Luna has gone on a vacation with Tia for the week. But every night, she slips away from her sleeping sister and guides her hooves to a snowy area. But tonight…. Tonight seems like something more. Not just a snowy land where she battles her guilt over Nightmare. As she turns, a dark gray stallion stands before her…. A red tint on his horn, and purple smoke misting from his eyes….. And it seems they have more in common than they thought.
