Odin is depicted as a Warrior God. On his helmet are 3 Magical Runes:
Ken, Rune of Passion: Guidance; Creativity, and the Quest for Truth.
Tir, Rune of Victory: Justice; Honor, Leadership and Authority.
and Othala, Rune of Heritage: Physical and Spiritual.
In the Viking Sagas he is depicted as having one eye, carrying his spear Gungni, and wearing a wide-brimmed hat and cloak when he appears to his people. He is said to be the template for the Wizard Gandalf in 'Lord of the Rings'.
In his Kingdom, Asgard, he has his Ravens: Hugin and Munin who fly throughout the world and bring him back news each day. He also has two pet Wolves: Freki and Geri. Odin's horse is the great eight-legged Sleipnir, best of all steeds.
Odin sacrificed himself in order to bring the Magic of Runes to the world: pierced by his own spear he hung from the World Tree Yggdrasil until he received the Knowledge of the Runes.
