Chapter 1: Into A Demons Mind

Bill had come to them in the form of a 12 year old boy, small, skinny, and scared. Ford had explained to Bill who he use to be, Bill took it rather well, asking questions, Ford became like a father to him.

Unfortunately Ford's unanswered questions began to bug him. Ford decided to build a machine that could take them to the Dreamscape, to see what was going on.

Dipper and Mabel arrived for the summer and were filled in of the events of the past few months. After a month Ford had made the machine

"It should work fine, no harm, no issue" Ford said grinning, the machine looked like a Virtual Reality set from that show Futurama that Dipper liked.

Bill was in the lounge still in his PJ's, watching cartoons, eating some toast, his hair all mussed from sleep. The others followed Ford over to Bill "Okay kid, you ready? I explained what where gonna do before"

Bill sat up properly placing his plate of toast beside him, and took a deep breath, he nodded "Lets do this"

Ford pulled out a syringe from his pocket "I need to knock you out, hold still"

Before Bill could protest he jabbed the syringe in Bills neck, the boy slumped forward a few seconds later "Geez Ford, did you really need the needle!?" Stan said

"There's nothing to be afraid of Ley, there usually just for medical purposes, now lets get ourselves into his head"

With a nod from Ford Stan lifted up Bill and took him into the kitchen, placing him into a chair. Ford put the helmet on his head adjusting it slightly, "The gloves first and then the helmets, make sure there secured properly" they did so, Ford checked them all, making sure they were fixed tightly. "Get ready people, where about to venture into the mind of Bill Cipher" Ford said and pressed a few buttons, everything went black.

They awoke to colour, "Wow his Dreamscape is in color!" Dipper exclaimed,

"Yeah Grunkle Stan's was black and white and like a creepy horror version of the shack" Mabel said, Stan looked at her "Wait what!?"

"That first summer, Bill went into your head and we followed him to stop him"

small balls of cyan blue flames led up to a large golden castle that glowed in the middle of Gravity Falls forest, well a version of it, behind them it was all glitchy, lights flickers and wires sparked. "That means that part of his head is damaged, we need to access his memories, they'll be in the castle"

"It hurts my eyes" Mabel said shielding her face.

The hallways of the castle were lined with doors, the first one was pure white with swirls of purple galaxies, kind of like the rift, it said 'Rebirth' in dark red letters "Um guys, I really want to see how Bill was turned into a Demon can we see?" Dipper asked, Ford peered at the door "It may be scary, but I suppose"

they turned the triangle shaped knob, it swung open with a creak, they were met with a room, completely white. A window showed the Nightmare Realm behind it. A boy who looked exactly like 12 year old Bill was strung up on the wall, the door opened and a being floated in, completely black from head to foot, a black sparkly crown on his head, in his hand a large syringe filled with dark liquid "Do not be afraid Bill, we made a deal, you should be honored to become like me, not any of my demon subjects get the honor of my blood to turn them!"

"Please, this is not what I wanted" Bill whimpered tugging at his restraints.

"Shush now child, it will be over soon, then you will be mine forever, I like you kid, your lucky"

"Its the Demon King, the original Demon King" Ford whispered as they watched transfixed,

The King floated over, stroking the boys cheek, he whimpered, the King just ignored him and jabbed the needle into Bills chest, right over his heart. Bills eyes widened and he screamed as the plunger was pushed, it was muffled by the Kings hand.

Tears poured down Bills face, as his veins turned black, The King just watched with amusement, stroking Bills filthy blonde hair. After awhile Bill went limp in the shackles "There, all the painful stuff is done, now for the next phase" the King unchained Bills darkening form taking him in his arms and floated out of the room.

Ford shut the door "That was horrifying" Mabel was crying, Dipper comforted her.
