Sir Brian Flockart is a gentle knight who hates war. He doesn't much like the king, who makes war for a living, either. But as the king's battle planner, Sir Brian is told to find a reason to invade the neighbouring city of Burpington - or be sent to live with the rats in the deepest, darkest dungeon. What advice will Sir Brian get from his friend Meg, the dairymaid, and their pet dragon, Grund?
