This story is a sequel to Spring Tide

On an evening warm and fair, Princess Luna comes walking to Twilight's castle, singing as she goes. Twilight, however, is not there to meet her and so Luna believes she's been stood up. Then she discovers that something far more sinsister has happened, for Twilight, picking flowers for a bouquet at the edge of the Everfree, has stepped into a fairy ring on Midsummer's Eve.

(Continuing my habit of basing stories on songs.)

It's taken months to get to this moment. Months of planning, testing, and tearing her mane out. This is one time she can't afford to fail.

Today is the day. It's cold, her nose is runny, and she's scared out of her wits, but she's finally going to do it. She's finally going to tell the Princess how she feels.

It had been a very nice day. Ponies worked, played and laughed. Wherever you looked all was well. The young pony, recently given the title of 'Princess' was just sitting out enjoying what life had to offer. Then everything changed, and it did so with a cube...

Lost in a plane completely foreign to her, Twilight Sparkle must use her skills as a leader to guide a whole town to safety. Now is the time the young Alicorn must prove her worth as a leader. Over a thousand ponies are lost to an unforgiving, eternally unchanging world. Can she save them all?

After returning from the Dragon Migration, Spike begins to feel even lonelier with an empty space inside him (even though he proclaimed the ponies as his family)... All he wants is one thing really and the only pony who can give him that is a certain lavender unicorn

A month or so after the Battle of the Bands, Principal Celestia calls Sunset Shimmer and friends to her office, for a long-overdue discussion.

Edited and smoothed over with help from the ever-patient Little Jackie Papercut.

Set in the Optimalverse, a middle-aged woman enamored of 'Equestria Online' confronts what permanent emigration to Equestria - uploading to a virtual existence - really means... but can she even hope to truly understand such a thing - and more importantly, can she trust the artificial intelligence known as 'Celestia'?

This 'Earth' is so close, and yet so far from anything Twilight described on the other side of that mirror. How is Rarity going to get back to her home when she can't understand anyponybody? And didn't Twilight say she became human, and humans didn't use magic? Yet clearly some did... and that wasn't even counting all the devices that might as well have been magical, as far as Rarity was concerned.

Who knew one strange little gem could cause so many problems? They'd taken it from her after it'd brought her straight into a lab for study, but... If she ever found it again, she was definitely going to let Spike eat it. As soon as she got home. And by Celestia, she was going to get home!

...Will Rarity ever find her way home? Is the gem that brought her to Earth the key, and is there more to the factions maneuvering around her appearance?

To complicate matters, this is an Earth recovering from its first alien invasion (Rarity being technically the second, then). ...Or does that actually explain things? No, no it doesn't. But it will.

------------------------------------------------------
To go with the Teen rating (or rather to explain it) there is light profanity and violence. I don't believe either are at a level where the warning tags are needed, but I'll mention it at least.
There may be some darker, more explicit moments in flashbacks, but I'll save those for Interludes.

With Princess Luna's triumphant return from exile, the Royal Sisters are finally reunited after a millennia apart.

But that does not mean troubles have vanished.

Shortly after her first public appearance, the loveable Princess Luna has her form reverted back to that of the fearsome Nightmare Moon, a perplexing problem that she and her sister Princess Celestia must solve.

Together, the pair of siblings work to uncover the details behind this startling development, while learning about themselves and each other as they mend their relationship. Taking a page from the past, what better way to share and learn from each other than sharing a journal chronicling their experiences?

Originally published with one chapter, this silly little tale has grown from what was once known as First Impressions Are Everything.

This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Back in their underground arcologies, the ponies' erstwhile masters deal with the consequences of the escape, all the while unaware that something lurking at the bottom of space-time wants them all dead.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.
