You wake up in a dimly lit gray room with a large red button laying atop a pedestal in the middle of the room. You blink, and a man appears behind the button.
"Welcome! You have been selected to press the button of chaos. I will tell you what the button does, and you may decide whether to press it, or to leave it. Each thing that the button does will benefit you, but there will always be a drawback. When you press the button, what I say will happen, happens the moment you press it. When you have had enough, say so and I will release you back to your normal life, but the effects of the button will remain."
You feel a strange feeling inside of you, a feeling that says your soul has been bound to the button.
"So, the first one is, if you press the button, you will grow large wings strong enough to carry your weight, but you will have to feel the pain of them slowly ripping through your skin for hours and hours and changing your skeleton and organs to suit your wings, and you won't know how to use them without intense practice."
