Princess Celestia’s School for Gifted Unicorns is famous across Equestria as a center of academic excellence. Only the best and brightest unicorns are offered places, selected by their academic merit, magical ability and passion for study. To make the admissions process as fair and reliable as possible, all candidates are given three exams by different teams of examiners, who then meet in private to decide which students are most deserving of a place.

This story is a sequel to Vanilla Twilight

Rainbow Dash has a problem.

She might be in love with Twilight Sparkle and has yet to admit it to anypony, least of all Twilight herself. After the events of Vanilla Twilight, the two have grown much closer together, spending more time together and sharing their interests. Unfortunately for Dash, Twilight hasn't caught on to her feelings yet, and she could be content with just letting things progress as they are...

If only she hadn't sent that blasted letter admitting it.

Now, thanks to a pair of meddling princesses, Rainbow Dash finds herself on a globe-trotting journey with the subject of her affections. On the surface, it might just seem like a simple task for the Princess, but for Rainbow Dash, it might be the very thing that forces her to come clean with her feelings, or forever face her doubts. For her, in the world of life and love, sometimes it's best to take it one dream and disaster at a time.

This story is a sequel to The Cloudsdale Report

  Twilight’s got her nose stuck in a book. Sunset wants to go see the rest of their friends.

  Things snowball from there.

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.

Heavy is the head that bears the crown. Light is the heart that shares its burdens.

Historian’s Note: The Tarnished Crown occurs three weeks before the events in the Season 4 Finale, Twilight’s Kingdom.

Version: 2.3

Celestia and Discord, as teens, flee their destroyed homeworld to a new world promised by a letter from Luna. But Discord can't escape his nature, nor Celestia her memories. Being a chaos mage on a starliner is a death sentence, and yet, Discord has to keep using his mind-control powers to take Celestia's emotions away, at her request, because otherwise she wants to die. And Gray Celestia, the discorded Celestia with no emotions but the drive to protect herself and Discord, will do anything that needs to be done to save them both.

Warnings: suicidal ideation, consensual mind control that's still kind of messed up, genocide, a near-execution, mass murder, and comforting lies.

Cover art is by ponkamena/polkahorse, who now goes by ashiida (link goes to their new deviantart account). The source link goes to the derpibooru version. This was the closest I could get from all of derpibooru, though in the fic they're both much younger than the art would suggest.

Rainbow Dash flies east.
