I was not prepared for this...

Centuries ago, the Crystal Empire fell to the evil of King Mi Eterna Sombra. Wounded by the unicorn's dark magic and corrupt heart, the Empire retreated into the ether and took its citizens with it. Many ponies at that time believed the Empire would never be seen again.

Now, in AD 1358, the Second Diarchy, the Empire has returned. With a reluctant princess and a vengeful moon-goddess in tow, can Twilight Sparkle and her friends (both pony, human, and other) succeed in saving it and restoring the Empire to its former glory? What secrets lay in the shining city of Adamanetia?

This side-story takes place between A's and StrikerS. Please refer to the Magical Pony Lyrical Twilight series for information.

Something has happened and Twilight finds herself in a strange and dark new world. The Bipeds here have strange magic, advanced technology, and a lot of problems. She needs a few friends, and they just might need her. WORM crossover. Deadpan29 has created some great supplementary material that is canon to the story.

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:

What if Nanoha never became the White Devil?

It was such a small wish...

The joyous occasion is interrupted, however, by the appearance of a new threat; a set of mysterious mages armed with powerful Devices and daunting magical prowess. Who are these mysterious people that call themselves the Wolkenritter? Who do they serve?

Twilight and her friends, both old and new, are once more forced into conflict. This time, however, Equestria's future may very well hang in the balance.

The lost children...

Ten long years have passed since the Book of Darkness Incident. In those ten years, Equestria has come into its own as an allied world with the Time-Space Administration Bureau. Though diplomatic interactions between the two are still rocky, cultural, technological and academic sharing has helped to smooth over the bumpy relations to some degree.

In an attempt to foster better relations between the two worlds, the Bureau has established a special joint training task-force, bringing on some of the brightest and most talented mages in all of Equestria. A group of young humans, ponies, and... others have been selected as candidates for this new, experimental group.

Unfortunately for the humans and ponies of the Resolution Instructional Operations Task Force, things are not all they seem. A new threat is brewing; one that may destroy the fragile peace the Bureau has long sought to maintain... and dredge up secrets of a past long, long forgotten.
