Every week, in secrecy, Scootaloo goes to her parent's house. She's afraid of other ponies finding out because her parents are rather... strange. But maybe things aren't as they seem, as her parents are about to tell her something that can turn her entire world upside down...

Throughout all of history, one concept has kept both the written and spoken word from becoming an unintelligible mess. That concept is that most holy of grounds known by some as "grammar." It sets down rules for language to follow, and keeps it free of distortion.

Yet something is wrong. The rules are failing. And only one pony so much as suspects that something is wrong. Something that goes deeper than a simple appearance of errors. Something that could be an attack on the very root of language itself.

It's no mere coincidence that the possessors of the Elements of Harmony all wound up in Ponyville. With careful planning, convincing, and a bit of luck Princess Celestia led six mares along the right path that would forever make them the best of friends.

But first she had to find them.

There are stories which define us. Stories that inspire us. And there are stories that damn us.

These are the Old Stories, tales from before the dawn of Equestria.

==Originally written Fall 2011== Equestria Daily Post==
After a long day of ruling Equestria, the Royal Sisters need a chance to unwind. Luna's solution is a few glasses of her once famous Moonshine, a drink distilled from moonlight. Celestia has been sober for a thousand years, but the temptation to have "just one" glass proves too great. Yet, when that one glass turns into several, it's Twilight who will have to deal with the princesses when they’re drunk off their flanks.
