The fellow who came into possession of me was instantly enchanted because I have the power to make his every whim a reality.
Unfortunately, he lost me, but after a long journey (all the way to the sun and the moon!) he found me again. He used me to wish the thief and his whole family to the bottom of the Red Sea.
Quite clearly, my owner will go to the ends of the earth to have his wishes granted, but I do wonder what he would do if he didn’t have me. He is positively addicted to having his wishes granted instantly, which makes him the most powerful man on earth. But he has no real powers of his own!
