Humans have figured out intergalactic flight, or think they have. With the successful experimentation of miniature prototypes of the hyper-warp drive, a larger version is made.
One man, James Mane, has both the knowledge of how the systems work and the physique to pull off space travel. No-one else was brave enough to volunteer, so he stepped up and took the role.

The story begins with him at the launch pad ready to take flight in the Celestia One - the pioneer ship to test out this device.

However, something goes wrong during the long journey... He found Equestria.
