After finding real friends for the first time in a strange dimension of odd creatures, Sunset Shimmer has finally decided to return home to Equestria in the hopes of apologizing to Princess Celestia for her betrayal. Instead, she is greeted by an attack from the Royal Guard, and a pursuit across nighttime Canterlot that ends in disaster.

Can two injured ponies who hate each other so much manage to survive the Everfree Forest and return to civilization, or are they just doomed to be eaten?

Orphaned as a filly, a young pegasus named Kaviyayu is raised by an adoptive Earth pony family in a secluded, peaceful village. When a strange unicorn drops by the village, Kaviyayu and the other foals are captivated by her tales of the world, as well as her various spells and illusions for their amusement. But there's something about the way she doesn't speak of her own family... how she never removes her traveller's cloak... how she seems to take a very strong interest in Kaviyayu...

Who is this mysterious mare, what does she seek, and just what is so special about that pendant she wears?

This is the tale of how a seemingly ordinary filly rose to become both a princess and a beacon of love to ponies all over Equestria. Based on the back-story of Princess Cadance, as given by G. M. Berrow's pony novella, Twilight Sparkle and the Crystal Heart Spell. Also loosely inspired by symphonic metal band Nightwish's sixth studio album, Dark Passion Play.

Cover art by the lovely Ayemel.

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: Goddess of the Sun, ruler of Equestria, beloved Princess of ponies. She is loved by all, and loves all in return. A calm and wise ruler, she sits on the throne in Canterlot, maintaining peace and harmony throughout the land.

What most don't know is that her past is much darker: She was once a commander of legions, a warrior and scientist of unmatched skill. Thousands of monsters and abominations fell to her forces, slain in the name of an old leader, one entombed within his own throne. Free of her old form, free of the powers of Chaos, she was cast into a new realm, in a new form, with a new lease on life.

She is the God Emperor, Eternal Ruler of Equestria and Lord of the Imperium of Man.

Big Mac is an ordinary country boy. Even though his little sister gained magical super powers, he's managed to stay out of most of the weirdness. But things go pear-shaped after he starts spending more time with his physics teacher, Dr. Discord. Thanks to Dr. Discord's time machine, Big Mac becomes stranded in the year 1993, and that's not even the strangest part.

No, the strangest part is that his mom keeps flirting with him.

This story is a sequel to Will of The Shadow Monarch

Following the birth of Flurry Heart and the acquisition of King Sombra's journal, Twilight Sparkle sets out on a new quest to bring the insane king's followers to justice. Her quest leads her and Fluttershy to the very edge of Equestria, to the mythical forest known as "the Ulvenweald", a place filled with deadly beasts and vegetation alike.

Can a bookworm like Twilight and a pegasus with crippling anxiety like Fluttershy overcome such a place and hunt down the mad king's loyalist? Or are they, in fact, not the hunters but the prey?

This story is a free-standing continuation of my story: Will of the Shadow Monarch. Reading that story is recommended, but not at all necessary.

This story will contain words and images. If you are allergic to such things you might want to find another story. The pictures come from Magic the Gathering and are repurposed to fit with what is written.

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.

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.
