One day, Princess Twilight Sparkle came down to her throne room in her sparkly crystal castle and found a young human girl sitting in her throne...who, apparently, is her castle.

Just as Twilight is growing into her role as a Princess, her castle is growing into its role as a Tree of Harmony. And like any child, it needs...guidance.

The only problem: Little Tree is a bit of a brat.

This story is ENTIRELY FoME's fault.

For as long as the oldest of them could remember, the Guardians had defended what remains of humanity against the forces lurking in the dark. With gun, blade and the Traveller's Light, the heroes born of Earth put themselves between the monsters from the void and those too weak to fight back. Human, Awoken, Exo; the physical coil of the Guardian had never truly mattered so long as they were willing and capable of defend their homeworld.

Until a Guardian came from the wastes that was neither Human, Awoken or Exo; a Guardian not born of Earth.

This story is a sequel to Celestia

Villains rarely appear out of thin air. They start as most creatures do, but fall victim to fate, choice, manipulation... or love. Princess Luna's descent into the Nightmare is something that has been long forgotten by modern ponies, but Luna will always remember.

(Sequel to Celestia, and a part of the past that she would rather keep hidden. Reading Celestia is strongly recommended!)

This story is a sequel to Changeling Space Program

Twilight Sparkle's experimental interplanetary drive has malfunctioned, stranding Starlight Glimmer, Spitfire, Cherry Berry, a changeling and a dragon on a hostile planet in another universe. With limited food supplies, very little magic, no communications with home, and no way to leave the planet, they must survive until somepony rescues them.

Fortunately they crashed right next door to another creature with the exact same problem- a creature named Mark Watney.

They're going to science the buck out of everything- and do whatever it takes to survive Mars and get everybody home.

This story is a sequel to The Sisters Doo

Dinky Doo just learned that her mother, Ditzy, is Daring Do's sister. Now, together with the Cutie Mark Crusaders, she sets out to find the Cakes' kidnapped foals. Their adventures teach her more than she expected about crusading, sisterhood, and ― most of all ― herself.

A side-story to "The Sisters Doo".

As the Princess of Canterlot, the Mistress of the Sun, and the most beloved ruler of Equestria, it could be assumed that Princess Celestia was the pony who ran Equestria. Few people know that she actually doesn't.

Her assistant, Raven Inkwell, does. And Equestria would be nothing without her.
