One night, an amazing display lit up the sky over Ponyville. A comet, brighter than any in living memory, was making its way through the sea of stars. The residents of the town gathered en masse to witness the spectacle. As was the tradition for such an occasion, many ponies made a wish on the celestial body, hoping that maybe, just maybe, some of them might come true...

Twilight and her five friends are transported during a botched spell, across dimensions to... Ponyville, Equestria? But not the same one that they knew. Sitting on a bench is Harpsy and Babar. The Doctoress avoids apples from an aspiring Applebuck. And in a library across town, six stallions join their forces as they try to decipher the appearance of filly look-alikes of themselves around Ponyville!

Twilight Sparkle wakes up on the streets of Manehatten with no idea how she got there. Things take a turn for the strange when a scroll appears in front of her, threatening erasure and signed by "The Reapers". Just what is this game that Twilight has gotten herself into, and can she survive for seven days?

The star system Omega Centauri was just another oddity on a map to scientists in the not too distant future. However when they found the star was orbiting an earth-sized, earth-like planet instead of a black hole as its motion had suggested, a mission was scrambled to investigate this most unusual of celestial behaviors.

Hamstrung by politics, and nearly crippled before it began, the 'Lone Ranger' mission was reduced to just one crew member and left to his own devices.

These are the logs of Arrow 18 and its lone commander. This information is classified TOP SECRET by the Global Space Agency.

Do NOT tell the princess.

Luna has had enough of Celestia's games, and has found the perfect means of revenge. Using a long-forbidden spell, she transforms her sister into little more than a small filly, all so she could pull the greatest prank ever. Unfortunately, she soon learns that before you fool around with dangerous magic, you really need to read the fine print...

A sequel can be found here.

In the many years after the Conversion Bureaus' shutdown, Twilight Sparkle is tasked by the Princesses with finding the last living human on Earth, Isaac Hamilton, and learning the story of his past. What she hears is a tale of loss, tragedy, joy, and the discovery of one's place in the world. But how much longer would that place last with what Twilight has to tell him?
