There are many secrets that Celestia would prefer nopony ever know...

When Celestia asks for a moment of your time, you say yes.

Twilight Sparkle comes upon a startling discovery. No matter how hard she tries, she can't curse! Scientific observation must commence!

The end is near, nearly all of humanity has been converted and now the survivors are mounting a final attack on Equestria.

When Rarity’s friends discover that she has been secretly meeting with an escort, they begin investigating, and soon discover a web of lies and unrequited romances none of them ever could have expected.

Princess Changeling Rainbow Magic Pants, the beloved being from beyond Eqestria's skies who also resides in a land flooded with magic much as if Starswirl the Bearded's basement was flooded, senses that Twilight Sparkle needs her help.

Fluttershy, with the help of Twilight, plans to tell her friends that she's a changeling, but when Fluttershy and Twilight are teleported to a mysterious forest, it seems the two won't be able to find their way home.

When a little filly gets bored with thoughts of grandeur, she schemes. When she schemes, she recruits. When she recruits, she and her brother do the only reasonable thing they can think of. Try to take over Equestria, one princess at a time.

Celestia decides to attempt to reform Discord, so she taps a pony with a similar background for the job. ("Keep Calm and Flutter On" as it occurs in the Petriculture AU.)

Now in the employ of Princess Celestia, Project 64 must come to terms with his new life and what it will bring, but how will he do that with the visions and memories of the past coming to haunt him at every corner? What new enemies will he face?
