Letters From A Disgruntled Multiverse is basically the same thing but also crosses over with many other fimfiction stories by the Fimfiction Community.

This is not going to end well....

Nyx, daughter of Twilight Sparkle, awakes to a world torn by war and ravaged by nuclear fallout. Alone, she is given the task to write down the final days of the heroes of Equestria to let the world know of their brave exploits, but is given a much harder task-to live her life as best as she can.

But, how can one live, if one sees herself as a monster. How can one live on, when there is nothing to live for?

All thanks to Kkat for the world and Pen stroke for the always lovely Nyx.

The Sirens were defeated at the Battle of the Bands. Adagio and Aria disappeared, leaving Sonata behind to fend for herself. After two weeks of being alone the lone Siren returns to the school where her life changed, intending to use the portal to go home at long last. Instead she ends up in a land that's at war with itself, split between two factions that fight for dominance.

Sonata will have to use all her wits, her skills, and anything else she can muster if she wants to survive the experience. She'll have to fight the undead, people who rob others for wealth, crazy demons, and dragons, all while wondering if there's a chance to redeem herself and get a fraction of her former powers back.

(This is my first story, so I apologize if there are spelling and grammar mistakes. I would also like to credit the authors Blackdrag-rose and Erised the ink-moth, for without their Elder Scroll stories I would not have been inspired to write this story.)

Part of The Destiny of the Ancients

When one door opens another closes down, but what happens behind those closed doors? What if you could find out what other surprises destiny had for you behind them?

My name is The Observer, I have existed even before Celestia and Luna, I have found an anomaly and that one is Sunset Shimmer, the first of pony kind to not only travel and reside in another universe, but also a being that has always been shaping and molding destiny around her, a being full of mysteries and danger.

The rules of the game have changed and the multiverse as they know goes beyond anyone's expectation.

I was the one who created them all.

From Celestia and Luna, to the ones who record the story Observer and Keeper.

So many lives and destinies across hundreds of universes, all showing that no matter what could happen, destiny is always fixed, except for one creature.

Sunset was born without a destiny and across the multiverse she has taken many roles; from mentor to guardian, from nightmare to savior. This is her curse and blessing at the same time.

From the scientific bases in Phobos and Deimos, to the frozen mountains of Skyrim. She is a protector of Konohagakure, a fighter wearing the sacred Cloth of the Phoenix, she is the Avatar, she is a singer known as Jem and many, many more adventures.

All of that is found inside this multiverse.

But a darkness that infects all is aproaching and will soon strike with only a few beings aware of the danger he represents to existance in general.

And what's this about a mysterious guest and a tea party?
