A year after Nyx's first Hearth's Warming, she and her adoptive mother Twilight Sparkle are back in Canterlot to visit Twilight's parents... and, as Nyx learns, to take a tour of Celestia's School for Gifted Unicorns on the teacher's workday after school has let out for the holiday.

Unfortunately for Nyx, not all the faculty is as good at teaching as Princess Celestia... or, for that matter, as good at not being a pest.

And why does Superintendent Spell Nexus, the pony who created Nyx with forbidden magic, keep turning up? (Well, besides the fact that he runs the school.)

An unofficial story in the Past Sins universe, set a year after Winter Bells. Written for Brony-wan Kenobi for the 2022 Jinglemas story exchange.

Part of the Remember Fort Libris print anthology, thanks to our Kickstarter supporters!

In the heart of Equestria, shadows gather and secrets lie buried. A young alicorn named Nyx carries the weight of a dark past, while a relentless adversary seeks revenge that could shatter her resolve. As a deadly game of intentions unfolds, alliances will be tested, and the boundaries of morality blurred. Unveil the enigmatic journey where loyalties waver and a sinister peril looms, threatening to unleash chaos upon an unsuspecting land. 'Black Feather' is a tale of mystery, vengeance, and the choices that define heroes and villains.

This is a rewrite of the A Mega Blast from the Past series.

Twilight Sparkle, now the new high Princess of Equestria, has been having a meeting of the Council of Friendship. But since then, things haven't been quite alright. Since Twilight has moved into Canterlot Castle, Nyx (from Past Sins) and Joshua (from New Life in Equestria) have been having a tough time since they transferred from the Ponyville Schoolhouse to a school in Canterlot. But things have been getting a bit complicated when an unknown magical force surrounded all of Equestria and beyond it's border, sending all of the creatures there so an entirely different place, transforming all of them (Except for Joshua) into humanoid versions of their original bodies.

Things might get a bit complicated when one of that world's governments attempt to take over Equestria as part of their own custody, but the only way for them is to get the help of the creatures similar to what they have become, some of which in a group called the Freedom Fighters, being led by the legendary hedgehog, Sonic the Hedgehog.

In the early morning of April 30th, Princess Celestia and Luna came to the peaceful town of Ponyville and delivered a 6 month old filly to live and be raised under the care of the town's librarian and the Bearer of the Element of Magic, Twilight Sparkle. For years, the filly, now named Selena, lived a peaceful life with Twilight, along with her older sister Nyx, while having no clue of her past with the only thing being the strange lightning bolt shaped scar on her forehead that refuses to heal.

5 years later, Selena begins her first year at school, where she befriends the Cutie Mark Crusaders and makes an enemy out of the school bully Diamond Tiara. However, Selena's life turns upside down when Malice Lamar, a unicorn stallion that has ties to her past, escapes from the Canterlot Castle dungeons with a dangerous plot to kill the young filly. In an attempt to protect the young filly, Princess Celestia and Luna move Selena to Canterlot Castle while the Royal Guard begins a pony hunt for Malice.

When things take a sour turn, Selena realizes that the only way to defeat the past is to face the past itself. Will Selena be able to stop the psychotic stallion and save the ponies she loves or will she fail?

In the first chapter to the 'Selena Sparkle Story', Selena comes into the terrifying realization that sometimes, the past can come back to haunt you, but in this case, the past is coming back to hunt her down.
