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.

The glamorous unicorn Opalescence is haunted by bizarre recurring dreams of a world in which she and her friends are all animals. But as vivid as these dreams are, surely they're just dreams, right? There couldn't actually be a parallel universe somewhere where they're little more than pets ... right?

For so long, Chrysalis, Tirek, and Cozy Glow stood paralyzed in their stone cacoon; unable to move. To speak. To do anything. But that didn't mean they couldn't see or hear everything around them. For age after age.

The Russian version here.

Where DO foals come from? The Cutie Mark Crusaders don't know, but they intend to find out!

Rainbow Dash flies east.

After a harrowing and dangerous quest, Twilight Sparkle and her friends have recovered Excelsior's Ecstatic Codex from an evil zebra cult intent on ending the world. The Codex, one of the greatest works of dark magic ever forged, carries within its pages a limitless collection of vile, twisted spells, all specially devised for anypony who opens the cover.

What do you do with a book of dark magic? If you're Twilight Sparkle, you put it in your library. Because that's where books go.

After all, books are for everypony.

Leave it to Twilight Sparkle to create the greatest spell of the past century – and then want to destroy it.

It's too dangerous to use, she says. It's too tempting. It can't help you the way you think it can.

Well, Starlight Glimmer knows a thing or three about temptation. She'll prove to Twilight that this spell – this magnificent book – is too important to destroy. That it can help ponies.

She just has to survive using it, first.
