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.

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 Twilight Sparkle discovers a centuries-old mystery hidden in the Royal Archives. Her investigation leads through layer after layer of deception and misdirection, setting her hooves on a path that seems to be leading to a mysterious secret. Along the way, she learns that some friendships can be very, very strange.

Book 1 of the Alicorn Adventure series.

WARNING: Major spoilers in the comments. Takes place several months after the end of season four. (Not a Da Vinci Code crossover, BTW!)

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.

Sequels and side-stories (and more) can be found here Offprint and AO3, and a hardbound two-volume set of all that can be ordered from The Ministry of Image.

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.

Everypony has a past. It might be nice and calm or it might be full of adventure. Alex here has more than just an Adventure. He has to deal with Ancient Precursors and Power Hungry corrupts. Join him in the fight and in the end, he finds true love. You will see much betrayal both past and some in the present. Like everypony, they all have a secret they hide. This one secret is finally reviled; the dark past. Special Thanks too @Alicemadnessss (Alice), @mlp_Skies (Skies) EDIT-{before bat version}), @heart_autumn (Autumn), @mlp__BlazeFury (Blaze), and @Mlp_Sketchie (Sketchie Pallet). They were in the story and are great friends to have. I'm truly honored to have meet them. EDITOR NOTES- If their is anything wrong or any-other comments you have about the FanFic, please let me know. Thanks And Happy Reading. (Update) - So I see that this story had not gotten very many views and that's alright, we all try new things and sometimes it works and sometimes it just doesn't. I'll still have fights and stuff but i'll try to stay away from not possible stuff. xD I was just experimenting and seeing how things work.

Rainbow Dash would always be there for Twilight, even when her other friends are not. Something is not right in Ponyville. Since her coronation as an Alicorn Princess, Twilight has been blamed for things she clearly didn't do, and everypony but Rainbow, Scootaloo, and Spike have disowned her. However, this is not just an emotional struggle. With the Elements in disarray, all of Equestria is in danger as an old enemy returns...

Contains: TwiDash, Scootadopt, Gore, Violence

Thanks to Surry, LightningBass94, and twidashforever. Without them, this story wouldn't have been possible.

Partially inspired by the story The Truth in Meanings by Twidashforever

Schnitzel hated his lot in life, but carried on every day, knowing tomorrow could always be better, provided Chowder didn't eat all the food again or set the kitchen on fire.

Then he woke up in a magical place after accidentally inhaling too much Pizazz.

(I loved this show, by the way. Also, I know the way he's spelled in the picture is different from how I've spelled it, but come on; his name is based on a real food.)

I was known as Frank DeFontaine. I was going to a Halloween party. I was a pretty intelligent kid, starting my first college term, and decided a little dress-up couldn't hurt.
My buddy Richard got involved, though. And like everything, he took it a bit too far. This time, I didn't say no, though. I really should have.
Next thing I know, we're going all-out on making my Dullahan costume. Because he's my favorite optional boss, and all.
Really shoulda known something was up when that guy behind the counter just so happened to have a sword that fit our specifications perfectly.
Next thing I know, I'm in Equestria. And I'm missing a head.
Sakes, I could use a drink. And a neck.

I'd like to leave it at "Holy mother of-!" but that doesn't capture what I'm feeling!

Distance can drive us apart. It can also bring us closer together.

After all is said and done, and the ponies have gone their separate ways, the only way they have to keep in touch is through letters.

If you came to hear a story, I’m sorry to disappoint. I suspect this’ll just end up as one big confession, really. When you’re the first Teutscher to set hoof into Equestria, I suppose that’s to be expected. And when you’re the universe’s favorite chew toy, doubly so. Still, with enough wit, some Prussian ingenuity, a droll sense of humor, and wanton murder, I might just survive this. Then again, when you’re going up against an unending list of things like government conspiracies, that guardian angel who keeps telling you to kill ponies, psycho Equestrian girls with allophilia, a lunatic princess, the legions of the Inferno, the Equestrian culture itself, swashbuckling sword fights, and laissez-faire economists, you begin to realize why there’s a big “if” in the middle of your life.

Your thoughts/critiques/deathreats are welcome in the comments. Spoilers are also encouraged. If you don’t have anything to complain about, do please tell me what you liked so I know what worked.

Now on TV Tropes. Posted on the Equestria Daily 5/28/13. Now in ePub format for your convenience.

When a meeting with a corrupted being causes Princess Celestia to change into something…chaotic. Princess Luna must find a cure while Celestia battles her hidden inner demons.

Will Luna and her friends find a way to cleanse this evil or will Equestria see the creation of it’s greatest villain?
