"When our heroes settle down, what do they bring home with them from their journeys? The Emperors of Byzantium were defended by Vikings, many of whom lived out their lives in the Varangian Guard, and some argue that Marco Polo and other silk road traders brought pizza and pasta to Italy from China. What examples of religious, cultural, and technological transfer can we think of in fantasy, and what would we like to see?"
I am having the damnedest time thinking of examples from fantasy rather than history (or historical fiction, which is not always the same thing). Help me out here.
