But when something goes wrong with casting, Twilight finds herself turned into a Draconequus and unable to control her new chaos magic.

Prince Antares, formerly the human TD Powell, has ascended to rule Equestria alongside Celestia and Luna to form the Equestrian Triumvirate. Taking his residency in Baltimare, Antares comes into his role as smoothly as he can, given the circumstances.

But not all is right with the world.

A warmongering king in the newly formed minotaur nation has just allied with the griffin empire, a country that recently gained a leader unfriendly to Equestria. Now Antares will face his first true test as an alicorn prince of Equestria. He must lead his peace loving ponies into the hells of war, and face an Equestria that will never be the same.

This story is a sequel to Winds of Change

Changelings have always been a secretive race, shrouded in mystery and keeping to themselves, staying unnoticed and in the shadows, feeding where they could and avoiding discovery at all costs. When Chrysalis made peace with Celestia, the veil of secrecy and subterfuge was shattered, and thanks to Twilight's efforts, the other changeling queens can no longer remain hidden.

Of course, Twilight is more than happy to leave the tricky diplomacy to Celestia. She's having a hard enough time dealing with her own amorous changeling queen and her new personal pegasus guard competing with her.

Also, there are sky-pirates!

A few extra, slice-o-life chapters are here: On the Rocks

Nobody has seen the Sirens since the Battle of the Bands, and nearly everyone is fine with that. Months later, Sunset Shimmer feels her entire life is going better then it ever was since the Fall Formal. She has her best friends, the school no longer hates her, and it's summer vacation.

One night on her way back home from band practice, she finds the three powerless Sirens who are now homeless. Deciding to be a nice person, she takes them in, but the question becomes how long will they stay? And what will happen to them in the future?

After transferring to Canterlot High, Twilight Sparkle realizes she has a crush on Sunset Shimmer. Being the analytical type, she develops a plan to capture Sunset's heart...using the scientific method.

Sex tag for mild sexual references.

[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.
