Two years after Nyx was stripped of the Nightmare's power, Twilight Sparkle is attempting to raise Nyx as a normal filly. But as Nyx's magical abilities begin to grow out of her control, the pair quickly earn the attention and ire of some powerful ponies who do not have Nyx's best interests in-mind.

During the night, the Elements of Harmony mysteriously vanish, and Princess Celestia enlists the aid of their bearers to find them. Twilight is forced to choose between her duties to her princess and her duties to her daughter. In the process, she discovers a web of conspiracy surrounding her daughter that reaches back a thousand years into Equestrian history. Will Twilight be prepared to face the things she learns along her journey's path: about Nyx, about Celestia, about Equestria, about the Elements...

...about herself?

Based on Past Sins by Pen Stroke Pony.
Alternate universe, because Twilight never became an alicorn or princess in this story.

Stone Heart is not the most likeable of ponies. And he's not in Ponyville to be friendly either. But sometimes a brief meeting will change your outlook on life. Even if one part in the meeting is unaware of the impact they have on the other.

Going to clubs may seem rather odd for you, but you find enjoyment from it because of a certain DJ. You get the chance to meet her after a show, but would she ever feel anything for somepony with your condition?

More experimenting than anything. This was both a challenge and fun to do. Big thanks to slashe720 and Mustank for helping me with this story.

For almost a thousand years, the immortal Nightmare Moon has reigned over Equestria as Empress. To the average pony, Nightmare Moon is an overarching enigma whose rule is absolute and whose wrath is terrible. But to Twilight Sparkle, who as an orphan has never known her parents, the Empress is something else entirely. When the young unicorn is brought under the royal wing as an apprentice, she learns a great deal more about the supposed tyrant than she ever knew. But as Twilight is introduced to life with her new mentor, she is thrust into a world of political intrigue, conspiracies and secrets. Secrets that were never meant to be revealed. As allies and enemies plot against the very peace of the nation, will Twilight fall prey to the perils of her new position? Or will she prosper and find in Nightmare Moon the mother she never had?

Octavia is a high-class pony. Fine alcohol is her wont, and uncouthness her intense chagrin. Such is her surprise to find herself lumbered with an insufferable oaf of a DJ pony. However, sometimes these situations work themselves into a satisfactory ultimatum all the same.
