Earth (Code Geass) - An Equine-Flavoured Conversion

The Hermpire Ring had recently completed its conquest of Equestria, though not without consequence for its own existence.

The pony goddess Celestia had fought her conversion and fought well. It had not been enough but something of her essence had mixed into the ring itself during her attempt to purify it even as it corrupted her.

The titanic struggle sent the Hermpire Ring to its next world with a tidal wave of divine magical power that swept out to encompass the entire planet to twist all of its inhabitants in an instant. Only those with the power of Geass were immune and even then only their minds were protected, their bodies twisted like all the rest.
