Fate, something that seems destined to happen. There's no time or way else it could happen but at this precise moment and precise way. No possible way of changing it, it can't be forced, and it most definitely is not in your hands.
Chance, something that comes up unexpectedly You were in the right place and the right time, otherwise it would not have happened. Chance is fair, chance is an endless amount of possible for our present and future, chance is ever changing, chance is unpredictable.
But what if chance became predictable, what if fate was in your hands, what if all the rules were changed.
