The man guarding the castle is a brave and bold KNIGHT. Instead of using a short weapon, like a KNIFE, he uses a sword and shield. The castle he guards has many people that WRITE stories or letters to the other kingdoms. When the guard was young, he fell and injured his KNEE. He could not KNEEL when the king made him a knight, so he sat down instead. He has been a knight ever since. TELL ME IF IT HELPS.
