A knight left the castle one day on his horse to fight the Crusades, armour shining, plume in his helmet, lance and sword at the ready. The knight disappeared on the horizon, and did not return for week after week, month after month, year after year, until the people inside the castle almost forgot him.
One day, they spotted a tiny figure coming toward the castle, and as it came closer, the people in the castle realized it was the knight returning. The king came down and the people gathered. As the knight drew near, they could see that his armour was dented and his lance broken from many battles. His face was crusted with blood, and his horse collapsed near death at the castle gate.
"I have conquered your enemies to the West", the knight said.
"But I have no enemies to the West", the king replied.
"Well you do now."
