Luna, the protector of the Everfree Forest, was idealistic in her youth, assuming that the strange creatures and the ponies would make peace with each other. She befriended a handsome stallion, but as they grew older, his ambition would change his heart for the worse. When he stole her wings, she transformed into Nightmare Moon, and sought revenge on those outside the Everfree.

The same princess Nightmare Moon had cursed would steal her heart. Would she know what true love was, or would she remain evil forever?
