Serving under Luna, much like Shining Armor had for Celestia, Bright Heart works day and night to serve his princess and keep the night safe leading the Night Guard. And taking more than the pleasure of work, he feels affection towards the lunar alicorn, but knows better than to act upon it. But one encounter with a seemingly insane stallion leaves the captain shaken and disturbed, his dreams slowly becoming…darker and leaving him unstable.
