After an argument with Luna, Celestia realizes that she is the only creature in Equestria who cannot sleep in. She enlists Twilight to help, and the two of them come up with a spell that will allow her to spend the night on a different world. Unfortunately, all their research failed to reveal that the world they sought was populated. Now, the Princess must decide whether to continue with contact, or destroy the only non-Equestrian witness to their existence.

This story is a sequel to Scion of Chaos

After returning to Ponyville from Canterlot, Sweetie Belle tries her best to find her place amongst friends and family and to remember what it feels like to be home.

This story takes place 4 days after the finale of Scion of Chaos. (I recommend reading that first, if you haven't already)
And set 5 years later is the sequel story: A Heart of Change

Thanks to Rameslack for his amazing cover art.

Magic is bleeding out of Equestria and into another realm, a realm where magic does not exist. Twilight must stop the flow of magic before disaster strikes. Can the natives of this realm be of help? How do sapient beings function without magic anyway? What's this about a cartoon?

Takes place shortly after season four.

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.

It is the year 2038, and the Earth is slowly being consumed by a space-borne monstrosity dubbed the Black Tide, which is using nanotechnology to remake the planet into something hideously alien.

Erin Olsen works for Project Harmonics, humanity's last-ditch effort to find a new world before the Tide can wipe them out. But when that world is found, and it turns out to be occupied, Erin will need to find the courage to face the unknown in order to save the inhabitants of both worlds.

This story is a sequel to Twilight Sparkle of the Royal Guard

Between castle gossip, professional rivalries, a blooming romance, and a mysterious malefactor still at large, Decurion Twilight Sparkle has a lot on her plate. Hopefully, she'll make a few new friends as she moves towards the destiny she's chosen for herself.

As per usual, big thanks to Magello for the rad cover art!

This story is a sequel to Founders of Alexandria

When every human on earth either vanished or was transformed into an Equestrian pony, human civilization ended. That did not mean, however, that the survivors were content to let mankind's legacy rot and be forgotten. In every corner of the globe, ponies and other stranger creatures joined together and did what humanity has always done: survive.

With the help of their ingenuity and a little Equestrian know-how, many of these little colonies would rise to become great cities, and eventually new civilizations. But after such a dramatic transformation, could anything of their original human character survive?

There is one pony whose survival depends on making sure it does: Lonely Day. Transformed into the avatar of her near-extinct species, Archive may live to see all that newly transformed mankind might become. If, that is, she can ensure they never forget what they were.

The road to civilization will not be a smooth one. Before Equestria's universe drifted apart, terrible dangers crossed to earth, dangers earth's pony population may be unprepared to fight. Nor is humanity itself entirely extinct, thanks to careful preparation and powerful technology. Cooperation with the Human Preservation Initiative might be difficult, but it might also be the ponies' only hope.

Through many years of struggle there will be at least one witness: the eternal Lonely Day.

Continued in: Earth Without Us!

Until yesterday, my life was no different than anybody's. Go to work, pay the bills, sleep. Today, I woke up to a world without humans. The streets are empty, the power grid is running down, and not another soul is in sight. That might not be the worst thing, if I wasn't also a pony.

Where is everyone? Why is this happening to me?

Will l stay sane long enough to starve?
