Strange symbols have started appearing all across Equestria that nopony can read, except Discord. As he comes to grips with what this message means, he is determined that nopony find out its secret. If they do, absolutely everypony in Equestria will die.

This story is a cosmological crossover with The Three Body Problem trilogy by Cixin Liu, and thus contains spoilers for that universe. But can be read without prior knowledge of that story.

This story is a sequel to Best Hell Ever

Once upon a time, Twilight went to hell. It wasn’t that bad. It was pretty great, actually. It had a library! A big one. Like, bigger-than-the-universe big. But then Twilight went and got herself kicked out of hell, and now she’s depressed.

There’s only one logical solution: with Starlight’s reluctant help, Twilight is going to break into hell and invade its library. Oh, it’ll be tricky — trying to find one specific location in an infinite dimension tends to be a bit hard — but the infinite knowledge it’ll provide is too good to pass up. Twilight will find that library if it kills her (which, since this is hell, isn’t the worst thing ever in the grand scheme of things).

There is absolutely no way this can possibly go wrong.

This story is a sequel to Stardust

Times are changing for Equestria as Twilight’s return brings with it news of people and cultures from beyond the peaceful world everypony knows. Aid and volunteers are freely offered to help the besieged humans of Earth because every Equestrian knows that’s what good friends do. Unfortunately, making friends can also have the unintended consequence of making enemies.

When the monsters besieging the humans strike at Equestria with a level of brutality not seen in over a thousand years, the cry for help is sent to all the kingdoms of the world. Honored allies step forth to fulfill ancient treaties and oaths. Enemies, old and new, bury their grievances. An alliance never before seen in Equestria will be created to combat the monsters from the void.

And because of these events, a grim but welcome sibling to the XCOM project is born.

Isolated from her friends and taken prisoner in the middle of a war, Twilight must deal with the very real dangers of being percieved as an enemy as well as the nightmares of her arrival on 'Earth'. Can she overcome her own fears and the fears of her captors? Will the wayward unicorn's assistance be a boon or a curse to the 'humans?' Most importantly, will she ever find her way home?

"In short, it's a story of friendship and plasma rifles, with the emphasis on the friendship. The characters are well written, the XCOM setting is fleshed out very well, and the story is compelling. If you love XCOM, you'll love the story, but even if you've never heard of it, it's more than worth giving the first 3 chapters a read.

There's excellent action later on, but the real strength lies in the collision between the friendly and naive world of Twilight Sparkle and the desperate world of humans fighting a losing war for survival and willing to do anything to turn the tide."

Ballpoint Smudge has one job. It's not an easy one, but it's one he's determined to do to the best of his ability. The only problem is that as soon as he meets Twilight Sparkle, everything he's ever learned about princesses goes flying out of the window. He was expecting her to be regal, haughty and bossy. Instead she's warm, friendly and welcoming. Perhaps she's genuinely a nice pony? Nah. It's got to be a test.

Based on an idea by Ambrose Bierce, from his excellent Devil's Dictionary. Just look up 'Insurance'.

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."

Big Mac doesn’t say much. That’s just his way. However, when a routine medical exam reveals he’s going to lose his voice, he decides he’d better get his last round of speaking in while he still can. Saying a few last words to his friends (and asking out a certain schoolteacher) is all he planned on doing. If only he understood the full repercussions of opening his big mouth.

The original version of the story took 12th place in The Writeoff Association's July contest, "A Matter of Perspective"

This story is a sequel to The Sun Burns Brightly

When you're the immortal ruler of an entire kingdom, the most important quality to possess is a passion for your work. No princess can rule her nation if she can't find it in herself to give her best effort every day and night. Luna knows this better than anypony, and puts her whole heart into everything she does.

But passion, unless tempered by restraint, has a way of biting one in the flank.
