in Russian

Twilight Sparkle has lived a full life but now she's a 115-year-old pony lying on her deathbed and waiting to pass on. As her time draws near, she receives a visit from a mysterious mare who has come to seek out the answer to a simple curiosity.

Graveyards.

They are where the living pass on into the afterlife. Where the dead rest and find peace that will last them for all of eternity, and their living loved ones come to pay respect to them. But for Twilight, an Alicorn who has laid numerous ponies to rest, and has paid her respects to countless souls in the vastness of her lifespan, the graveyard is a lively place. For her, 'best friends forever' isn't just a saying, and the bonds of a true friendship don't end when life does...

Twilight Sparkle has had a crush on Princess Celestia for a very long time. When Celestia's own advice prompts her to confess her attraction, Twilight discovers a secret that Celestia has hidden for hundreds of years. With the fires of the sun itself separating them, can Twilight find a way for them to come together?

Now with a reading by Dr. Wolf!

Certain alicorns have no regard for the rules of space and time. An astral sub-dimension becomes a potent weapon in what appears to be a divine prank war. Shining Armor hits the sauce.

Written for this contest thinger.

Twilight was so excited to have been appointed to head an important diplomatic mission to the distant land of the alphyns, even more so that Cadance, Shining Armour and Spike were coming with her to provide support.

But the truculent Grand Prince Caldrast is less interested in negotiating than he is in advancing his tenebrous personal agenda. As she deals with the machinations of the Grand Prince, Twilight discovers some members of her family hide secrets of their own...

Late one night, Twilight receives a letter from an anonymous scientist to work on a top secret project with long-reaching implications. If they succeed, Equestria will be changed forever. But what if the mysterious benefactor has other plans in mind? Twilight has decisions to make: About morality and mortality, love and hate, friends and lovers.

Book two: The Ghost Of You

Nightmare Moon visits Twilight in the night, and things get biblical.

Tirek. Discord. The Changelings.

The ponies have faced all these threats, and triumphed, but things could have been handled better. Princess Celestia knows this better than most. She knows that to face threats even greater than Tirek, greater than Discord, the ponies need allies. They need friends to turn to when the chips are down and the mad gods and cruel tyrants are on the horizon

She and Princess Twilight Sparkle travel to the Griffon Kingdom to meet the Griffon King. They seek to negotiate a formal treaty, something more than a rudimentary "You stay in your yard, we'll stay in ours." If the Changelings invade, or Tirek is once more a threat, it will not only be the ponies standing against them, but the griffons as well. It's only logical, after all. The griffons and the ponies share a border. They share ideas. They share refugees and concepts and cultures. And there haven’t been any major hostilities since the Pony-Griffon War. That was almost a thousand years ago.

It is logical to enter an alliance, but politics aren’t always about logic. Sometimes they are about past crimes, mistakes, and tragedies. Sometimes, past grudges simply can't be let go.
