The classic fantasy knight is a wonderful invention, simple in design and easy to write. They are heroes of the battlefield, loyal to their kings, and there is a lot we can learn from the Middle Ages by reading about them. Generally speaking, however, they are very far from the real medieval knight and if they were presented more realistically we could learn a whole lot more. Not every knight was a hedge knight or a knight errant. Most of them had their sh*t together. So how can we make our fantasy knights more like the real knights of the Middle Ages?
