After being sent to the caves under canterlot, Twilight sparkle finds a being older than ponykind itself- inspired by the this day aria

“Legends. Thousands of them have been spun throughout history and thousands more will be spun. Some sing of heroes, others of villains. But one legend, lost to time, sings of a single homesick soul in a world not his own.”

Mark Tyr went to a local convention cosplaying as Shirou Emiya when he is almost killed in an explosion.

He still has no idea how he ended up in Equestria as Avenger.

A thousand years later, he get's stuck in Twilight's head and they have a goal.

Get him a body and get him home.

Avenger is from Fate/Hollow Ataraxia (A sequel to Fate/Stay Night.)

Twilight's dinner party to show Celestia Starlight's progress as a student of friendship was a disaster of epic proportions.

Okay, fine, that's being a little dramatic. The evening didn't go as planned of course, but some good things did come from it, it's not like anybody got hurt, and Twilight did her best (give her a break--she's new to this 'teaching' thing). So why did Celestia--normally poised and calm and understanding Celestia--look so angry? She acted like Twilight was inconveniencing her on purpose! No wonder the friendship princess was so frazzled.

Later that night, Celestia returns to Canterlot. And, after a lot of stubborn denial (and some interference from a certain being of chaos), she finally confides in Princess Luna the real reason she was so frustrated. Luna listens, comforts her, and then proceeds to do her duty as princess of the night by making everyone's evening a little more peaceful.

The night heals all wounds.

Twilight Sparkle is given permission to explore the Canterlot Caves after the invasion but, while inside, she discovers an ancient and primordial being, an literal force of nature, a creature said to be over a million years old...and it's now awake, how will she, and her friends, handle an adventure of a lifetime? Will they be able to get knowledge from a creature older than Celestia herself? Will they be able to bring it out of its well of sadness? Will they be able to show it that friendship really IS magic, or will it be driven away by their persistence of trying to become friends with it after it was betrayed and cause it to never been seen again?

Be wary Equestria for the Nine Tailed Beast has arrived!

WARNING: Major spoilers in the comments. Takes place several months after the end of season four. (Not a Da Vinci Code crossover, BTW!)

Do you see a dark tag? No, you don't. Not dark. Well, okay, there are a couple of dark-ish bits, but that's all. Not enough to warrant a tag. Speaking of tags, there really ought to be "Badass Twilight" and "Friendshipping" ones.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

My editor for the first edition of this story was Gogito, and I can't thank him enough for all the hard work he did. My editor for the revised version was PresentPerfect, and he did a terrific job of getting the story into excellent shape.

To be inserted into Equestria, it's a dream come true for anybrony!

Meet the ponies!

Have super awesome magical adventures!

Use foreknowledge to avoid all those silly pratfall moments without screwing things up and causing irreparable harm to the Mane 6...uh...hopefully!

And all for the low cost of possessing Princess Luna, denying her any real freedom or the ability to move on with her life since she's in your head and you're walking around as Nightmare Moon!

Yeah...there had to be a catch in there somewhere, didn't there?

When accidentally stumbling across Spike's diary, the Mane Six discover secrets on how Spike feels about each one of them.
