This started as me writing a simple explanation of my headcanon for how the planet Equestria is on works and how it came to be that way and then it got away from me a little bit. Maybe more than a little bit.

Yes, I'm naming the overall planet Terramundus. Yes, that's two Latin words for "Earth" smushed together. It felt wrong to me personally to have a pony-centric name for a planet that's been shown to have more than just ponies on it.

I don't remember if the Human tag needs to be added for anything involving humans or if it's specifically for not-Equestria-girls humans but I figured better safe than sorry?

For the best experience, read this like it's the voiceover for a space documentary with needlessly dramatic animations.
