Bioshock meets MLP in this psychological thriller, where Celestia's new faithful student, Siren Song, must discover the truth behind the city beneath the waves.

Beautiful, gifted, and faithful student of the Princess of the Sun, Siren Song has very nearly everything a pony could want. Sometimes though, in the twilight hours, Siren can see the sadness in her mentor's eyes. Once, ponies whisper, the Princess had another student named Twilight Sparkle, but she left Equestria, never to return. The pony who has a perfect life just needs one more thing—to convince Twilight Sparkle to come home so the Princess will smile again. But when Siren arrives in pursuit of Twilight, she soon finds herself trapped in a city of horrors, with only its monstrous denizens for help.

After the Changeling invasion, Celestia and Luna make the decision to have Twilight investigate the Elements of Harmony and solve the mystery of their power.

A thousand years later, Rainbow Dash awakens in a world she does not recognize. She has no idea how or why she came to be there.

She soon finds allies in Star Fall, a scholarly pegasus whose Talent is Magic, and Astrid, Star Fall's Griffin guardian. Together they set out to discover why Dash has been sent to the future, and how she might return to when she belongs.
