Chrysalis, the last Queen of the changelings, is dying. With her death, her children will die, and the changelings will cease. She has one final plan, a coup to save her race, her children. She must make a new Queen, one strong enough, and smart enough, to save her people. It will be her legacy, and her greatest achievement. Too bad she never asked Twilight if she wanted to help

It's just another day in Eureka, and that means yet another piece of technology to be tested. This particular prototype is being tested to see if it can create any living creature. Guess who the newly arrived in Eureka is.

Despite the slight oddity of a talking pony, it's not much out of the ordinary. Hopefully, it stays that way.

Right before the big Canterlot Wedding, Twilight Sparkle makes a 'false' accusation against 'Princess Cadence.' Abandoned by her friends, teacher, and brother, the heartbroken pony experiences conflicting feelings of guilt and anger. Seizing this opportunity, Chrysalis takes in the fragile unicorn as her protege for her plan to plunge Equestria in darkness and chaos. With the Elements useless and the world being torn apart, how can Princess Celestia and the Elements possibly undo the damage they could've so easily prevented? And will Twilight be able to push away the darkness, or lose herself to it?

Note: Alternate Universe because of a few....'secrets' certain characters have, as well as obvious other reasons.

A few weeks ago, Chrysalis and her brood attacked Ponyville for revenge against Twilight. During the fight, the final spells of the two collide and create a portal that they're sucked into. The Princesses with the help of the others manage to summon them back only to find... that the two are marefriends!? How the buck did that happen!?

Princess Luna's Lunar Stallions kidnap Twilight Sparkle when they see how lonely Luna is, and give her to the Princess as a gift. Nightmare Moon emerges from Princess Luna's psyche during the sleepover. The dark goddess would love nothing more than to have the beautiful mare all to herself, and the resulting chaos forces Celestia to call a psychologist to sort out Luna's multiple personalities.

Twilight likes logic. Logic makes sense. And it's those very things that make sense that Twilight does so enjoy.

A story about Twilight as a filly, set after she witnesses Celestia raising the sun and becomes inspired to study magic. She possesses great capacity for educated assumption, with which her natural naivety does not well mix.

It's been a hard day of study, and Twilight needs to rest for her upcoming test. However, not everything will go as expected when a certain mosquito barges into her room. What will Twilight do?

Twilight Sparkle goes on another rampage when Cutie Mark Crusaders ask her a mathematical riddle she can't solve. As usual, it's up to her friends to try to stop her before her magic frenzy causes serious damage.
But... among her friends, is there anypony more skilled at math who could hope to solve a riddle even Twilight has trouble with?

Brotip: try to help Twilight with the riddle yourself as you read. :D

Your body is not ready.
