Twilight wasn't the only one with a brother no one knew of. It turns out that Rainbow Dash's twin brother -the very brother she hasn't seen in six years- has come to Equestria.
Hailing from the proud country of Cervidas -a country in the eastern continent of the world across eternity's crossing- Rainbow's brother Gabriel has become a well known performer, a DJ who studied the art under Vinyl Scratch, one of the music world's greatest legends, also known by her stage name as PON-3. He has come with his best friend -tooth II- on a work visa to work with his record label and takes residence in the booming city of PonyVille. There, he finds his sister and meets all of her friends. Finally together again they can hopefully pick up where they left off in Cervidas.
