In a magical kingdom, there lived a calm wolf named Fen. He had soft grey fur and kind yellow eyes. Every morning, he walked to the Whispering River to drink. The water sang a quiet song. Fen loved to listen.
One day, Fen found a small blue stone near the river. It was the Moonstone, the kingdom's most precious treasure. But then a strong wind blew, and the stone rolled away. Fen looked under a bush, but it was not there. He looked behind a rock, but it was not there. He felt worried.
