If you were the Creator

Okay, I do this when I am bored or can't go to sleep. What if you had the power to enter any book you wanted to and control the events in that book? I used to do with Stephen King's IT but have recently been going into Randland. What would you change? Who would you talk to? Remember, you can control everything just as if you were the Creator. So weaves won't touch you, you know the outcomes, ect...
