In 484, King Arthur participated in a heated battle with the Saxons along with his loyal knights, but the battle wasn't going in the Britons' favor. The king told his knights that help was on the way. While his knights didn't trust the help he said was coming, the king believed in the old sage. Help did arrive in the form of a giant three-headed fire-breathing dragon, who swiftly decimated the opposition. In the wake of their victory, Arthur held a toast to old and new comrades. In the 21st century, Viviane Wembly believed that King Arthur was more fiction than fact until her lineage was revealed to her by Sir Edmund Burton.
