When Pinkie asks Twilight to make her a portal to another world for no apparent reason and goes through it, she finds herself in Ponyville, but not the Ponyville she knows. All of the ponies are freakish and stupid and girly and shallow, and there are no talented unicorns to reopen the portal for her. How will she get back to her Ponyville before she goes insane from all of the creepy ponies here?

This story is a sequel to Bride of Discord

Discord and Fluttershy are blessed with a daughter named Screwball, who is gifted with incredible power that attracts the attention of the Queen of the Changelings...as well as her son.
When disaster strikes that tears Screwball's family apart, it is up to her to bring it together again.

What if Discord had not been turned to stone by the Mane 6? What if he had escaped?
It is three years later and the Mane 6 have moved on with their lives, all except Fluttershy, who cannot get the draconequus out of her mind. The others are happy in their new and comfortable lives, until their enemy returns and will only relieve Equestria of his havoc in exchange for a bride.

This has been adapted into an audio series.

Twilight sure has come a long, long way. But what about The Great and Powerful Trixie? Doesn't she matter anymore? Trixie sure thinks so.

Filthy Rich lives up to his name. But he didn’t get rich and stay rich by wasting money on stuff he sees as unnecessary. So when his home accidentally burns down he doesn’t bother with a hotel, he simply asks a favour of the family his family have had a long standing business partnership with; the Apples.
So until the insurance is paid and the house rebuilt, Diamond Tiara and Apple Bloom are sharing a bedroom.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.
