When Celestia was just about to banish Nightmare Moon, a being far more ancient than Equestria reawakens. Calling himself by the name of Naturus, he seizes control over the throne of Equestria that Celestia and Luna held for only a few months and killed them both without letting them beg for mercy.

Now, the ponies and other races had to cope with the world's new ruler and his whims, and the new ecosystem. One thousand years later, oh who am I kidding, I'm not gonna spoil it.

This is the Supreme Naturuverse Saga: a re-imagining of the Rise of Lord Naturus.

Note: I'm not sure if I should add OCs on the MLP spectrum or not, so I'm adding 'other' in case I'm in either mood.
Note: I've heard about the plot reveal for Shadow Play, so what can stop me from adding Starswirl?
