Like the description said, "a universe where the Elements of Harmony never existed if the tree didn't exist either" is where a former human ended up in. Not only that, but they were turned into their sheep OC, Jasper. There, he makes friends with lots of ponies while also having to deal with events that have or haven't happened in the show.

Some of the OCs in my story belongs to those who have their own MLP AU ask blogs on Tumblr. After all, they're the counterparts of those people's OCs.

The "Crossover" tag is there because this story is technically a crossover between multiple MLP AUs since it has counterparts of the characters from those AUs in the story.

The cover title art was drawn on Toyhouse by InvaderAlien.

The Psychopath proofreads this story.

What happens when the world is left for robots to live in? Well, They try to live in it as much as they could. But some one doesn't want that to happen. So what do they do? They send other robots to slaughter them all That's what.

Do you remember your dreams when you sleep? I never did, until recently that is. Now when I go to sleep I awake in a whole new world. As a Pony no less.

Inspired by a manga I read, the name of which I don't remember.

Takes Place right after Twilight becomes an Alicorn so she still has her library.

MC also has no idea about MLP but it does exist in his world, he just never watched it.

It all started with a simple question: What if? What if Luna had ponies who noticed the beautiful nights she created. Would she have turned into Nightmare Moon? Would she and Celestia rule together for a thousand years? Would Twilight meet the rest of the bearers of the elements and become friends with them? Now, with the help of a new magic spell that she created, Twilight is going to find out!

Welcome to the Lunar Republic!

Featured 4/9/15

Almost six years have passed since Celestia's defeat at the hooves of Nightmare Moon. In these six years, Queen Nightmare Moon established Equestria's dominance over its neighbors under her iron hoof.

Just one week before the 6th Nox Eterna Festival, there are still underground insurgent groups opposing her. Among them, there is a terrorist known as "Ghost" who has grown increasingly active in the month leading to the festival.

Dusk Shine, pupil of Her Majesty Nightmare Moon, is assigned to aid the Lunar Inquisition in finding the "Ghost" where they last struck: Ponyville.

SF (canon species only; no humans) Ponies were magically and genetically engineered to be the perfect servitor race. They are powerful, adaptable, intelligent and completely under the control of their creators. A laboratory accident frees one such pony from her mental chains, but how can one mare save herself and the rest of her kind if she doesn't even know she's a slave?
This is not the Equestria you know and these are not your little ponies... not yet, anyway.

This story is a sequel to Days of Wasp and Spider

Believed dead by their creators, the ponies that will become Celestia and Luna have broken their mental conditioning and escaped into the wilderness. Here they plan the revolution that will free all ponykind, knowing that it is only a matter of time before their ruse is discovered.

Back in their underground arcologies, the ponies' erstwhile masters deal with the consequences of the escape, all the while unaware that something lurking at the bottom of space-time wants them all dead.
