Kain got back to his reality and his room had changed back to suiting him as a him. Kain was pleased.
Kain returned to the Genie. Selecting a slightly improved version of his original body as his new form. "Genie, I need your help."
"Master?"
"Well, I have a way to change myself into whatever I want, even after you leave... now I'd like a way to change other things, a magic ring or an amulet would do. I'm not sure how to word the wish to be able to allow me to change anything... while not being able to ever enslave your kind ever again."
"What do you mean change anything?"
"Objects is one example, a car when I need it, money or things I want. History is the big one though, I'm getting a new life and memories when I use the lamp to change my body, and surely one of those times I'd find something about that life disagreeable. I may want to go out and have fun as a 22 year old but after using the lamp to change my body find myself in a world where I got someone pregnant at 18, needing to stay home and parent. Through no fault of your own of course. Or I have grown up, started a family, and wanted to make a minor change to my body, but upon return, one of my children doesn't exist."
"I see, You desire a magic object, that will bring into existence a new reality of the user's choosing, when and how the user decides to utilize that ability, but cannot be used to enslave genie kind."
"Yes, it seems we are at an understanding, that is my wish along with the magic on the lamp only changing what is relevant about reality unless desired by the user. That should be better right?"
Kain returned to find a small band on his finger. He concentrated on imagining the layout of the house, expanding it and rearranging the space. When he opened his eyes his room had tripled in size and there is a fully furnished third floor as a giant open space filled with a TV/movie/console area, computer, pool and air hockey tables, as well as art items like a drum set and painting area. There are slides to get back down to the 1st and 2nd floors, and the house now has an elevator to get up there as well as a dumb waiter connection to the kitchen.
Kain again rubbed the lamp, not changing himself, "Genie, I am pleased with how you granted my second wish. It's time for my third. As I am sure you have seen happen before, I now have 2 of the most precious items in the solar system, possibly this universe and need to protect them. I wish the items were bound to their owner and could be lent for use while ownership is retained, they could be summoned by their owner, and only used with their owners permission. Also, I ask that you would never seek revenge against humanity for the terrible things it did to you, and I wish that you had the option to return to your original dimension at the time you were pulled into ours. I don't know how Genie family and friends work, but I know that here, its the most important thing. Go and be free."
"Granted"
Kain took the ring off and tossed it into the void that this room was, and desired for the ring to return to his hand, and it did. Kain looked at the Genie and smiled kindly.
"Genie, you have successfully and completely granted all my wishes as I intended them to be. T..."
The genie was gone. Kain was expelled from the lamp and now owns very powerful relics.
