Probably the best thing to happen in Discord's long life was finding the magic of friendship. As much as the old Chaos Lord might complain, without it he would never have found so many that were dear to his heart.

When that heart finds itself empty, he comes to the Princess to ask a favor: allow him the opportunity to bring friendship to other dark hearts. All she has to do is lend him a statue.

The rest is in his chaotic claws.

Death tag - no horrible murder, just a few mentions and the natural consequences of time.

So many changes to get used to. Twilight can now raise the sun and moon, but all that power comes with some strange consequences. Everypony is getting used to the new order, but one pony seems to be terrified of the new ruler. Why is he like this? Perhaps a letter to Celestia might bring answers.

Now in Chinese, thanks to Flint44!

Almost twenty years into her reign, Princess Twilight Sparkle encounters something truly miraculous, something she never thought she'd see again in all her years: A hole in her schedule.

Naturally, that's when Discord comes in to discuss the contents of his hairbrush.

Needless to say, spoilers for the finale. Ineligible entry in Imposing Sovereigns II, using the prompt "Twilight/The Old."

A series of little one shots about encounters between the reader and lamia ponies, usually involving some kind of sappy light romance. Each chapter will its own story, with no crossover between them. I will continue to add 'chapters' as I do them.

Contains: Coil cuddles, constriction, hypnosis, and lots and lots of cuties!

Anon takes over Spike’s job of transcribing Twilight’s friendship reports. He does exactly what you’d expect.

Companion fic containing Celestia’s replies up to Letter 120 - To: Anon, From HRH Sunbutt written by Snow

I think that I shall never see
A home as lovely as my tree.
In its trunk I made my nest
With all things that I love best.
Books to read all night and day,
Rooms to learn and space to play;
But no more growing, no more fun;
No more soaking up the sun;
Nevermore to drink sweet rain;
Or to greet the Spring again.
There is no power or decree;
No magic spell to save my tree.

In a world of brass and steam, Twilight Sparkle had thought she had made a life-changing discovery with the invention of the telescope. For better or worse, she was correct.

Now her discovery has not only changed her life, but the lives of those she seeks out in her desperate attempt to contact the only other creature as lonely as Twilight herself.

It all would have been much simpler, but it had to be the one Twilight could only call The Mare on the Moon.

Decidedly not within walking distance, then.

Unless it's meant to be fixed

Commander Shepard remembers firing the crucible. She remembers she had to make an important choice. She remembers good friends, a lover, and plenty of loyal crewmen.

She just can't remember what her choice was. What the threat she was striving so hard to end was. Or what the faces of the most important people in her life look like.

She also has no idea how she wound up in the monster filled forest she's come to call home for the past eight months. Or how she picked up a snarky A.I. making its home in her omni-tool.

Daring Do cannot believe her luck when she is asked to help explore the most ancient tomb known to ponykind. But terrible danger awaits her, for beneath the earth rests something beyond equine understanding.
