That night at the great castle, the storm lord and the knight of
skulls and kisses each swore they would unmask him, and the king himself
urged men to challenge him, declaring that the face behind that helm
was no friend of his. But the next morning, when the heralds blew their
trumpets and the king took his seat, only two champions appeared. The Knight of the Laughing Tree
had vanished. The king was wroth, and even sent his son the dragon
prince to seek the man, but all they ever found was his painted shield,
hanging abandoned in a tree. It was the dragon prince who won that tourney in the end.
