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!

This story is a sequel to Past Sins

In the wake of the battle with Tirek, Twilight Sparkle becomes fixated on restoring Golden Oaks Library. After all, it was home for her little family of three. But as her attempts to repair the books and tree continuously fail, her friends must take matters into their own hooves. Discord, as the good friend he is, tosses Twilight and her extended family into an unexpected adventure while Twilight's other friends get to work on the new crystal palace.

All together, they'll do everything to ensure Twilight and her family have a place to call home when they reach the end of the road.

Tired of Luna's constant nagging, Celestia agrees to give internet dating a try. Using the website www.notforeveralone.com, Luna helps Celestia go on dates with potential immortal suitors. Shouldn't be too hard to find true love, right?

You can make a suggestion for any immortal across any manner of genre or fiction for Celestia to date next. Just make sure they're immortal for it to work.

Updates every Tuesday and Friday.

Guest chapters for immortals I have not covered are welcome, since I won't be able to write about every suggestion someone has. Note that all guest chapters are non-canon from the main story, so there is a bit of leeway to them. Talk to me over PM's for any further discussion.

Thanks to my editors The Ponytrician and Garnot for all their help!

Luna attempts to distract herself from the same frustrations that she once let ruin her life.

A thousand years is quite the generation gap, so Princess Luna decides she has to get with the times. However, this isn't quite as easy as she thinks it will be...

[Complete] Celestia awakens to see an empty world, white sandstone stretching the horizon. She wanders the world as she builds it from her imagination, filling it with life, but as time passes, the world that she created begins to seem like little more than a lucid dream, conjured from the dust.

Luna has had enough of Celestia's games, and has found the perfect means of revenge. Using a long-forbidden spell, she transforms her sister into little more than a small filly, all so she could pull the greatest prank ever. Unfortunately, she soon learns that before you fool around with dangerous magic, you really need to read the fine print...

A sequel can be found here.

Twilight's got a pretty good life going in Ponyville. Her days are full of friendship, studying, and the studying of friendship. On top of that, she's a princess in a fancy crystal castle in Ponyville. Her life is as close to perfect as she can imagine it...

Except for that weird noise that has suddenly started keeping her up at night.
