After Rainbow Dash's magnum opus fan-fiction, Daring Do and the Ring of Destiny, fails to attract the response from her editor, Rarity, that she expected, she copes with her feelings of rejection in a manner befitting of her established reputation: by parking her cloud mansion above the boutique and drenching it in a watery apocalypse.

It can takes the average newborn foal a day to walk. Sometimes it takes longer. Sometimes something is wrong. Sometimes a foal bounces back.

From Corejo:

As a disclaimer, the prose gets a little cluttered toward the middle of the story, when he’s working on his diagnosis. All it takes is a little care in parsing the information, and you’re rewarded with a brilliant origin story that will leaving you smiling and saying, “why didn’t I think of something like that?”

It’s short. It’s sweet. It’s worth your time. And who doesn’t love little snippets of why something is the way it is in the show? I definitely do. Go check it out.

It has been two hundred years since Celestia’s funeral, and Equestria has changed. Mighty ships sail between the stars, great cities scrape the skies of half a dozen worlds, and what was once a humble nation has become a vast empire.

And now, Twilight Sparkle writes to her dearest mentor once again.

As of Season 4, LttS is fully re-integrated with canon.

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.

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.

This story is a sequel to The Monster in the Twilight

Now that Luna has returned to the throne, and the aftermath of her brief appearance as Nightmare Moon is being cleaned up, the story is over. Right?

Not quite.

Twilight Sparkle had nearly been destroyed in the chaos of Nightmare Moon’s return, but now with the assistance of her five friends, she is facing a fascinating new world filled with wonderful things. No longer the scarred monster who nearly destroyed Canterlot and raged through the Everfree Forest for over a decade, now she has been healed by the Elements of Harmony and is living at the edge of town with her adoptive mother Zecora. Not all the fears of her past can be left behind that easily though, and now she must face the consequences of her actions as she faces the most daunting challenge of her life.

Ponyville.

Letters is a sequel to the alternate universe story The Monster in the Twilight. In this story, Twilight Sparkle exchanges letters with Princess Luna, two ponies with a common problem of fitting in and making friends after the destruction of Nightmare Moon.

Normally I would try to talk you into reading the sequel even if you haven’t read the original story, but in this case, you’ll probably be more confused than entertained. But go ahead. I don’t mind if you don’t read the first story. You’ll never find out what an Urlock is, but that’s fine. It’s your funeral.
