On the surface, Lightning is a seemingly normal, young Pegasus-mare type of pony . She's got a decent job and is moving fast on her job as a weather mare. But an intense, paralyzing fear that has been terrifying her since childhood is tearing her apart. And it's getting worse every day. When Lightning was a filly, something devastating happened. Each night her dad would put her to sleep with a bedtime story. Many of these stories teetered on the brink of horror, much to her mom's chagrin, but Lightning and her father made sure her bedroom was safe when the lights finally went out. Until that one fateful night. When Lightning is forced to move outside her comfort zone on a spring trip to Ponyville to visit her cousin Applejack, she leaves this protected world and things begin to fall apart.
