This story is a sequel to Advance Warning

Late Season 3. Twilight Sparkle is moon-gazing, when she receives an unexpected visit from Princess Luna. The dark Princess tells Twilight of the Moon, and a long-forgotten tale of the Age of Wonders ... and how the ponies of that time achieved greatness, yet ultimately failed of their true promise. Inspired by the PonyPOV fanon.

Now has a TVTropes page here.

Tirek has won. As he escapes from his cell in Tartarus and wreaks havoc across Equestria, he has taken down the Princesses and has stolen all their magic from Twilight.
But during Tirek's victory... someone new shows up.

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.

Far from civilization, in places still left blank on all maps, one can sometimes find wonders of magic that predate even Equestria. Beautiful and dangerous, they’re a silent reminder of the world as it once was. But they’re also a threat to the travelers from the growing Principality of Equestria, so when Princess Luna discovers an unnatural blemish in the texture of her dreamscape, she doesn’t wait to investigate it.

Little does she know that the creator of that blemish is already waiting for her.

One night, Twilight notices something odd as she's nestled in bed with Rarity: her hair smells different, just slightly. The next morning, her tea tastes a little bit less sweet, and the flowers outside smell somewhat less fragrant. Out at a cafe together, the music doesn't sound as sharp and clear, and Rarity's new dress feels marginally less smooth against her coat.

Twilight just wants to know what's happening, so she can fix it. It has to be temporary, after all.

The Grand Galloping Gala! An event that six mares had looked forward to for a long time, only to be met with disappointment when their dreams failed to come true. But what if they had gotten everything they had wanted?

Well, that would leave poor Spike all alone for the rest of the night, with only bad vibes and Pony Joe to keep him company. That is, until a certain Princess makes her royal return....

Eighty years after the events of The Dread Chitin, Equestria is a radically different place. The arcane science of the late Duran Thirk and the information found on the Star League library core have combined to catapult the nation's science ahead by hundreds of years.

Now, facing the possible aggression of a completely unknown alien power, Twilight Sparkle and her friends have to gather together once more, leading a crew of the best ponies they could assemble in a voyage outside their own star system. They seek to learn about their potential foe, to explore the galaxy around them, and possibly find allies and friends to stand alongside them. Who knows what they will actually find?

Stranded on a hostile, alien world, Twilight Sparkle and Rainbow Dash must depend on one another and a fellow alien castaway if they want to return home to Equestria.(originally published on FFN)

Celestia has been raising the sun later in the day than normal, and setting it earlier than usual. Luna wants to find out why and help her sister with whatever problem she's facing. But help can be hard to give when your sister is in the middle of a depressive spell that will last for weeks more, one that she always faces at this time of year, every year.

Ragar the Ageless has seen many things in his non-life. He has seen fields of cotton candy, the wails of the soon-to-be-dead chanting in chorus. Once he even saw a unicorn. Well, there are a lot of those in Equestria, so maybe that one was less noteworthy. But still, he's seen a lot. Now he wants others to see him in all his glorious evil. The only issue is he's not so good at it.
