Odin
Odin was the former Alfather of the Gods; the King of Asgard and all who dwelt there.
He was instrumental in all aspects of the worlds, from Asgard to Midgard, to Nifelheim and the
realms of the Jotun and Alf, and has places in the stories of Fenrir, Mimir, Freya, Freya, Thor, Loki, his son Hod and many others. He was father to many more, first amongst which was his son Baldr, the Shining One. Though he strayed often; as the Gods are want to do, he never-the-less was always loyal to his wife Frigg, the only one he ever truly loved.He also has two brothers, Vili & Ve.
He was killed during Ragnarok by the Fenrir wolf; this was prophesised to happen, though Odin made steps to ensure it didn't. For all his wisdom he could not see that it was his actions caused Fenrir to want to kill him in the first place.
