In the coldest part of the world, there was a tall mountain that held a secret. Up on the highest peak there was a tower made of ice. This tower had no door to allow entrance, just three windows up at the top. This white, frozen fortress was both to keep people out and to keep a treasure within.
Kozmotis pitchiner, aka Pitch Black, or the Boogieman appeared next to the tower in a large swirl of nightmare sand. He felt the air around him get slightly colder as his treasure realized he was home.
"Jack, Jack, won't you send a ladder of ice, so that I may climb the frozen tower (1)" Pitch called with a dark smirk that only grew as smooth steps made of ice formed from one of the large windows down to him. While he did sort of regret making it so that no one could use any form of magic to enter the tower (even himself) he did so love watching the boys power which had only grown in the last 300 years.
He graceful began to rise up the steps and when he reached the top he stepped through the large window only to have a chilled body slam into him.
"Welcome home Papa." The boy spoke, his voice gentle but with a hint of the icy winds. Pitch looked down, almost fondly at the mop of white hair.
"Hello, Jack, have you behaved yourself?" Pitch asked when bright, ice blue eyes looked up at him from pale face.
"Of course Papa! I made sure to keep the place clean, and read all the assigned books!" The boy proclaimed with a grin.
"I never doubted you. But I needed to tell you that I would be gone for the next week." The boy's eyes dimmed. "I know you don't like me being gone for so long but I do not have a choice. You understand?"
"Yes Papa."
"That's my boy, tell you what to make it up to you I will bring back those special paints from the far sea that you love to use."
"Really! Oh Papa thank you!" The boy hugged Pitch tight before spinning away from him and jumping up and down in joy.
"Yes, yes, now I must be going but behave yourself ok."
"Yes Papa"
Pitch placed a kiss to the boy's brow before stepping out onto the frozen steps witch disappeared slowly behind him.
Once he was gone the 16 year old boy lifted the lid off of a pot and a colorful blur came flying out, squeaking at him.
"Yes, yes I know baby tooth." More squeaking. "I know he's not a good person but he's all that I have ever know."
Jack Frost sighed as he settled onto his frosty couch looking about the frozen room. It was covered in colorful, painted canvases, and hundreds of books. It had been his home for the last 300 years.
Jack remembered waking up on a lake with no memories of anything beforehand. He had heard a name which he had taken to be his own. He had had a lot of fun with the staff which made ice, and the wind which made him fly. But then he had entered the human town and found that no one could see him. Except for Pitch.
Pitch had come to him, as he shivered from the cold feeling the walk through had caused. He had told Jack that he was a friend and could help him. Jack, naive and lonely followed Pitch to this icy tower away from everything. Once there Jack had found he could not leave again. His powers weakened and his staff taken away, he was stuck in the tower, not able to stick a hand out the window for the magic barrier that would burn him. The most he could do was create frozen stairs along the tower so that Pitch could come up to him. For while Jack could not exit, no one else could enter with any form of magic but Jack's stairs.
Jack had found out very quickly that Pitch was a bad man. He gave Jack nightmares, and purposely frightened him. He used Jack's terror to siphon power off of him. After 50 years of terror Jack had given in and stopped trying to escape. He called the man Papa, as the man had asked him to. He was a good boy. He acted like a child, keeping the man happy. Now he only got physically hurt when the man was in a foul mood. Otherwise he only had to deal with the nightmares and weakened power
After 200 years in captivity he had been found by baby tooth. The little tooth fairy had been flying by when she saw the tower. A curious little fairy she had flown though the window and found Jack. When Jack discovered he could understand her he was so happy. Baby Tooth, as Jack had dubbed her, became smitten by Jack. She soon claimed the eternal teen as her younger brother, her charge and refused to leave him. Other fairies had been sent to the area that she had disappeared but no could find the fairy. And 100 years later she had been as good as forgotten. Which was perfectly fine with baby Tooth, because Jack needed her in a way her mother and sisters did not. And so when Pitch returned home Baby Tooth hid, and when he left she spent time with Jack, telling him of the world.
And now that they had a week free they hoped to see if they could achieve their escape.
So this is basically a horrible rendition of the Rapunzel quote "Rapunzel, Rapunzel let your hair down, so that I may climb the golden stair" yes I know it is a horrible edit but I had trouble figuring anything else out.
