When one of Twilight's spells goes horribly wrong, the implications prove disastrous. Her horn is damaged, one of her friends is sorely affected, and the rest of Ponyville may be at great risk. It's now up to Twilight to figure out how to fix everything before it's too late.

As proud as she was of her royal duties, the nights in Canterlot often left Luna bored and lonely - remembering her troubled past as Night Mare Moon made it no easier. Determined to clear her head, the Princess of the Night decides to take a night-time stroll - making new friends and discovering things about herself in the process.

Twilight finds herself enthralled by Princess Luna and everything she represents. As Celestia's pride and joy, Twilight struggles to repress these feelings. But an old and well-known evil surfaces again at the worst time. Can Twilight fight off the spectres of the past?
