This story is a sequel to The Assembled Letters of Twilight Sparkle, Protégé of Emperor Discord

After getting a taste of Friendship and questioning her allegiance to Discord, Twilight Sparkle chose instead to accept the will of Chaos and remain a student of the Emperor. Now, she has been charged to return to Ponyville and plant Seeds of Discord around the Tree of Harmony, but there are more things than broken friendships awaiting her arrival in Ponyville.

A note on the [Dark] tag: This fic is not grimdark.

It is however, an adventure story with high stakes, and themes that may touch on more serious matters, such as brainwashing or mental/emotional abuse. There is also some brief moments of violence and intense danger that, while not excessive, may be troubling to some. This tag was actually something recommended by one reader after Discord's psychological games with Twilight in the previous story, and I think it's time to add it. Link to reddit discussion where I made the decision, slight spoilers for Chapter 6.

Please don't let it turn you off from the story, just consider it fair warning that some parts may be slightly disturbing to more sensitive readers.

Ponyville's new 'code enforcement professional' has got it into her thick, monotonous head that Fluttershy has too great a density of pet animals, and she's set out to rectify that situation.

Twilight, though, has a problem with this, and she'll have to use her full authority as an alicorn princess to put a stop to it.

These are not these stories.
These are the stories from the inside. The stories that make a makeshift family work. The small moments. The little secrets. The normal life.

Short stories about Twilight's and Spike's life before the events of the Lunar Guardsman. Maybe a little funny, maybe a little sad, maybe a little sappy, certainly not on any chronological order. Chapters posted whenever I am taken by the mood to write one.

This is a collection of prequel stories to The Lunar Guardsman, an M rated story currently in progress by yours truly.

Many of the chapters are worthy of the Comedy tag, some of the Sad tag, and a couple of the Dark tag.

A story in the same vein as My Little Dashie, but not a carbon copy.
Awoken in the middle of the night by a mythical creature sitting on his doorstep, a man's life is drastically re-arranged by the sudden entrance of Princess Celestia. Struggling to accept things he couldn't ever think possible, he'll have to make a decision about what's worth changing his entire life.
(Note: I added the "Alternate Universe" tag because I imagined this being a reversed-roles universe where Luna is the big sister and banishes Celestia, rather than the other way around.)
