Jon was sitting in his room thinking. He had the night to himself, and decided to think about what to wish for when he heard some knocking on his front door. He went to answer it, and saw a man in a cloak standing there.
"I want my stone." he said.
"What are you talking about?" Jon asked.
"My stone. It has my power in it, and I want it back." the man said.
"No way would I give it to you." Jon said.
"Well, I thought you might say that. Luckily, I still have some magic." the man said, and Jon blacked out.
When Jon awoke, he saw the man holding the stone. "Give it back." Jon said.
"Not so fast. I challenge you for the stone." the man said.
"What?" Jon asked, confused by the statement.
"Well, according to the rules of magical items, I have to win it from you if you don't give it to me. And before you say no, I may not be able to use the stone, but you can't either if I hold it." the man said.
"Fine, I accept. Whats your challenge?" Jon asked.
"Excellent. First, the rules. Both of us have access to the magic in the stone, and winner gets it. Now, to make it more interesting...Whoever wins can do whatever they want with the other." the man said.
"What?" Jon asked.
"Well, whats the point of making a bet if theres no fun to be had." the man said.
"Fine, I accept. But just a question first." Jon said.
"Okay, what?" the man asked.
"Who are you?" Jon asked.
"I am..."
