There are four people. They live they're lives as normal people, except no one ever sees them. Who are they? They're the children of evil. They're Pitch Black's kids. No one knows that Pitch has children, not even the Guardians. And the kids don't know that people can't see them. They're cooped up in Pitch's lair all day, only let out at night for the eldest kids to help Pitch bring nightmares. Pitch absolutely loves his children. They're probably almost the only people he cares for. He would never hurt their feelings, letting them know that the Guardians hate him. One night, while the children were playing in a nearby forest at night, the youngest, aged 15, sees a man with white hair sitting in a tree. Its Jack Frost. Jack thinks they're just regular teenagers playing around. " Hi" The youngest says. Jack is surprised. Soon, the children and the Guardians become good friends.

Pitch has been going crazy, looking for his children who have been with the Guardians all along. He plans his revenge. His nightmares will be attacking soon, are the Guardians ready? Meanwhile, the most of the Guardians have grown rather fond of the children. Some have even fallen in love with a child. When Pitch attacks, will they still feel the same for the children?
