Applejack's life is turned upside-down after she suddenly inherits the full powers of a goddess. She insists that it isn't a big deal and that she's the same pony as always, just bigger. Meanwhile, everypony else starts making demands on her and placing expectations on the 'new princess'. When the constant stream of petitions and gawkers starts interfering with farm work, Applejack reacts a bit strongly. Luna, fearing the worst, is determined to rescue Applejack from corruption, further irritating the farm pony. Will Applejack accept her destiny, or is destiny what you make of it?

This story is a sequel to Elementals of Harmony

Ditzy Doo returns home one day to find an old friend waiting for her with dire news and a brain in a jar. With the latter, she will witness the answer to a pair of ominous questions: What if Jin-Gitaxias was a brony? What if New Phyrexia tried to invade Equestria?

As noted above, this is a sequel. Read the first story first, or little if anything will make sense. A certain level of gore and body horror will inevitably arise, given the nature of Phyrexia (For the card game illiterate: Like the Borg, but with more magic and much less attachment to the humanoid form.)

Cancelled after a long remission. You can see what would have been here.

Something is gathering around the bearers of the Elements of Harmony. Something dangerous. Something magical. There's only one pony with the knowledge, the skills, and the muffins needed to save Equestria as we know it.
A Friendship is Magic: the Gathering crossover, taking place between seasons 1 and 2. Here there be flashbacks, briefly seen OC's, and possibly every emotion known to man or tiny horse. Abandon all pretenses of not being a nerd, ye who enter here.

This is a fic based on the Time Loop Files, the format of which was first codified by Innortal on fanfiction.net.
Here's a brief guide.
The basic idea is, one character (the Anchor, usually the main character of a fictional setting) is looping back to the very first moments of their parent series every time either they die or some kind of time limit expires. They of course end up monumentally stir crazy given enough time.
Eventually others start to loop as well.
The reset is not always perfect. Sometimes a loop's history will be different to the "prime" loop, or canonical plot.
"Crossover" or "Fusion" loops also occur, randomly. These can involve the home loopers having a guest, or the anchor for one universe spending time in another, or replacements of one character by another.
Vacation Loops are where the Anchor (or others) decide/s "buck it" and lets off steam by doing whatever comes to mind. There's little or no attempt to maintain the original timeline.

In addition, and particularly more recently, it should be known that this story has a collaborative element to it - people may submit loop ideas or loops, ideally at the Spacebattles thread (a link to the current version of which is on the Trope page), and they may become included.

There's two page image options, thanks to Filraen - the current page image has been edited by the original creator from this work of theirs.. The other one is here:

Princess Celestia: Goddess of the Sun, ruler of Equestria, beloved Princess of ponies. She is loved by all, and loves all in return. A calm and wise ruler, she sits on the throne in Canterlot, maintaining peace and harmony throughout the land.

What most don't know is that her past is much darker: She was once a commander of legions, a warrior and scientist of unmatched skill. Thousands of monsters and abominations fell to her forces, slain in the name of an old leader, one entombed within his own throne. Free of her old form, free of the powers of Chaos, she was cast into a new realm, in a new form, with a new lease on life.

She is the God Emperor, Eternal Ruler of Equestria and Lord of the Imperium of Man.
