Odin

Odin was the king of Asgard, and the ruler of the 9 realms. While he was a wise king, and Asgard prospered under his rule, he was a cruel, paranoid man that would punish even minor offenses against him. His Night Ravens acted as a secret police that would spy on the denizens of Asgard, and he was fond of feeding those that doubted his rule to his pet wolves.

Biography
Odin is the firstborn son of Borr and Bestla, and has 2 brothers, Vili and Ve. In his youth, he and his brothers killed Ymir, presumably using the Ancient Speartip, and with his death united the Aesir tribes and crowned himself king of Asgard.

Odin's firstborn son was Thor, the only child of his first wife, Fjörgyn. Fjörgyn died during childbirth, and her death greatly affected Odin, who never forgave Thor for the death of his mother. He became obsessed with Seidr, magic that could foretell the future, and sacrificed one of his eyes to Mimir to learn how to practice it. In his visions, he saw his own death at the jaws of Fenrir, and began an endless search for knowledge that could save him.

In addition to Thor, Odin bore sons with Giantesses in the hopes that they would be strong enough to protect him. Vidar was born to Grid, and Tyr was born to an unknown mother. Odin ordered his children to bind Fenrir so that it may never harm him, and while the binding was successful, Odin feared that it would not be enough.
