alright fine

you wave your hand and set the new rules in place. the new world all set to go you decide to shift your attention to your living situation. you didn't mind living with your parents but you also wanted independence. you wonder if you can make extra dimensional spaces. you wave your hand and a door way comes into existence. you close your eyes and concentrate, furnishing the space to your exact liking. you then set up a two way link so you could transport yourself and anyone you want there anytime you want.
