Odin - the Chief God
Odin was the chief god. He was the most powerful god in Asgard.
Odin was the grandson of the very first Aesir, Buri.
He was the son of Bor and Bestla. Bestla was a Jotun woman.
Odin was married to Frigg. Together they had the sons Balder and Hod.
He also had children with other women. Odin and Fjorgyn had a son named Thor.
Odin and Grid had a son named Vidar.
Thor was the strongest god in Asgard. Vidar was the second strongest god. Fjorgyn and Grid were both Jotun women.
When Balder died, Odin had another son with a Jotun named Rind. The son was named Vali and he grew into manhood in only one day.
His mission was to take revenge for the murder of Balder.
Vali killed his blind half-brother, Hod. Hod was forced to join Balder and Nanna in Hel’s World of the Dead.
The world was created by Odin and his two brothers, Vili and Ve. Read about it on the page named Creation Story.
Odin - the One-Eyed God
It is easy to recognize Odin. He is the god with only one eye. 
It was told that Mimir was the wisest of them all. Mimir guarded a magical well, named Mimir’s Well. It was told that anyone who drank the water from that well would gain the wisdom of Mimi.
Odin was willing to go to any length for a slip of water from Mimir’s Well. Nothing could stop him. When he was offered to drink water from the well in return for an eye, he didn’t hesitate. Odin sacrificed an eye and rejoiced as he drank the water of wisdom.
That is how he ended up not only being the wisest god in Asgard, but also the one-eyed god.
Odin hung himself for nine days
Odin made another huge sacrifice. He hung himself in Yggdrasil, the tree of life. For nine days he hung in the tree.
By sacrificing himself in this manner, he gained power over the runes and all their secrets. The meaning of the word “runes” is secrets.
Two Ravens
Odin owned two ravens. Their names were Huginn (thought) and Muninn (memory). The two ravens flew out over all the worlds every morning and returned every evening.
When they returned, the ravens whispered all that they had seen and heard to Odin.
Two Wolves
Odin also owned two wolves. Their names were Geri and Freki. Odin gave the wolves all his food from the table. Odin did not need any food to survive, wine and mead was quite sufficient to keep him alive. Geri and Freki followed Odin wherever he went.
Sleipnir - the Eight-legged Horse
Odin had a gray horse named Sleipnir. This was a magical horse with eight legs. Sleipnir could just as easily gallop through air as on land. The eight-legged horse was given to him by Loki.
In his possession Odin had a spear named Gungnir. It could hit any target. Gungnir was a special spear indeed. Gungnir means “the swaying one”. It was made by the dwarfs.
Draupnir - the Magic Golden Ring
Draupnir was the name of the gold ring belonging to Odin. Every ninth day eight new rings would drop out of Draupnir.
The eight new rings were of equal quality as Draupnir. Needless to say, it was the dwarfs who had made this spectacular gold ring.
Gladsheim
The largest house in Asgard belonged to Odin. It was named Gladsheim. Gladsheim was covered with gold, on the outside as well as the inside. The name “Gladsheim” means “the bright home”.
Odin had a thrown. When he sat on his thrown, he could see throughout all the different worlds.
Odin: the Father of the Slain Vikings
Odin was often called “father of the slain”
Half of all the men who died in battle would be taken to Valhalla, the hall of the slain. Valhalla belonged to Odin. The other half those who died fighting were sent to Folkvang.
Folkvang was the home of the goddess named Freyja. The goddess Freyja had first chose of who she would receive.
Valhalla was a huge palace with 640 doors. Every single door was extremely broad, 960 men could walk side by side at the same time through a door of Valhalla.
The Valkyries
The slain men who came to Valhalla were fetched by the Valkyries.
The Valkyries are women figures who are fully armed and rode their horses over the battle fields and brought dead Vikings to the afterlife at Valhalla.
Only the bravest and most fit men who died on the battle fields were chosen by the Valkyries. 
The name “Valkyries” means choosers of the slain.
The Valkyries served the men mead at Valhalla and joined them for dinner. The Valkyries were described as very beautiful maidens.
In Valhalla
In Valhalla the men would amuse themselves by having fights with each other. If anyone got killed during these fights, they would come back to life in the evening. So the fighting could continue until Ragnarok. The Valknut Odin will die
Every evening they would have a feast. The boar name Saehrimnir would be slaughtered and cooked. After they all finished eating, Saehrimnir came back to life and ready to get slaughtered again the next evening.
In Viking times devotees of Odin used the symbol called the Valknut.
The Valknut is the made up of three interlocked triangles.
It means “the knot of the slain” and symbolized the slain warriors who died fighting and were fetched by the Valkyries and transported to Valhalla.
In the end Odin will be killed during Ragnarok.
Ragnarok was the doom of the gods, the end of the world.
The Fenrir Wolf will kill Odin. Vidar will take revenge and kill the Fenrir Wolf.
Vidar, son of Odin will survive Ragnarok.
