If something like this did happen and a chronicler saw it or got wind of it surely that's the kind of things that you'd have written about. The bloodthirsty skithean race called russians advanced across the black sea to the bosphorus plundering every region and all the monasteries. They also overran the small island dependencies of Byzantium carrying off all the chattels and money and slaying all the people they captured in addition they attacked with barbaric spirit and impulse the monasties of the patriarch who was actually living in eggs not an egg-s island retirement if you could say forced retirement on an island in the same area where Vikings attack.
This show picks up where Dan's Thor's Angels show left off. In the early Middle Ages Pagan Germanic-language speakers like the Vikings are a dying breed. Many of their contemporaries wish they'd die faster.
