On Equestria-320, all the ponies have superpowers be them big or small, but only those who choose to display them are on the league. It's a whole 'nother world of paradise where everypony gets along for the most part as they are all united by their superpowers with the few stand outs who feel they should be the ones in control even though they're all the same. There are still normal ponies too, but since they're so out numbered they are forced to hide in the shadows and in cafes that the superponies don't even know exist.

One day, just like that, Celestia decides she's going to go mad with power.

This story is a sequel to The Cadenza Prophecies

Princess Flurry Heart inherited her mother's beauty and grace as well as her father's strength and bravery. The Empire couldn't hope for a better or more suitable heir to the Crystal Throne. Everypony in Equestria admires her and thinks she will be an ideal ruler.

They're wrong.

Young Flurry Heart has no interest at all in being a prim and proper princess, and would much rather have wild and dangerous adventures like her Aunt Twilight.

Book 5 of the Alicorn Adventure series.

Shining Armor and Princess Cadance celebrate the birth of their first child, blissfully unaware that her arrival fulfills a dark, ancient, malevolent prophesy of doom. Calamitous events set into motion by Flurry Heart’s birth tear apart reality. The ground is torn asunder as sinister invaders emerge from the underworld. Ancient cults emerge from the shadows to herald the foretold arrival of their dark overlord. The Crystal Empire faces its most dire threat yet as a new, evil, and most adorable master launches her campaign to lay claim to the world to bring about a new era of unsurpassed evil.

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.

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.

When they are forced to kill a dragon attacks the Western Watchtower in the Whiterun hold. One of the six will soon discover that they are the legendary dragonborn, meant to defeat the World-Eater.
