you are 11 years old. you live with your parents in Rapture an underwater city built by businessman Andrew Ryan which was meant a haven for scientists and artists to use their talents to the fullest and not be held back by Society.

he is a true believer in objectivism the belief that opportunity to use reason without the initiation of force is necessary to achieve moral values, each individual has an inalienable moral right to act as his judgment directs and to keep the product of his effort. scientists in Rapture found a substance dubbed Adam in sea slugs that can give the user unnatural powers. to get more of this drug they started conditioning kids to gather the Adam. with spliced-up men wearing diving suits as protectors, they named Big Daddy.

you are the last child not to be conditioned. every other child is going around with their big daddy gathering Adam from corpses you hide around hoping not to be caught and turned into one of those little Frankenstein. right now you are wandering around for Frolic for food. when a creature appears. it looked like a big daddy but with a more feminine physique. Its diving suit looks a little different than usual. they looked taller and much more thin. their helmet had a large sphere with two portholes, it turns it had while looking at you.
