There goes the neighborhood

Just a simple man with a simple job...

Well that last part is a lie, my job might seem simple, but it any thing but; that's the life of a nuclear physicist. Most of the time the job is boring since it is the same thing day in and day out, each shift wearing down on my brain little by little. One day a malfunction occurs that will change my life forever, will I adjust?

This story is a sequel to A Drunken Night and a Cup of Tea

Vinyl just wants some time to drink a cup of tea and have a little snack. Unfortunately, she unleashes the oldest argument in British history.

Note: Reading of the former story is not required, only recommended, and this was also mainly written during a tea craving.

The door of the Chamber of Secrets is just ahead, and Harry Potter has no clue what kind of changes will unfold once he passes it. Monsters will become friends, friends will become monsters, and Hogwarts itself will change completely.

"Ahem." I had no clue what to say. This was the story of my life I had to introduce, and no one told me how it ends. "Well, I guess since we're all here we might as well enjoy this. It's a bit of a rocky start, I think, but there's a good bit right at the—

"I'll be honest. I have no clue if there are any good bits in it. Be my guest, though. It's not like you have to fight ancient monsters and dangerous wizards alone."

The Doctor is on the run, from an adversary that has pursued her across all of space and time... the last enemy there can ever be. Fortunately she has family and some good friends along to help!

A crossover based on Jodie Whittaker's Doctor. Also explores the question: what if Time Turner wasn't the Doctor all along?

This story is a sequel to Convergence

Equestria was just a game, one of an endless number of semi-illicit online games created to take advantage of the ubiquity of cheap augmented reality hardware. But that changed, when for no reason anyone knows, the virtual population of Equestria woke up.

Two decades have gone by since then, and the world has been transformed. The former game network has grown to encompass the backbone of trade, infrastructure, and research the western world over. Its vast computational resources have given rise to an infinitely subdivided world of overlays and sublayers, coterminous with the various cities and towns within Equestria. Every person in the modern world is assigned a Synth, a pony personal assistant that adapts to their needs and helps them access those parts of the world governed by Equestria's systems.

It is a world Dakota barely remembers, thanks to an automobile accident that turned most of her body to mush. But thanks to the medical miracles created by joint equestrian-human research, her life is saved by a remarkably new series of implants.

But Dakota isn't content to sit around while her body slowly knits itself together. There are unanswered questions to answer, questions that will ultimately lead her to the oldest mystery of both worlds.

After the defeat of Pony of Shadows, Somnambula returned to her old village. She doesn't quite feel at home in this new world where she feels out of place and where almost nothing is familiar to her.

Turns out that the sphinx hasn't changed much either, and can really hold a grudge.

Somnambula went off to defeat the Sphinx, in the hopes that she would save the prince.

As it would turn out, she might need saving instead...

This starts out as a comedy, but then transforms into an adventure. It would be slice of life, but the pyramids in Southern Equestria could be on the very edge of the region itself.

With an age-old threat poised to devastate Equestria, the Princesses gather to use a spell left behind by the great Star Swirl the Bearded in order to ensure their victory.

Now all four have become an entirely new being, with her own thoughts and feelings. And in order for the Princesses to return, she will have to die.

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:
