Twilight had been living as a program in a college guy's computer, but now she's back in Equestria! Unfortunately, she's still a program, only now she's stuck inside a robot pony. No one's happy about this. ("Pony.exe"/"The Iron Horse" Crossover!)
As a result of a magical mishap in the name of protecting Equestria, the princesses fuse into a single being. But in order to bring them back, she will have to stop existing. What does it mean to die?
Sunset Shimmer returns to reclaim her place as Celestia's student, how you ask? by Stealing Twilight's body! only... things don't exactly go as planned.
