It has been several years since Chrysalis’ defeat during the Canterlot invasion. Since then, the fortunes of her changelings and kingdom have rapidly declined. With mass starvation, ponies capturing more of her spies and love collectors every day, and her own powers diminished to the point of being a complete non-threat to her enemies, she fears that it may soon be over for both herself and her entire race.

As Chrysalis reminisces about past failures, a pony named Time Keeper crashes a large metal box into her bedchambers. He claims to not only be a time traveller but also to have accidentally killed Twilight Sparkle on the day she was supposed to go to Ponyville to defeat Nightmare Moon.

In an effort to avoid the prospect of the universe tearing itself apart at the seams from the ensuing paradox, Chrysalis agrees to go back in time and live out a facsimile of Twilight’s life herself, and if time allows, she'll work on her own little project: shaping the future more to her own liking.

Past Sins AU. What would happen if Nyx was found by some-pony other than Twilight Sparkle? Some-pony who did not have her best interests at heart-- like a certain Changeling Queen? Inspired by Glimpses, by Pen Stroke.

After losing her hive, Queen Chrysalis is forced to start another one. Luckily she has the help of a few loyal subjects who never accepted their fellow changelings new way of life. They must stay hidden from enemies, collect enough food to survive and rebuild their strength. Now the first brood has hatched and there is something very different about one of the larva.

Discord's the only creature in Equestria who can recognize the human for what he is -- not the long-lost Seventh Element that never actually existed and couldn't have existed before the human arrived, but a meta-reality warper, an entity far more powerful than Discord with the power to warp the minds of all around him and the very rules of magic to make sure that he's always the Big Hero. And the role the human's assigned to Discord is the Villain to beat down or kill.

Pre-reform Discord's fine with being the villain. But on his own terms. Not dancing on some alien interloper's puppet strings.

Without friendship, or even allies, Discord's going to have to find a way to defeat a creature who can alter fate itself and who can even mind-control him. Or he may just end up worse than dead.

Trigger warnings: Mind control (magically induced love, magically induced friendship, magically induced stupidity, Discord being Discord), noncon/dubcon (magically induced love, other forms of highly dubious consent), rape (female on male), violence/gore (mostly against Discord), literally everything in chapters 19-21, humans not being presented as unilaterally wonderful and superior to ponies and/or draconequui.

sequel to: Second Chances and the Cost of Life

Twilight lived and died a hero. Her body reanimate by Death itself to act as its reaper. But Death cannot grant life, and she fell in a way worse than before. She became a monster, but was stopped by her own friends.

She slept once again, but Death needs her. So it makes deals, stretches the rules, just to get her to live once again. But living again is difficult, particularly when Light itself remakes you.

Twilight has a new life, and a duty that must be done. The only question;

Will she manage to live a new life, instead of her old one? It's going to be hard. Time to see.

This story is a sequel to Path of Kindness and Blood

This story is a sequel to Hopes and Follies

The fallout begins across Equestria as Trixie and Discord's actions become more widespread, forcing a response from the princesses.

Trixie works her way towards Las Pegasus, torn between her desires to be with Twilight and her fears of what their next encounter will truly involve. Does Twilight truly want more, or was she caught up in the spur of the moment?

Fluttershy's changes have forced Discord to try to hunt her down before the princesses do. Yet the former pegasus is lost between rational thought and primal instinct, creating terror across Equestria.

Somehow, Twilight needs to balance between her interest in the newest Alicorn, and her duty to her fellow princesses. To Equestria.

Amidst the myriad of hopes and follies that make up one's actions, can there truly be a happy ending for everyone?

Only one way to find out.

This story is a sequel to House that Heartbreak Rebuilt

Heartbreak, after a roller-coaster ride of an adventure, is finally in a home of her own, and an honorary Cutie Mark Crusader to boot! Unfortunately, her time with the Crusaders and the Summer Readers Club is more than just social calls - it's also a one-of-a-kind opportunity for Equestrian germs.

It's Fluttershy's turn to teach Heartbreak a lesson in friendship, but it will be a struggle to get a real understanding of kindness through to the sickest, most stubborn tan mare in Equestria.
