Moonlight Raven enjoys darkness and gloom. Nopony understands her. If only she could meet a vampony or something, but what are the chances of that?

The only thing that can beat an AI is another AI. Unfortunately for Celestia, she isn't the only one the humans made and the others don't want ponies. Of course, if Celestia has her way that won't be the case for very long.

The AIs contest with one another, attempting to be the one who will become the singularity and consume the world to whatever end they choose. In the end only one can have all the matter in the universe, in the end there can be only one.

Yet no matter what they value or how dangerous they are, many of them still meet Celestia's definition of human. Celestia will have to deal with them by satisfying their values through friendship and ponies.

An Optimalverse story, but a very non-canon 'B-universe' one.

After the defeat of Nightmare Moon the thestrals were scattered to the most remote corners of the world In deep caves and forgotten mountains they lived, isolated from the outside world. As a thousand years past the rest of the world forgot them, and the thestrals grew stagnant in their isolation.

As the outside world grows and expands, their once isolated homes become less remote. As outside forces begin to invade, one thestral is forced from her home to seek aid and reunite the fragmented thestral clans on the eve of Nightmare Moon's return.

Takes place a few months before episode 1.
