Odin knows many secrets. He gave an eye for wisdom. More than that, for knowledge of runes, and for power, he sacrificed himself to himself. He hung from the world-tree, Yggdrasil, hung there for nine nights. His side was pierced by the point of a spear, which wounded him gravely. The winds clutched at him, buffeted his body as it hung. Nothing did he eat for nine days or nine nights, nothing did he drink. He was alone there, in pain, the light of his life slowly going out.
