Once their was a Dragon who was sitting by the river and found a marvelous pearl that had been smoothened by the wind and water and decided to take it home and work on it .
Without sleeping or eating dragon stayed up for 2 in a half years straight making that pearl perfect and finally it was done. Since Dragon did not sleep for 2 in a half years he soon fell into a long sleep.
The queen of heaven saw the pearl and wanted it to herself so she sent her servants to go and get the pearl from the dragon.
So off the servants went to steal the pearl from the dragon. Since the dragon was still asleep the pearl was very easy to take.
Once the queen had the pearl she locked the pearl up in her chamber of treasures that needed 7 keys to open and all the keys were tied to her waist. So the dragon could never get it even if he knew where it was.
On the queens birthday she invited everyone to her party including dragon her when she was finished unwrapping her last present she said "thank you all for this nice presents but i have a treasure that out shines all of them" and unlocked the doors and brought out the pearl.
