Odin, Frigg, Thor, Loki, Balder, Hod, Heimdall and Tyr are the most elevated representatives of Æsir and are known as the main gods. The second clan, Vanir, contains the fertility gods and count Njord, Freyr, and Freyja as their most notable members.
The Vikings had their own belief system, Norse mythology, prior to Christianisation. Norse mythology centered on gods such as Odin, Thor, Loki and Frey.
Odin was one of three brothers that were responsible for taking down Ymir, a hermaphrodictic. Giant and source of the Earth according to Norse mythology. This feat alone should be enough to earn him the status of being one of the most powerful Norse gods ever.
Odin gave up part of his vision to gain wisdom. Symbolically, the meaning of the sacrifice is fairly surface level: one must often make great sacrifices to gain great knowledge. The specific sacrifice of vision may also suggest that looking within instead of without can grant wisdom.
Odin is the god of war and of the dead. He rules over Valhalla – “the hall of the slain”. All Vikings who died in battle belonged to him. They were collected by his female handmaidens, the valkyries. Odin was first and foremost worshipped by kings, warrior chieftains and their men.
Odin, the god of wisdom, death, battle magic and more is neither entirely good nor is he fully evil in Norse mythology. Odin is a warmonger and as such a bringer of death on the battlefield. In contrast, Odin created the first humans from which all life was on Midgard (Earth).
In Norse mythology, Odin is the god of wisdom, knowledge, poetry, runes, ecstasy, and magic. As a war god, Odin is the god of battle and death. Odin is described as traveling through many realms or worlds, winning every battle.
Such Power and Strength is Odin. He is also known to have the ravens around him as they tell Odin everything they see and hear. Odin sends Huginn and Muninn out at dawn, and the birds fly all over the world before returning at dinner-time. As a result, Odin is kept informed of many events. High adds that it is from this association that Odin is referred to as "raven-god".
He sacrificed his eye in Mimir's well and he threw himself on his spear Gungnir in a kind of symbolic, ritual suicide. He then hanged himself in Yggdrasil, the tree of life, for nine days and nine nights in order to gain knowledge of other worlds and be able to understand the runes.
Connecting with Odin is for Protection, Strength and Divination of Runes and is very Powerful!
