's deepest mysteries. Odin often emerges as the head of the Wild Hunting, the winter sky's ghostly march of the dead. He travels on an eight-legged horse and is accompanied by a crow and a wolf, which provide him with knowledge on what is occurring in every part of the planet.
