This story is a sequel to Dexter's Lab: Equestria

He was so sure Nightmare Moon wasn't real. He was so sure all the stories about Nightmare Moon were merely fabrications meant to induce fear in the ponies of Equestria, and insure their loyalty to the alicorns upon the throne. In fact, he was so sure Nightmare Moon didn't exist, he built a time machine to go back 1000 years and prove it.

Needless to say, this time-travelling colt genius bit off more than he could chew.

Now the 8-yr-old must survive the chaos of Nightmare Moon's uprising, forging unexpected alliances while learning to trust in the word of others. But unfortunately for him, Nightmare Moon isn't the only surprise in store for this colt.

This fic is a side-story to Dexter's Lab: Equestria. As requested by you readers, this story will be expand upon darker themes surrounding Luna's original descent into Nightmare Moon and the following events. - But expect a twist or two. This story was made separate to Dexter's Lab: Equestria because of it's darker themes and atmosphere. Reading of Dexter's Lab: Equestria (to chapter 11) is not required to enjoy this story, however it is strongly recommended as it will explain a lot (especially if you've never seen the Dexter's Lab TV show.)

Princess Celestia and Princess Luna are leading together a combined Army of several different equestrian Races against an supposedly terrifying and unfeeling Enemy.

What kind of Threat are our beloved Princesses are really going to face?

"These papers are my reports upon my studies of equestrian cutlure, physics, genetics, magical theory, geology, politics, and war. Viewed in as scientific form as I can manage.

These are my theories and observations as best as I can describe them, and their contrast with those in my home reality. Hopefully, these observations will shed further light upon the world of Equestria for those within, and should these ever manage to go further, those without."

(Inspired by both Xenophillia and The Xenophillias Guide to Equestria, two very awesome stories.)

This is directly connected to my other story, Consequences of Unoriginallity, and are in-character observations of the main character. These observations do not occur at any specified point in the story, and as such, may have slight spoilers. Reading of one does not require reading of the other.

Supreme Overlord of the Dominion of Equestria.
Wonderful title isn't it?
Capture the Country, Marry the Princess, Take over the world.
Sounds like an Adventure story doesn't it?
Well this is no story.
How do I know? Well I'm not stupid for one.
All those other dolts that came before fell into too many simple traps.
They're all so easy to avoid.
That's why I work to rule.
The rules.

This story is a sequel to Dear Princess Sunbutt

When Anon takes the liberty to inject his particular brand of humor into Twilight's friendship lessons, Celestia feels the need to respond, more often than not.

A somewhat unofficial sisterfic to 2Merr's Dear Princess Sunbutt

There may not be a response to every letter, and letters 1-11 were taken from my comments in said sister-story.

Please support 2Merr's story too if you like this one. This is written with encouragement of the original author.

EDIT: Apparently someone's done a reading of this and its sisterfic over on Youtube! Why does nopony tell me these things.

Anon takes over Spike’s job of transcribing Twilight’s friendship reports. He does exactly what you’d expect.
