Tinker, a young engineer in Ponyville, discovers an otherworldly device which helps him craft a machine that allows all ponies to fly - and without magic! After a decade of development, the newest of these machines allow ponies to fly faster than any Pegasus normally could. Many see the device as a wonderful advancement for ponykind as a whole. There are Pegasi who view such machinery as unnatural, however, and see the sudden influx of Earth Ponies and Unicorns into Cloudsdale as threats to their race. Tensions rise, and it seems as if Cloudsdale is going to secede from Equestria. Tinker must now assist the Bearers of the Elements in defusing the situation. If not, Equestria will be plunged into one of its worst civil wars.
