Two hundred years ago, Luna disappeared, and a few hours later, so did Celestia.

A great supernatural threat has forced Celestia and Luna to leave Equestria behind. Now Celestia wanders the universe, encountering its many strange creatures, doing good where she can, and searching for her sister.

A collection of short stories exploring themes in the psychology and philosophy of human sexuality, but with horses instead of humans. Each story focuses on a different pony.

Four young male adults in Manehattan navigate sexuality, romance, work, academia, and the magic of friendship.
Smut note: this story contains discussion of sex and some vulgar language, but no detailed depictions of sex.

One day, Applejack and Big McIntosh are alone in an orchard when Big Mac laments the problems of his love life. Then the conversation takes an odd turn, with big consequences for AJ and Big Mac's relationship.
Pinkie is ravenous, but circumstances forbid her from eating anything in Sugarcube Corner.
