Start Over: Each time you make your pact you must decide whether to accept or decline a special offer by Praeter. If you accept he will turn back time for your body and soul if you should die while bound. The exact time of the binding on the next day you awake with no memory of your time bound, but in the exact same shape directly before the binding. Anything taken from you is still gone, but physically and mentally you are exactly the same. However, upon awakening you must complete the ritual again and he automatically gains full control over you.
Define "full control"? Does it mean you suffer his influence no matter what? Does it mean you are an NPC now?
Also, I like it. Pact Magic always needs more lovin'.
All that I say applies only to myself. You author your own actions and choices. I cannot and will not be responsible for you, nor are you for me, regardless of situation or circumstance.
