The Mane Six have lived peacefully for a month since the wedding of Shining Armour and Princess Cadence. Things would not stay peaceful, for the six are whisked away back to Canterlot. Discord has gone missing from his cell and the group discover a particular pony who will need all of their help.

Uriel just wishes to return home but is denied by Discord. His only hope is the Ponies of Equestria and the fleeting dream of his own planet still in his heart. Challenges will test him as he falters under the pressure of sudden titles and implications. He can only rely on those who truly care for him.
