A hack author (from "Extremely Terrible and Horrifying Stories" and "Mystery Pinkie Pie Theater 3000") is attempting to write his next magnum opus. Then Pinkie Pie happens.
Not the most original idea in existence, but hey, this is my take on how it would play out.

When they began to read the ancient book Twilight and Spike only had the slightest of ideas what it could possibly be about. As the illuminated inks revealed to them an image of Princess Celestia locked in combat with a massive dragon and his sons they realized that the song written upon the aged pages was telling of a long forgotten battle...

... and that the Celestia they know and love is capable of things they dare not imagine.

Inspired by the image "By Celestia's Might" by John Joseco.

A day in the life, and a glimpse into the mind, of Ponyville's favorite mail carrier and single mom. But if she had the choice of any one day for everyone to read about, it probably wouldn't be this one...

Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Derpy explains her medical condition to her daughter.

Everypony has their secrets. Their own 'guilty pleasures' that they try to hide even from those closest to them. What kind of secret does Twilight Sparkle keep to herself, and can she indulge in it when she has the whole library to herself?

When the light dims and the flame burns out, the magic inside us all will forever endure.
