Shining Armor and Cadence's spell reveals something completely unexpected as it expels Chrysalis and her changelings out of Canterlot: A secret kept from everypony for several years...

Now with a TV Tropes page! Warning: Will Contain spoilers.

In the aftermath of the ruined wedding of Shining Armor and Princess Cadance, Celestia and several others maintain a vigil at Canterlot General Hospital. AU.

A/N: I'm sure that someone has done something like this before, but I needed to get the scene out of my head. Please give feedback and let me know if I messed anything up!

When the aspects joined forces to obliterate their once brother, a small fragment of uncorrupted essence remained. Merely a fraction of a percent of what was once strong enough to destroy worlds, it is banished to give both Azeroth and their brother a second chance at life. In Equestria, in the body of a whelp, the ex-aspect Neltharion is truly awake for the first time in thousands of years, realizing just how far you can fall before hitting bottom, and how hard the climb back up will be.

Twilight has grown curious about Bluebloods relationship to the princesses sends her around Canterlot in search of answers. however she quickly discovers that Celestia does not want her finding the answers she seeks... only giving her more of a driving force to find out what's going on...

This story was started before Princess Candice was brought up... so if continuity changes and it does turn out that she's an alicorn, and that alicorns are more common than expected... oops, my bad... i came into this with the thought that Alicorns were rare creatures, so yeah...

Celestia and Luna were born as unassuming foals in troubled times. But already marked for greatness, the simple earth ponies stand to face a world set against them, full of danger, fear, and sadness. A world they will change forever.

A sweeping epic taking place before Equestria was made, where Celestia and Luna must rise from normal foals to become the Princesses we know them as, beset from all sides by monsters, other ponies, and even the forces that govern nature. Their tale is as tragic as it is triumphant.
