Thousands of years ago, StarSwirl the bearded and a young princess Luna tried to crack the secrets of dark magic, only for Equestria to be put in danger. Their adventure ended only in death and corruption, and the incident was wiped from history. Unfortunately, Twilight discovered a single remnant of this past, and recreated an experiment described within.

She awakens in a mysterious world, where all that waits you is death and insanity. Without a means to replicate the experiment, how far will she go to get home?

Meanwhile, Equestria finds itself stuck with two, new occupants, and has been opened up to a monster unlike any other it has ever encountered.
