This is a roleplay that my friend and I are working on. This is just for fun.
Years passed after the Guardians of Childhood defeated Pitch and his wild Nightmares, bringing their unique values to life in the world and restoring the balance of Light and Darkness. Aided by the Believers, children with unwavering faith in the Guardians, they were quick to act on any rumors regarding the return of the King of Darkness. Time passed still, and nothing was heard.
Slowly, the children of the Earth would have nightmares. Shadows would hold substance, and humans would go missing in the middle of the night. The Man in the Moon no doubt knew that Pitch was behind the disappearances... Fearing that the Destroyer of Dreams would go to such lengths to build an army once again, he ordered the Guardians to search for the fragments of a blade that once trapped the horrid shade. He explained to the Guardians that an old friend of his, known as Nightlight, had in the past kept Pitch Black sealed away with a dagger infused with his light. He revealed that Jack was a reincarnation of Nightlight, and is indeed one of the reasons why he was chosen to be a part of the Guardians of Childhood.
"If you reforge the blade with the fragments and your frost, it will be able to hold its purpose." the stout man had said to Jack. "That way, we do not lose a treasured friend to time once again."
As the Guardians collected the fragments, they were met with old and new Nightmare minions of Pitch. The shade knew not what the Guardians' plan was, but anything to do with that forsaken dagger was worth stopping or preventing. Unfortunately for Pitch Black, they were successful and forged the blade into a dagger of stardust and ice. After a lengthy battle, Pitch Black was sealed into the blade, the process crystallizing it in a black opaque crystal. It is said that the Man in the Moon took it with him to the Moon, where it is kept in a moonlit room and away from prying eyes. Never again would the King of Darkness prey upon the humans and Children of the Earth…
