Nyx is a reclusive unicorn who has come to the fair Canterlot to complete a contract. Usually he would prefer to avoid getting his hooves dirty with manual labor but this job is too sensitive and important for him to trust anyone but himself in its completion. But now that he has arrived at Canterlot Nyx realizes things won't be so easy as to simply sneak into the Royal Castle while the whole city prepares for the marriage of its own Shining Armor and Princess Mi Amore Cadenza.
