Time after time, through chaos and through wars, Princess Celestia prevailed.

Of all the terrible forces she could have fallen to, Flim Flam Industry was the last one anypony had expected.

Mis-communication has started many a war, but in this case maybe calling it a war was too generous.

The "war" is over, Twilight has successfully orchestrated a bloodless end to the Griffons' aggression, but only now does she realize that there is more to winning than she had first assumed, especially against a nation that holds war as a central part of their culture...

Now Twilight must deal with the aftermath while facing a challenge she never anticipated: being seen as a conqueror.

This can be read alone, but I recommend reading the letter that started it all for a chuckle and a little exposition. This series of expositional one-shots can also give some additional world-building.

Twilight Sparkle - magus, heroine and Princess - has learned of worlds overlapping Ungulatia in space and time. Though this has been a well known phenomenon, safely traveling to these other worlds has always eluded pony mages. But now - after years of research and careful experiments - she prepares herself for the most audacious of all experiments: stepping hoof on the surface of an alien world and returning safely! What wonders will she find once she walks through her magic portal?

This assumes that Equestria Girls never happened.

As fate would have it, Twilight had to hatch a much bigger egg this time.

PRINCESS TWILIGHT SPARKLE: DEAD AT 18

TELEPORTATION INVARIABLY FATAL, WARNS LEADING SCHOLAR

One look at the headline of the Canterlot Times and Twilight knew that she should have slept in today. But at least none of her friends would be silly enough to believe she was killing herself every time she teleported, right?

Welp.

Now on TV Tropes.

In the chaotic period following the fall of the Covenant Empire, the Shipmaster Vraal Rutaen does his best to ensure the safety of his race. For years he and his crew have fought countless threats, searching at the same time the precious Forerunner technologies on which depends the future of the Sangheili. But this is not enough. The Sangheili, once proud warriors that fought in name of glory and honor, are now without a true purpose to live, risking the extinction. But when they discover accidentally a new planet that defies every law of physics, maybe they've also found the answer to their existential question. All depends on the first contact with the inhabitants.

THE STORY IS NOT ABANDONED. I'M JUST TOO BUSY TO CONTINUE IT AT THE MOMENT, SO PLEASE STOP ASKING WHEN I WILL UPDATE IT. READ MY BLOG FOR DETAILS.

Principal Celestia has accidentally fallen through the mirror into Equestria, and it may be a bit before she can go home. Until then, she has to learn to cope with a strange world, in a strange body.

At the same time, Twilight has to figure out how she can help her new guest while keeping Equestria from freaking out over the presence of a second Celestia, and Sunset Shimmer has to figure out how she is going to make amends with those she had left behind in Equestria, while keeping an eye on her Principal.

Disclaimer: Since I wrote this description ages ago before I even knew the plot, the story is mostly pure comedy in the beginning, with eventual Sunlight and Chryslestia shipping!
