Four hundred years ago, an alien warp gate was discovered that connected Equestria to the Koprulu sector. A deserted sector of spaced filled with centuries worth of abandoned alien technology. That technology advanced Equestrian civilization hundreds of years into the future. One hundred years after its opening, that warp gate would close, trapping many citizens of Equestria on the other side. Cut off from their ancestral homeland, their descendants have grown up to a life filled with war and chaos, fought using technology never meant for pony kind.

On a quiet little colony, three young mares enjoyed a relatively happy childhood. During one of their usual friendly outings, they make a discovery that will change their lives forever. Their peaceful childhood comes to an end as the now adult cutie mark crusaders are about to find out just how hard life in this sector of space can be.

Additional lore on the factions can be found here if you are interested.

The owner of SweetieDrop Shop has been bedridden (well, obviously). In other words, the confectionary store has been closed for awhile and two unicorns have a cream colored pony to care for. Can Lyra and Tootsie Flute handle the changes happening to Bonbon while she's stuck on the mattress and under the blanket?

Pandinus Imperator (You can call him Pan, he won't mind) is knocked back in time during the Canterlot Invasion, and accidentally kills King Sombra on arrival. Instead of being executed, the changeling is surprised to find himself being hailed as a hero, and is promptly put on the throne as the new monarch, the Crystal Emperor. However, Pan now faces a great many problems, among them Celestia and Luna, who seem certain that the changeling is secretly up to no good, as well as several political factions secretly plotting to undermine his reign. There's also the tiny problem of the constant snowstorm that threatens to cut the city off from the outside world permanently.
The Crystal Ponies need a hero now more than ever before. Why did they get a changeling instead?

Scootaloo has lived alone for much of her life since her parents' passing, but no one, not even her closest friends, know of her most guarded secret. But this soon changes when a young dragon comes passing by the clubhouse one winter evening. Now, whether she likes it or not, Spike intends to do everything he can to help her. However as the temperature falls, the way these two friends see each other begins to change as well, but it is still unclear if it was indeed for the better.

Twilight lives in the land of dragons with her dragon family. She is content to be surrounded by her personal library, assist her high priestess mother with her rituals, occasionally organize her high-ranking officer father's files, tutor her little brother in royal manners and sometimes hang out with the third princess.

Moondancer is princess Celestia's protégée. She loves to hole up in the Canterlot research center and eat ice cream with her friends. She is also sporadically insecure about her worth, but she knows that her friends are there to help her through. With them at her sides, she can overcome anything ; she is invincible.

Simple wedding invitations would be the things to disrupt the surfacing tranquility. Except they are not simple wedding invitations. They are entrance tickets to a sinister plot and the gateways to a war between the three empires.

This story was inspired by Twilight: The Dragon Sorceress written by Wicked DG. The premise might be very similar, but I expect my way of handling it, and by extension the end result, will be completely different.

Please note that this story was planned before Gauntlet of Fire. The elements presented in the episode will most likely be completely ignored.

Diamond Tiara has always enjoyed picking on the Cutie Mark Crusaders. But one day, she finds she's gone too far, and everything for her comes tumbling down. But help may come from the most unexpected of places...

Started before season four, and does not take season four canon into account.

This story is 100% Diamond Cutters Approved!
Note: If reading this inspires you to write your own Diamond Tiara fanfics with similar premises, send me a link, as I'd love to see them.

Ruby Pinch and Dinky Hooves' long time rivalry has gotten in the way of progress! Luckily, their magic teacher, Twilight Sparkle, has come up with an idea of reviving the two bitter rivals' friendship. And what could revive a friendship like a special magic exam? Nothing. Nothing at all!

Will Twilight's plan succeed? Or will her plan end up adding flames to an already heated rivalry? Only one way to find out!

Quick Note: All characters are meant to be a few years older due to this story taking place a few years after the events of FiM.

When a mansion appears out of nowhere in the outskirts of town, The Mane 6, are all invited to a housewarming by Specter Yield, the owner of the strange mansion. Hours after they leave to attend the party, the Cutie Mark Crusaders find themselves in this mansion. Eventually, Sweetie Belle finds herself alone in this massive mansion, trying to save her friends, and discovering the truth behind this haunted mansion. Will she be able to rescue her friends... and possibly all of Equestria from the ghostly presence?

This story is a sequel to Split Second

Twelve years ago, she broke time. Two alternate timelines exist, each with a different version of Twilight Sparkle. Both versions of her are able to see the other. In this timeline, Sparkle is a Necromancer.

Or rather, she was. Sparkle is dead now, not that she cares. She's got a new body. With Thorn (her undead dragon son) and Cobalt (her apprentice and an assassin for hire) at her side, she's ready to take on the world. Again.

This story is a sequel to Split Second and won't make sense without it.
This story also loosely shares continuity with Lupine Tree. Reading that is not required.

Princess Celestia had a good day. Luna had been going out more often and was becoming quite fond of nightclubs, her dear niece Cadance had formally announced her pregnancy—though, privately, Celestia felt she was too young to be a great aunt—and, of course, Twilight, her beloved former student, had taken on her first student and Celestia couldn't be prouder! Yes, it had been a good day.

Celestia Sol woke up much like she did every day the morning: sun waking her as it danced upon her eye lids. Wait, the sun? Celestia's eyes snapped open to reveal she was in Twilight's old room in the observatory. On the other side of the room was a smaller bed where a small dusky unicorn was drooling on her pillow.

Clearly, it must be Tuesday.
