[Complete! With TVTropes apparently!]
Also, apparently, an animated trailer.

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.

Sequel to Judge Luna!
Princess Celestia allows a radio show to broadcast court cases from the Noon Day Court. At the same time, her baliff Noble Cause has... caught her eye. Dusting off one's courting skills and ruling a nation with a gentle hoof at the same time certainly won't be easy.

A flip of a coin. A twist of fate.

Twilight Sparkle, younger sister of Princess Celestia's personal student, Shining Armor, grew up listening to her brother's bygone dreams of joining the elite of the elite: The Royal Guard.

Now, fresh out of the Academy, this young mare is ready to prove herself equal to the deeds of the great soldiers she read about as a filly. Too bad the princess she ends up protecting isn't Celestia.

Ever had one of those days where everything's just gone wrong, one problem after another?

Of course you have.

Ever had one of those days when you wake up to find you've accidentally switched places with your counterpart in a world where you and all your friends are stallions?

...No?

Maybe that's just Twilight, then.

But the Princess of Magic isn't going to let a little thing like being in the wrong universe ruin her day. She has a schedule - a checklist! - and it matches up with this Dusk Shine's perfectly. Apart from the names and the genders, everything seems to be a match, and Ponyville has seen much weirder things since she moved here.

Being stallions or mares shouldn't make her friends that different. What could possibly go wrong?

Sequel to Let the Silence Sing!
Big Macintosh is dating Princess Celestia, and now all of Equestria knows thanks to a certain foal photographer. Dating a Princess is hard, thanks to her demanding schedule and his work at Sweet Apple Acres. The two rarely speak to one another during their get-togethers, but the silence sings between them.

This story is a sequel to The Celestia Code

When the monsters created by the dark crystal engine escape their prison, it's up to Princess Twilight Sparkle to deal with them. She gets help and advice from Princess Luna, but things don't go as planned. In fact, when a pony who relies on logic and rationality tries to navigate the stormy seas of emotional entanglement while simultaneously saving Equestria from a horde of evil creatures intent on destroying everything they encounter, nothing goes as planned.

Goodreads Page
100% Approved by Twilight's Library!

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

After watching another majestic night, Twilight is told to make a wish because wishing on a star always grants wishes. She refuses. After all, it's only an old pony's tale. Climbing into bed, she has a strange dream, yet little does she know, dreams are the desires and wishes of the heart. Upon her waking, she may just find that the stars are rather lenient in their rules and methods.

New installments are on a weekly schedule. Updates most likely to take place on Friday/Saturday CT. Occasionally I may do a surprise Monday update as well. Until then! Ciao and enjoy!

Cutie Mark Crusaders Time Travelers, yay! ...Wait, what?

When older versions of Apple Bloom, Sweetie Belle, Scootaloo and Spike appear from the future, Twilight and her friends are in for the time of their lives. The Crusaders have gone back in time on a mission that may decide the fate of time itself! They are fearless, they are resourceful, they... completely messed up right from the start, huh?

Now it's a literal race against time to set things right, as powerful enemies from the future attempt to claim the past for themselves. So join the Elements of Harmony and the Crusaders of tomorrow in an epic story of danger, hope, despair, betrayal, revenge, love and swashbuckling high adventure!

Just remember the golden rule: Time travel doesn't make sense!

As the centuries pass, cutie marks come and go. Some are common: the healing cross, the basic compass rose, the courier bag. Others are extinct: no more mercenary companies, no more mercenary marks. A few are incredibly scarce, coming along once a generation or less: the mark for luck falls into that category. A number only manifest when the call for them arrives: train tracks didn't appear until it was railroading time. But for the most part, ponies take their mark with its associated talent and magic as a blessing in their lives -- no matter what that mark turns out to be. And they accept it as they accept themselves.

Luna, in her first truly open palace session dealing with the public, is about to meet the exception: Joyous Release, a pony who wants nothing more than to be rid of her mark forever -- and every bit of the talent which comes with it.

But marks are permanent...

(This story takes place shortly after A Total Eclipse Of The Fun.)

Twilight Sparkle thinks that Cheerilee would provide a very interesting partner... to talk to... about literature. Nothing else. Right?
