Odin it’s a descendant to Evior of The Raven Clan and an Isu of The First Civilization

I doubt it, given that he was so obsessed with coming back to life that he probably didn't plan anything else. I feel that Odin will probably be a stepping stone to a new Isu threat though, given that Basim will probably be the new modern day protagonist.

I doubt that Basim would be the new protagonist. Elijah, Desmond's son, is out there with the koh-i-noor. or Callum? u Owen?

Odin absolutely is a villain. He tried to change his fate so he lived instead of Fenrir(son of Loki) and then punished Loki for retaliating and trying to prevent his sons death. Not just Fenrir but also Jormungandr and Hel. And that’s just on the actual mythology. If you’ve gotten all the little memory things you learn along the way via the Isu Aletheia and Loki that Odin already killed Fenrir. On top of that Odin tries to make Eivor make some selfish decisions(Don’t quote me on that I haven’t played in a while but I’m wanting to replay). So hell yes Odin is a villain
