For years, Twilight Sparkle and Queen Chrysalis have been at each other's throats. Both have experienced victory over the other, and both have experienced defeat. Out of all the creatures in Equestria, none despise each other the way the pony Princess and changeling Queen do. They seemed destined to remain locked in battle forever, or at least until one is finally dead at the hooves of the other. The cruel insults, the vicious loathing, and the powerful spells that have passed back and forth between them at each meeting have become the stuff of legend.

Imagine Twilight's surprise when she finds out changelings consider this dating.

And now they're married.

Sequel: Pony Courtship Rituals

Some beautiful fanart of the end of chapter three was done by Dmann892; you can see it here.

More awesome fanart, this time from chapter one.

Now with a TvTropes page (obligatory TvTropes warning goes here).

If you want a Russian translation, you can find it here.

There is now a reading of the story on Youtube, which starts here.

This story is a sequel to Changeling Courtship Rituals

Queen Chrysalis attacked Canterlot, brainwashed Twilight Sparkle's brother, kidnapped her former foalsitter, defeated her mentor in combat, and conquered her kingdom. She kidnapped the sisters of Twilight's friends, turned them against one another, and tried to drain all of Twilight's magic. Queen Chrysalis has, at every opportunity, done her very best to utterly destroy Twilight Sparkle's life.

For some reason, this has not caused the pony to fall in love with her.

However, due to Twilight's misunderstanding of changeling customs, it does mean they are now married. Twilight eventually managed to tell the Queen the truth, but she forgot that whether it's a kingdom or a heart, changelings conquer.

And since the changeling way of conquest didn't work, Chrysalis is determined to try the pony way. The only problem is, of course, she has no idea what that is. But she knows someone who does: Princess Cadance.

Now, with the absolutely sincere help of her mortal enemy, the pony she once locked in the caves beneath Canterlot while trying to steal her husband on their very wedding day, Queen Chrysalis is going to woo the sister-in-law of that very pony.

Surely this is the most perfect plan ever devised.

Takes place roughly after season five (so Starlight Glimmer is running around occasionally)

Rainbow Dash is the perfect girlfriend.

Sunset breaks up with her anyway.

Patreon. Ko-fi. Picture of me looking handsome.

When five foals asked Princess Twilight Sparkle to please try and paint the moon purple during Nightmare Night, she initially refused. It wasn't until they insisted (and Princess Luna quite basically dared her) that she relented. She only relented, however, because she really thought she wouldn't be able to do it.

Too bad she thought wrong.

A very silly story that started as a prompt that got way, way, way out of hand.

Her expedition failed, Twilight is trapped in the world of the breezies, unable to tell when, or where the portal will re-open.

In the meantime, she must do her best to survive, to find a clan, and of course-

STUDY. EVERYTHING.

Cover was drawn by Kaleido

Starlight Glimmer has gone back in time. Each time Twilight tries to stop Starlight, she fails and is flung back through the portal and into a broken, twisted Equestria, ravaged by wars or monsters, each version worse than the one before, barreling toward the destruction of the world. Until she lands in a version of Equestria that ... isn't worse. It seems unchanged, happy, normal. The only real difference she can find on the cutie map is that her castle isn't there ...

... but the library still is.

Canterlot is in ruins, Celestia is an out-of-control god flying west, and it's up to Twilight Sparkle and her friends to save Equestria.

Strongly Recommended Stories:
The Brightest and the Best by Pineta - The events in this story are considered to be completely canon to this timeline and explain Twilight's entrance exam to Celestia's School for Gifted Unicorns. I cannot recommend this story enough.
MLP Annual 2013 - "The Fall of Sunset Shimmer" - As above, the 8-page short comic in the beginning of the Annual is also considered to be canon, though with some major variations.

Version 3.0 Edit: Extensive grammatical and mechanics changes. Adjustment to timeline of Sunset's second mirror experience.

Twilight Sparkle and Sunset Shimmer have a leisurely talk on the couch about their day.

Historians will look back on it as the most important–and dangerous–event across two universes.

An "official" "entry" into Oroboro's SUPER SUNSET SHIPPERS MELEEEEEEEEEEEEEEEEEEEEE.

Twilight Sparkle never knew just how much she wanted to adventure with her mentor. Until one day, that adventure is thrust upon her. Now, she can't wait for it to be over.

Like any seasoned adventurer, Princess Celestia forms a party of capable, credible threats. Shining Armor as the handsome tank, a damage sponge like no other. There is a grey vizard to do all of the morally objectionable stuff that Princess Celestia would never sully her hooves with. With the aid of Twilight's snark, Princess Celestia leads the way to recover Moon Rose, a foalnapped filly.

Together, they face the Fortress of Egress.
