Even the most famous supermodel in Equestria needs some time off, and Fleur de Lis is that supermodel. She takes a vacation to recharge her batteries, but what happens when her sweet tooth rears its head?

A little entry for a contest in a Discord server. Haven't written Fleur yet so I had some fun with this one.
Enjoy!

To save her sister and her faithful student, Celestia herself must travel into the ancient tunnels beneath the ruined castle in the Everfree Forest. She, and the guards who accompany her, must face the dark, twisting corridors. Still, what was Luna and Twilight's purpose at the old castle? Why were they unable to return of their own accord?

And what watches Celestia from beyond the light's edge?

This story is a sequel to Into The Depths

The horrors of the catacombs have turned to distant memories for Celestia, Twilight, and Luna. Discord’s change of heart and Twilight’s coronation have helped to ease and erase the mental scars from that harrowing night. The three princesses can even smile and laugh as Nightmare Night moves into full swing.

Yet, it should never be forgotten that those who have been touched by Tirek are forever within his grasp.

Rainbow Dash isn't your ordinary pegasus. She has a secret ability that ponies thought only unicorns and alicorns could posses. Magic! Not magic like Twilight's though, Rainbow's is stronger. And it's dark magic.

Sorry I suck at descriptions

So I had a weird dream where I saw Rainbow Dash ruling the Crystal Empire like Sombra did and thought, "Hey would it make a cool story if Rainbow Dash was secretly King Sombra's daughter and had a stronger version of his abilities?" So here it is! Not too harsh in the comments please, this is just an experimental story to see where it goes. Helpful advice is always welcome though!

Daybreaker: the monster in Celestia's heart, and the age-long mystery of her life. Her friend and tormentor, her companion and foe. Fanatically devoted to their future, yet desiring one horrific to Celestia.

It is growing stronger.

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.
