From the description:
Set in the Optimalverse, a middle-aged woman enamored of ‘Equestria Online’ confronts what permanent emigration to Equestria — uploading to a virtual existence — really means… but can she even hope to truly understand such a thing — and more importantly, can she trust the artificial intelligence known as ‘Celestia’?
If you’re unfamiliar with the film, it’s about an intelligent computer that takes over the world. If you’re familiar with the artist’s other work, this won’t surprise you a bit.
