Now with a Russian Translation by NovemberDragon | [ponyfiction.org] [tabun.everypony.ru]

The three-creature crew of the Peony, a mining and haulage ship running routes in the distant Reaches, finds a distress beacon emanating from a derelict ship. But what they find, thousands of light-years into deep space, might have been better left adrift.

When they began to read the ancient book Twilight and Spike only had the slightest of ideas what it could possibly be about. As the illuminated inks revealed to them an image of Princess Celestia locked in combat with a massive dragon and his sons they realized that the song written upon the aged pages was telling of a long forgotten battle...

... and that the Celestia they know and love is capable of things they dare not imagine.

Inspired by the image "By Celestia's Might" by John Joseco.

A mammoth being of ancient metals and gears has awakened from the earth with the sole intention of destroying every villain in Equestria. Untouchable, unmovable, Discord remains as its last target of worth. Now the Spirit of Chaos must beg for Celestia's aid, even if things are so much more complicated than he would have ever wanted.

For as long as any of the Cutie Mark Crusaders can remember, Diamond Tiara had always been the biggest bully they knew. But when that said bully dies in an accident, each of them starts to go through their own emotional experience from this sudden change in their lives. Each will learn more about themselves and about the pony who they all thought they knew before she is laid to rest.

***Takes place just after season 3 but before season 4. This story is completed.***

Twilight Sparkle has always been frustrated with Discord. His ability to do anything, with no more effort than a snap of his claw. It shouldn't be possible. His power had to come from somewhere.
Then, one day, Twilight lets slip how she feels. Surprisingly Discord agrees to explain it to her. To give her the secret to all of his powers. If she's willing to pay the price that knowing it all will bring.

Daring Do cannot believe her luck when she is asked to help explore the most ancient tomb known to ponykind. But terrible danger awaits her, for beneath the earth rests something beyond equine understanding.

After an expedition into the Everfree Forest ends in disaster, Applejack and Rainbow Dash take refuge in an abandoned cabin until morning.

This is probably a poor decision, but it's only one night, after all. How bad could it be?
