Odin, also called the All-Father by worshippers & Havi by the Æsir, was an Isu who became a widely revered god in both Norse and Germanic mythology. The leader of a group of Scandinavian Isu called the Æsir, he was known in Norse mythology as the king of all gods, associated with wisdom, healing, death, knowledge, and war. Along with being the original owner of the spear Gungnir, he was also the father of Heimdall, Baldr and Thor, the warrior god of lightning and thunder.
Odin is also referred to as Havi in Old Norse, meaning "High One". The Anglo-Saxon pagans referred to him as Woden in Old English. Among his other epithets he is called; The Hanged-God, Shield-Shaker, Graybeard, the Mad One and Wanderer. Andhrímnir referred to him as Lord-Keeper.
At some point, Odin arranged for Fenrir, the illegitimate son of Loki and Angrboda, to be imprisoned on grounds that Loki deemed false. Subsequently, Loki killed Odin's son Baldr by poisoning his food with mistletoe berries. Odin stood over his son and grieved his death while Loki watched from afar. After learning who was responsible, Odin ordered Loki be apprehended to answer for his crimes.
After this, Odin met with the Mother, who revealed to him that she, Jupiter and Minerva were working on the supercomputer Yggdrasil as a seventh method of salvation to avoid the Great Catastrophe. The method itself was similar to an earlier attempt, in that the Isu DNA would be uploaded into the human genome. Odin then began searching for a way to resurrect his son.
When the Great Catastrophe came, Odin summoned his trusted eight to his secret chamber and uploaded themselves. He stated that none could follow them, especially Loki. He broke his mask and led the eight to face their end. Millennia later, Odin was reincarnated as the Raven Clan shieldmaiden Eivor Varinsdottir.
At some point, Odin disguised himself as a beggar and plunged a sword into a tree called Barnstokkr, stating that whoever was able to pull it free would receive it as a gift. Only the warrior Sigmund proved able to do so, and subsequently claimed the Sword as his own.
