A mysterious machine is discovered in the cellar of Canterlot Palace. Taking it back to Ponyville to study it, Twilight Sparkle learns that the machine is called a "supercomputer", and contains a mysterious virtual world--and a virtual mare who can't remember who she is. Even as Twilight and her friends learn they can enter the virtual world, something else that lives in that world awakens, and begins to attack the citizens of Ponyville...

Most changelings only want to feed on love and serve their queen, defending her with their lives. But Scales the changeling has never seen eye-to-eye with the others. All he wanted to do was cook. He leaves the hive and finds himself in Ponyville as a baker. He finds peace, but will that peace stay?

((Being rewritten starting from chapter twelve))

Twilight and the other Elements of Harmony have saved the land of Equestria from Nightmare Moon, Discord, and the Changeling army, but now they face perhaps their biggest challenge yet. A challenge that lurks behind smiling faces and friendly eyes. A challenge that threatens to overtake the entirety of Equestria and enslave its inhabitants. But the ponies won’t face this threat alone. Help comes in the form of the most unlikely of companions: four teenagers, a hawk, and a blue centaur.

When Ruby boards the first trans-oceanic flight in Equestrian history, the last place she expects to end up is stranded in the middle of Eternity's Crossing in the wake of a horrific zeppelin crash. After a mysterious tower leads her and a fellow survivor to discover a twisted and fragmented city twenty thousand feet below the surface of the ocean, though, a bit of fire and smoke is the last thing she needs to worry about. Between the horrendously disfigured residents and the paranoia of the madmare who once built and controlled it, daily survival in this corrupted utopia is anything but a guarantee. But with the help of some new friends and a few genetic enhancements, Ruby isn't going down without a fight, and in the process might just discover that the deadliest weapon in Harmony is herself.
