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 Stardust

Everyone knows the story of Hearths Warming Eve. They know the tales of the three pony tribes and how their strife brought the Windigoes upon them, and how the Fires of Friendship saved them from their frozen fates. For countless generations the tale has been told, but how has it changed over those years?

Or is any of it true in the first place?

Only one pony knows, and Celestia would prefer that the past stay forgotten.

(Based on a 'What If' line of thought that was born from the Stardust storyline. While some familiarity with Stardust and Mente Materia doesn't hurt, this story can be enjoyed on its own)
(Coverart available soon from the amazing FoxInShadow!)
(Many thanks to Arzoo, BradTheBrony, Vandenbz, and Setokaiva for prereading!)
(Complete with it's own TVTropes page as part of the Stardust continuity)
(Character tags will be added as chapters are added!)
(Possible spoilers in the comments! BEWARE!)

This story is a sequel to My Little Alicorn

After the events of "My Little Alicorn," everything seemed to be back to normal...except for one pony. Prince Blueblood is now trapped as a colt, his title, possessions and birthright stripped for his crimes. Before Princess Celestia will return him to normal, however, he must prove himself by attending Magic Kindergarten. Even worse, his current situation has attracted the vengeful gaze of two ponies he has offended in the past: the Captain of the Royal Guard and the Moon Princess.

Will Blueblood rise above his past self and emerge a better pony? Or will he sink back into his old depravity, and be stuck a colt for the long term?

Note: This is a sequel to "My Little Alicorn," so you might want to check that out first.

Twilight has finally returned home from the harrowing challenge that Discord set upon her, and the residents of Ponyville and the Elements especially look forward to having their dear friend returned to them.

Twilight, however, has changed. Still suffering from her injuries, almost incapable of using magic and haunted by the memories of her time on Earth, she becomes increasingly withdrawn from those who were closest to her. Will her frustration at her current state and her friends inability to understand her experiences cost her what she valued most before Discord's bet?

This story is a sequel to No Heroes Part II - The Journey Home

In No Heroes Book II, Lightning returned to the orphanage that raised her only to watch it – and all the children she loved – burn to ashes. Yet the tragedy wasn't a total loss: she was able to rescue one filly. Burdened by failure, Lightning decides to take tiny Keen Arrow into her care.

Lightning has never considered what it might take to raise a child. Has she rushed into another task too big for her wings? Now she's in a position she never would have imagined, and Lightning must make a choice between her dreams of glory and her new responsibilities.

But is Keen willing to wait for her to figure things out?

This story expands upon the events established in No Heroes. Although reading the series will help in understanding the background material, it is not essential to enjoying the content of this story.
