You should already know Odin's origins as a son of Borr. However, when he felt his worship was waning at around 300-1000 CE, he started acting as a way to hold onto a bit of power by becoming somewhat of a "spirit" that would be believed in no matter what. This "spirit" is what has now become known as Santa Claus. Although he prefers the name Sinder Klaus for this persona, ultimately he doesn't mind, because now so long as there are still children, there will still always be people that believe in him (and in a way worship him)



He is designated as the angel of charity.



And if you're wondering which Raven is which, the one on his shoulder telling him secrets is Huginn, and the one sleeping on his hat is Muninn.
