After reading Rainbow Factory Condemned, by LordCarn, I felt that the ending wasn't sufficient enough, so here is my extra bit that I felt was needed to do the ending some justice.

This is ultimately my own creation, although it picks of where RFC left off and is a much happier ending than the original. I do not intend to carry this on in second person as it would ruin the whole perspective of the story.

So I give to you, the people of FIMFiction, my ending to Rainbow Factory Condemned by LordCarn.

Twilight visits a strange, yet familiar Earth, in which some people are not your regular humans, on the request of Celestia to learn human ways of life and to try and fit in alongside these humans that are similar to her.

This is the story of how she tries to fit in at a school for these different humans, meeting old friends she forgot she had.

For the Achievement Hunters, It was a normal day at the office, but that was all to change when a newbie painted his GTA car like Rainbow Dash. They find themselves in the Equestria Girls Universe with a vampire among them and the Mad King, who's returned for good.
