For centuries and millennia, the Doctor battles his own set of enemies while exploring the universe.

The Master once again is up to no good. The story is usual, right? The hero saves the day and evil is defeated no more no less.

However, the Master is bored. Recently, the Doctor has lived in Equestria, serving as an ally for the Mane Six and their friends. Now it is their reluctant battleground both physically and spiritually.
