Óðinn is a major god in Norse mythology, known as the Allfather. He is associated with wisdom, war, and death, often depicted as a one-eyed figure who sacrificed his eye for knowledge. Óðinn rules over Asgard, the realm of the gods, and is the leader of the Aesir tribe of deities. Óðinn is also linked to poetry and magic, often seeking out ancient runes and secrets. He rides an eight-legged horse named Sleipnir and is accompanied by two ravens, Huginn and Muninn, who gather information from the world. His complex character embodies the duality of creation and destruction.
