This story is a sequel to Tantabus Communication Protocol

What started with laziness and a tiny slip-up in arcane intelligence creation has blossomed into its own being. With Luna's blessing, the second Tantabus is free to flit around the dreamscape as it pleases, unburdened by oversight. And what pleases it is making good dreams. Who couldn't be happy by making others happy?

As the Tantabus settles into its life, its horizons keep expanding, forever revealing more of the world and of ponies. There's always new things to learn. New dreams to spice up. New nightmares to beat down. New ponies to help. New ponies to annoy.

Don't tell Luna about that last part.

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:

A thousand year absence from the world would be disorienting for anyone, but when your job is Head of State, understanding how society has changed during your interregnum is vital. Princess Luna, banished in the age of the longboat and the longbow, has returned just in time for the launch of the tablet computer. With the help of her sister, she undertakes to understand the history she's missed and the people she finds herself among, in order to resume the duties of her title.

This story takes the form of a series of conversations between Celestia and Luna that take place months and years apart. It is openly concerned with political ideas and how societies are organised, and not at all concerned with monsters and magic beyond the conceit of immortal monarchs. The Alternate Universe tag is there because I will be ignoring every single one of the thousand year catastrophes that occur in the show after the Nightmare Moon crisis, the retirement of the Princesses, probably the presence of any other Princesses, and anything else in the show I feel like ignoring, because I find them irrelevant to the themes I want to cover.

In short, if you wanted The Audience with ponies, I got you covered.

This story can be considered canon to my comic works such as The Sunjackers, and my other associated worldbuilding projects, and uses the same date system as them (ie. roughly matching our own, with the return of Nightmare Moon happening the same year as the episode aired, 2010). May also be your jam if you like Equestria At War, but not affiliated at all.

Somewhere in the multiverse, there is a bar. It's small—the kind-of a hole-in-the wall place which you might find open late at night while walking down the streets of Canterlot City in the 1920's.

But unlike most bars, this one is not actually there… or rather, not where you think it is.

The entrance to Sunset's Isekai will be found in passing; an archway made of stone, emerging from a wall that you could have sworn had nothing there before, and in fact seems impossible to actually lead anywhere.

There, a door of solid oak—lovingly worked and stained to look almost golden-red—with a thick, crystal version of Sunset's cutie mark at eye level awaits visitors under the soft light of a gas lamp.

This door opens to all worlds, and can only be found by those that need that drink to be just the right type of different.

Note: This fic is best read like nursing your drink - Don't rush it. Enjoy each flavor for what it is. Don't mix it all up by reading it one chapter after the other in one sitting. It's intended to (mostly) work in a way that each chapter can be read without having to tackle through the rest of the story. (Also, for the last time, the concept for this is NOT based on Restaurant to Another World or any anime.)
