Okay, so hear me out. Harald Hardrada apparently served the Byzantine Emperors as part of the Varangian Guard, from 1034, to 1042. Because of his claim on the throne of Norway, Harald asked the Byzantine Emperor to let him go back to Norway to claim his throne. The Emperor refused, but Harald escaped anyway, and took control of Norway.

But what if Harald, for some reason could not go back to Norway, and decided to take the Throne of Ceasars for himself instead? Could he be successful, and if he succeeds, what will be the greatest effects on the Empire?
