The princesses gave their magic to Twilight to prevent Tirek from stealing it. As a result, they end up stuck in Tartarus.

Marvelous place, Tartarus. Really brings ponies together. The fact that things manage to go downhill here says a lot about the wonders of family and alicornhood.

All her life, Professor Lyra Heartstrings has passionately sought scientific proof for the existence of "human" beings, a technologically-advanced race of sentient creatures who theoretically ruled the world in a time before ponies. But now that Lyra stands upon the brink of Equestria's most important anthropological discovery, she's haunted with the gnawing thought that not all projects that begin should necessarily be finished.

(This is an entry into Obselescence's The More Most Dangerous Game Contest, with the Prompt Being a Re-Interpretation of JasonTheHuman's classic fanfic, Anthropology.)

The discovery of a tiny extraterrestrial object within our own solar system makes a strangely equine alien race aware that the Earth is inhabited by an intelligent species, and they're on their way to come visit.

But since space is a really, really, really big place, they aren't going to get here for about a thousand years. They do have FTL communication, though, so while we wait maybe we'd like to be pen pals...

The Long Patrol is an extension of the crown. It brings the rule of law and the princess's banner to the far reaches of the kingdom, the places where harmony fades and the wild chaos of nature still reigns.

In times past, all the tribes took part in the patrol. Today, it is mostly pegasi and a few gryphons. The distances they travel are simply too vast for anyone without wings.

Like most gryphons who join, I wanted to get away from my kind. I dreamed of the adventures I would have and the friends I would make. I certainly got those.

I just wish the price weren't so high.

The tyrannical Shadow Stallion oppresses Equestria, coating the land in a thick layer of clouds, tightly controlling the population. Three children, the unicorns Celestia and Luna, along with a Draconequus, Discord, must live up to their fate. They must find the Elements of Harmony and take up their rightful place as Equestrias new gods and saviors.

Adventure and Friendshipping mix, intended to be a possible prequel to the show. Featured on EqD since January 09, 2012. Six Stars.

When Twilight Sparkle was just a kid, her best friend was a girl named Sunset Shimmer. Though their friendship had a bit of a rocky start, they quickly became inseparable, no matter how much everyone thought of them as ‘weird’. They were there for each other.

Were.

Years after the tragic accident that tore them apart, Twilight is determined to move on from her loss, and she sets off on an independent research project to investigate the strange happenings at Canterlot High. Little does she know that she will soon come face to face with what appears to be a literal ghost from her past.

Takes place after Rainbow Rocks, but was written before Friendship Games and does not take it into account.

The history of Equestria spans dozens of centuries, and many terrible foes have risen up from the past to threaten the future once more, only to be defeated.

When a vicious and powerful enemy older than any Twilight, her friends, or even the Princesses have faced before returns, they will have to reach out to an ally just as ancient for help... but is she still the heroine she once was?

This story takes place after the end of Season 3.
