ODIN is the chief god of Norse mythology and is associated with wisdom, war, death, poetry, and magic. Thor is ODIN's son and is associated with strength, thunder, storms, and protection. Both ODIN and Thor are seen as powerful figures in Norse mythology and are often referred to as Valhalla Bigwigs.
