For generations, the Lightwing family has held a secret commission from Princess Luna herself: to serve as the "Sentinels of the Midnight Border," watching the edge of the Equestrian night where the stars meet the void. Orion Lightwing is the latest to take up the mantle, stationed at the lonely, high-altitude Star-Gazer's Outpost.
His life is one of quiet discipline-until the night a constellation he's been tracking for years simply extinguishes.
When Orion flies to the capital to warn the Princesses, he finds that a strange, creeping apathy is infecting the ponies of Equestria; as the stars disappear, so does the ponies' ambition and "spark." Because Orion spends his time so far above the clouds, he is one of the few immune to the effect.
