Thunder Lane was a good Palace guard. A fine guard indeed. But when an incident occurs that causes him to question the very bodily fibres of his good friend and companion Doctor Whooves, drastic changes are brought about.

Doctor Whooves has a secret. A very deep secret. A secret which, if it fell into the wrong hooves, could cause the holder to be Supreme Ruler of Equestria.

Perhaps the world.

What occurs when the secret is divulged unto Thunder Lane, the Pegasus? Will his mind be corrupted, or will it be used for the good of all?
