You were told about this oracle who could send people to the past, and you decide to check it out. You reach into a closed store and check the place out, only to find a small shining orb. Curiosity takes over and you touch it. Within seconds, you black out.

You walk up and take a peek, noticing a woman with black hair seeming to talk to.... Two small black figures, one hugging the other. You...?
