When King Sombra was still ruling over the Crystal Empire, he decided to restrain his illegitimate son deep inside his black castle.
Sombra feared that his son would overthrow him one day and bring the downfall of his bountiful empire.
The imprisonment was maintained for almost twenty years, until two powerful Princesses defeated the evil King and set his son into a millennial slumber, waiting for the right time to come.
A thousand years later, it is up to the recently crowned Princess Twilight Sparkle to teach King Sombra's pegasus son the magic of friendship. But will he accept the lessons Twilight has to offer him?
