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.

When deafness stole away her music, Octavia Melody became the greatest composer in Equestria. Her Tenth Symphony lies finished before her, the pinnacle of all her work, done against all odds at the very end of her life.

Yet the clock ticks, and she finds herself under the gaze of gods and devils. With only Discord's mocking aid, Octavia must journey through her past to save her very soul.

(AU-tagged because the quasi-godly figures such as Celestia, Tirek, and Discord occupy a pantheon with rules and limits instead of simply being protagonists and villains.)

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Sanctaphrax, the city of knowledge. Wherever there's a question, there you can find the answer.

For the right price.

Unlike most of the citizens of The Ivory Island, the Admiral doesn't concern herself with economics. Her wealth comes in knowledge and the never-ending struggle to pull the future into the present. As long as she has the bits to keep Algol's Shadow running and its crew fed, she dives, and Sanctaphrax pay is more than enough.

When a routine salvage job leads to a discovery that could change the way the world sees the sunken ruins of Equestria forever, she can't help but get a little excited. She can hear the future knocking, just another dive away. The very stars themselves might as well be in her grasp.

This story takes place in the world of Goldenwing's story Empty Horizons, but it can be read without context.

There’s no end to the monsters that lurk in the dark.

Ghosts, werewolves, mad scientists, cultists, mutants, zombies, vampires, aliens and more lie in wait in the dark corners of Equestria, terrorizing the night. But the most infamous and dangerous of them all is the legendary witch Twilight Sparkle, with a five hundred million bit bounty on her head.

Seeking fame and fortune, Rainbow Dash sets out to defeat the legendary witch and collect the massive reward. The one thing she wasn't counting on was Twilight being less evil than she expected.

More stories set in this AU can be found here.

The surface isn't safe anymore.

In the ruined depths of Canterlot, a team of brave salvagers discover six mares, long forgotten but miraculously preserved. Though these mares cannot remember what happened to their world, they possess powerful magic that hasn't been seen for centuries.

Now the Elements of Harmony are thrust headlong into a world beyond recognition. Twilight and her friends must dive into the sunken remains of history to determine what happened, but Equestria isn't the harmonious land it once was. Before they can focus wholly on the past, they may first have to survive the present.

It isn't going to be easy.

This story is a sequel to Empty Horizons

For the first time in a thousand years, the old magic has returned to Equestria.

The Elements of Harmony have been torn asunder by the careless Equestria they found themselves in just one month ago. Twilight Sparkle fled into the ocean, pleading for her friends not to follow her after only barely stopping the destructive rampage caused by The Other. Rainbow Dash and Applejack, with nothing but their knowledge of Twilight's nature and a crew of seasoned adventurers, leave Altalusia hoping to find their lost friend and bring her back. Meanwhile, Countess Rarity finds herself trapped among the machinations of Duke Titus, but perhaps she can yet use her new position for good.

But the new Equestria remains as treacherous as ever for six mares lost in time, and the sunken ruins of their old home still holds fresh and terrifying dangers. Mysteries a thousand years old demand solving, and even those born on the floating islands of the new Equestria may find themselves torn between two paths.

The world changed in the absence of Twilight Sparkle and her friends, and with their return it braces for change once more.

Audiobook updates Thursdays and Fridays!

This story is a sequel to Topper’s Pizza

(Not necessary to read Topper’s Pizza before this one. The first chapter of this story is a copy-paste of that one.)

Knead Top is the lone owner of his pizza parlor, Topper’s Pizza. It was originally his parents’ pizza place, but they gave it to him.

…in their will.

One night, Princess Luna visits this pizza shop. They enjoy a pizza. Then, the next week, she comes back. And then again. And then again…?

They end up friends. One of them wants it to be something more.

But first, Topple needs to learn to let go.

After a mirror portal field trip being conducted by Luna goes terribly wrong, Ocellus finds herself trapped in a strange palace far from home. That palace, once abandoned, is now infested with a hive of love-starved changelings intent on using her only way home as a means to invade her world.

Otherwise, Ocellus appears to be alone.

At first.

The story is inspired by, and a homage to, my favorite game of the last decade. However, this story is neither a crossover nor AU. This story is set after "The End of the End" (but before "The Last Problem"), and is purely a My Little Pony story. Warning: rudeness and intolerance are not allowed in the comments, but spoilers are. Exercise discretion. Remain polite and on-topic. And please enjoy the story!

Inspired by the heroics of the mysterious mare known as the Stable Dweller, Silver Storm, a guard of the town of Marefort, decides to go on a daring mission to rescue her captured brother. Of course things rarely go as planned and her attempts at heroism drags her into a tangled web of plots and conspiracies as warring factions vie for control over the last great city: Dise.
