Spike led Thorax into the throne room of the Crystal Castle confident he could convince the others that the changeling could be trusted. That he meant no harm, and instead wanted to be an ally and live peacefully with them. That he could make them see Thorax for what he really was. That they could befriend the changeling and accept him as one of their own.

They didn't.

And consequences followed.

This story is a sequel to Memento Mori

I have seen the mare who does not sleep.

Shall I tell you about her?

(Written originally for the Writeoff Association. The Prompt was "Forbidden Knowledge".)

Apple Bloom wants to see her parents, the Cutie Mark Crusaders want their cutie marks, so they do the the only logical thing and try to raise the dead.

Can these three amateur necromancers pull it off without bringing back something twisted and wrong or a horde of the undead?

Tagged 'Sex' for a bumper crop of farm innuendos.

This story is a sequel to The Celestia Code

When the monsters created by the dark crystal engine escape their prison, it's up to Princess Twilight Sparkle to deal with them. She gets help and advice from Princess Luna, but things don't go as planned. In fact, when a pony who relies on logic and rationality tries to navigate the stormy seas of emotional entanglement while simultaneously saving Equestria from a horde of evil creatures intent on destroying everything they encounter, nothing goes as planned.

Goodreads Page
100% Approved by Twilight's Library!

The Badass Twilight tag applies more than ever, but please note the new tags.

This story is a fairly direct continuation of The Celestia Code. You might be able to follow it without having read The Celestia Code first, but it's better if you do.

The sequel is here: The Twilight Enigma

Most excellent pre-reading/editing done by the erudite AcademicPony and the dapper statoose!

Princess Celestia has asked Twilight and Applejack to investigate an ancient artifact in the Foal Mountains. However, trouble arises, and their efforts prove to be in vain. But as an old saying goes: If at first you don’t succeed, try, try, try, try, try again.

If only this wasn't messing with their wedding plans.

Practice makes perfect. And Princess Twilight wants everything to be perfect. Especially the end of the world.

This story takes place during the Season Five finale, "The Cutie Re-Mark". As such, there are spoilers ahead.

Starlight Glimmer's plan is working. All she has to do is upset Rainbow Dash's rainboom-creating race in the past, and Twilight Sparkle's connection with her friends will be severed. And she's done it. Repeatedly. Sure, Twilight can go back in time to try and stop her, but Starlight will always be brought back as well. No matter what Twilight tries, no matter how many times she returns, she can't stop Starlight. They're evenly-matched, and it's much easier to disrupt events than it is to preserve them.

That means Starlight wins, right?

One early morning Twilight is woken up by the sound of somepony knocking on her door. To her surprise she finds Rainbow Dash on the other side, only the mare seems off. Disgruntled and panicked, the more she talks, the more Twilight is convinced there's something wrong. What happened to her?
