Twilight Sparkle has kept detailed notes on her magical ability for her entire life. Nopony's terribly surprised. After becoming the Element of Magic, an alicorn, and the Princess of Friendship, her abilities have changed dramatically. Again, nopony's surprised.

Twilight Sparkle is going to live forever. She won't be alone. The Elements of Harmony can never be separated by something as banal as time.

That surprises a few ponies. That surprises them a lot.

Twilight Sparkle will not outlive her friends, but Twilight will live forever. Faced with the harsh reality of being an alicorn Twilight has made a decision that will affect her friend’s lives forever.

The Mane Six have become alicorns! While studying new alicorn spells, Twilight finds an old book from Celestia with a new spell. Under warning by Spike, Twilight sends the mane six, Sweetie Belle, Apple Bloom, Scootaloo, Spitfire, Derpy, Lyra, Bon Bon, Vinyl, Octavia and Rose into a strange world. There, they meet a human named Walt Disney, and he tells them what happened.

Many years ago, Walt traveled to Equestria and spent time with Celestia and Luna. With the princesses, they created a joke spell that sends the spell caster and close friends into his magical Disney world. Now as Disney princesses, they must survive both their fairy tale and Pinkie's blabbering!

Thanks, man!

Alicorns are immortal. Earth ponies, unicorns, and pegasi are not.

Princess Twilight Sparkle has no intention of going through life without her dearest friends...

Even if she has to do something extremely questionable to make that happen.

This story is a sequel to A Tale of the Sun, Moon, and Stars

It has been almost a century since Twilight and her friends had discovered their destiny, and Celestia has been wracked with constant regret over the fate she has condemned her friends to. Now Luna looks to those very ponies to help Celestia smile again.

Celestia's story, and a sequel to A Tale of the Sun, Moon, and Stars.

The Mane Six had just arrived at Twilight Sparkle's Castle for a four night sleepover.
And when they decide to help Twilight bring the remaining books that survived the battle with Tirek, they discover a book with an odd title..... So Twilight Sparkle decides to read it out loud, and everything seems fine, untill the next morning..... That is.....

Due to an editing/publishing error, all of Twilight's friends have now 'officially' died of old age. This leaves an immortal Twilight to grieve over the tragedy of how she outlived all of her friends and will continue to do so for the rest of her eternal life.

Seeing the obvious pain that this news is having on Twilight, Princess Celestia moves to console her with the help of her supposedly-but-actually-not-really-deceased friends.
