Manehattan is one of Equestria's most modern cities. A classic city of modern innovation, as it were. Even when a convention showcasing some of Equestria's most innovative pony inventors, striving for a new tomorrow, not much seemingly changes on the surface.
When a young unicorn inventor by the name of Light Sparks comes to the convention, he soon learns that when the future and getting results is all anypony can think about, moral value tends to go down on the scale. Striving to make the world a better place, Light Sparks ends up going on a small, indoor andventure of math and science.
The convention may only be a week long, but the outcome of what could happen may change Equestria forever, or, at least Manehattan.
