In Norse lore, the figure known to possess the knowledge of runes is Odin. As a primary god, he sacrificed much in his pursuit of wisdom, even giving up his eye for insight into the mysteries of the universe. His mastery of runes not only symbolizes knowledge and the magic of language but also represents the interconnectedness of spirituality and the physical world. Odin's association with runes signifies the importance of written communication as a means to access deeper truths.
