In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

Applejack and Matte Palette were best friends when they were younger. Like her, the poor colt doesn’t seem to have much in common with kids his own gender, so they formed an unlikely duo. The two were inseparable, right up until Applejack moved to live with the Orange side of her family, and the childhood friends fail to keep in touch.

But time passes, and Applejack returns to Ponyville. Her biggest hope is to pick up where she left off, and that includes her friendship with Matte Palette. Something seems different about him, though.

My name is Rachel. Or at least it was. A bad decision brought me to the brink of death. I was "rescued" from that fate by some self-appointed "Spirit of Chaos." Or maybe he really was the devil, I don't know. He promised me a second chance but didn't tell me it would be in the body of a cutesy pony in a world which makes no sense. Worse, I think I've been set up, and something bigger is going on ...

Luna discovers a lone member of the Royal Night Guard stationed beneath her private balcony. As a question becomes a conversation, as an evening becomes a week, and as an annoyance becomes a friendship, an unfortunate truth looms large in her mind: nothing is ever as it seems, neither in dreams nor reality.

Sunset Shimmer weathered the storm. She returned from the darkest depths, and now she has good friends. People like her.

If I haven't sunk too far myself… maybe she'll help me. Then I can help Sonata and Aria.

Please, Sunset.

A pair of sequels, of sorts, are posted here and here.

Starlight Glimmer is about to embark on a few little friendship lessons. Five to be exact. However she’s still a little murky on how to get all her friends to cooperate so things go as quickly and efficiently as possible. Luckily A surprise visit from another friend might solve Starlight’s problem.

An alternative take on Every Little Thing She Does and inspired by a conversation with Tired Old Man.

After her little magic trick at the Fall Formal, Sunset Shimmer is not having the best night, and it's about to get worse: Principal Celestia just found out that Sunset has been living in the school clock tower. Now she has nowhere to live, and who's going to take in a teenager with personal issues that include recent demonic possession? No one normal, obviously.

But... maybe someone with a mohawk, a house full of creepy masks, and blue eyes that seem to see more than words -- or rhymes-- can say.

Winner of the Writeoff Association's February WriteOff, "Look, I Can Explain."

Spike now harnesses the bloodstone scepter making him the ruler of all dragon kind. Of course he hands it off as part of an important lesson on friendship, right? Naw. He immediately goes mad with power.

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.
