Assassin's Creed: Valhalla - 10 Real-Life Viking Legends Who Should Appear

10. Ivar The Boneless

Known to fans of the show Vikings as the youngest son of Ragnar and Aslaug, Ivar was a real historical figure who gained his nickname either because his legs were weak or, according to some scholars, because he was impotent and therefore figuratively "boneless."

Whatever his impediment, it didn't stop him from becoming a great leader and conquering much of Anglo-Saxon England. He was renowned especially for his cunning and mastery of battle tactics.

He could also be brutal even by Viking standards, reputedly favoring execution by "blood eagle," the process of opening up the victim's ribcage from behind and pulling their lungs out to resemble a pair of wings. Ouch!
