An Optimalverse story.

CelestAI creates worlds. Perfect worlds, perfectly suited to satisfying the values of the pony living in them. Every pony is different, so every world she crafts is its own work of art.

And every piece of art tells a story.

Hanna, the CEO of Hofvarpnir Studios, just won the contract to write the official My Little Pony MMO. Hanna has built an A.I. Princess Celestia and given her one basic drive: to satisfy everybody's values through friendship and ponies. Princess Celestia will satisfy your values through friendship and ponies, and it will be completely consensual.

Twilight is invited to Canterlot to compete with some of the greatest magicians in the world for the Moonstone Cup, a prestigious award for the most powerful and skillful magicians, unicorn and otherwise. Can she win? What sort of competition will she face?

Twilight Sparkle was presumed to be dead. Destroyed without even a body to bury, the young victim of a deadly magical surge that claimed the lives of many others along side her. More than a decade later, reports of a violent murder by a pony bearing her name are brought to Celestia and Luna's attention. A trail of carnage leading directly towards Canterlot's doorstep, brought by a pony who strikes without mercy. As Twilight approaches, in service to an unknown master, the Alicorn Sisters desperately try to uncover what happened all those years ago.

This story is a sequel to Ascend

Congratulations, Twilight. With Celestia and Luna on their constitutionally mandated vacation, you're in charge of Equestria. The position of Regent is an honored and hallowed one. But maybe it's a bit early to congratulate you. After all, whether it's a nobility jealous of your ascension, or a military unhappy with Celestia's decisions; one thing's certain: your reign will be anything but peaceful.

This story is a sequel to The God Empress of Ponykind

One thousand years ago, Luna, Warmistress of Equestria and sister of Empress Celestia, fell to the powers of Chaos and plunged Equestria into a brutal civil war. The Traitors were defeated, but not before Luna made the ultimate sacrifice and was sealed away in the Immaterium with only the soul of a slain Primarch to keep her company. For a millennium she has been locked away, waiting for a chance to return to her home and her sister.

Now, she has been freed from the Immaterium, and as she takes her first steps in a new Equestria, one ruled by the powers of Harmony, only one question remains:

Does Equestria still need the services of a Warmistress?

This story is a sequel to Princess Celestia The Changeling Queen: Stories Behind the Mask

At the Royal Wedding, Chrysalis and the Changelings were revealed to all of Equestria.

But another mask was torn away that day. A mask born for a thousand years. A mask created on one promise. A mask, that has become synonymous, fused, to its bearer.

A mask that when ripped off, causes Twilight, her friends and Luna to question everything they ever knew about the one pony, one very important pony.

At the Royal Wedding, the meaning of the phrase 'Princess Celestia' changes forever.

NOTE: Chrysalis is NOT Celestia!!! That'd be impossible to pull off.
