Lotus Blossom's twin, Aloe, isn't exactly as similar as everypony would guess. In fact, the earth pony has a rather large secret that HE doubts very much everypony would react favorably to. However, when he starts having trouble properly focusing around one of the hoofful of ponies who know his secret, he starts to worry he may be falling head over hooves. If he pursues her, will his secret be able to hold, or will he have to abandon it to get what he truly wants? Not to mention, can a pony who's so rough and tumble work with one who bruises so easily?

This story is a sequel to Dexter's Lab: Equestria

He was so sure Nightmare Moon wasn't real. He was so sure all the stories about Nightmare Moon were merely fabrications meant to induce fear in the ponies of Equestria, and insure their loyalty to the alicorns upon the throne. In fact, he was so sure Nightmare Moon didn't exist, he built a time machine to go back 1000 years and prove it.

Needless to say, this time-travelling colt genius bit off more than he could chew.

Now the 8-yr-old must survive the chaos of Nightmare Moon's uprising, forging unexpected alliances while learning to trust in the word of others. But unfortunately for him, Nightmare Moon isn't the only surprise in store for this colt.

Twilight Sparkle has been called to Canterlot on royal business: a university's archeology department needs help with a tricky project. All very routine and hum-drum for her... but for Rainbow Dash, it's a chance to get an inside view of the exciting and fast-paced world of ancient history! But how much does she really know about the field? A chance meeting with a larger-than-life pony teaches her about the difference between reality and imagination.

On a dark night filled with even darker magics, an insane cult attempts to give Nightmare Moon a body and life of her own, utterly separate from Princess Luna. But, when the spell is interrupted by Celestia, something unexpected is created.

Now, a little black alicorn filly named Nyx finds herself living under the care of Twilight Sparkle, only to be haunted by memories and emotions from her past. Is she Nightmare Moon reborn or is she simply a doppelganger with a soul and mind of her own? Can Twilight Sparkle protect Nyx from those who refuse to see past her dragon eyes and black coat?

Or, will Nyx be forced to inherit the sins that may not even be hers and become the greatest evil Equestria has ever known?

(This story occurs after the events of "Biased and Incomplete")

Rainbow Dash was astonished when she encountered the real life Derring-Do that inspired her favorite string of novels, but was crushed to learn that her hero wasn't what she expected at all. The two parted ways in anger, but Dash hasn't given up on her completely: When an opportunity arises to heal the professor's crippled wing, Dash and Derring go on a real life adventure... but adventures have a way of spiraling out of control. The bookish archeologist knows nothing about swinging from vines and swiping ancient idols (and she prefers it that way), but an unbreakable curse of death forces her to dive right into a frantic race for the greatest discovery of all time: the secret to immortality itself.

Whether she believes it or not, Derring-Do has only a few short weeks left to live. But with the incomparable Rainbow Dash by her side, that's more than enough time to save the world.
