Gravity Falls, 1968

A mysterious group of men stand in an abandoned warehouse, all clothed in yellow robes. They stand in a circle around strange markings drawn on the ground in chalk. Weird symbols circle around a larger drawing of a triangle with an eye in it's center.

A man in a robe much fancier than the others, obviously the leader of the group, steps forwards. "My brothers!" he calls, "The time has come for our master to inhabit a new body... And we will be the ones to deliver it!"

The robed men all cheer and clap their hands.

"Jonathan, Matthew, I trust you found a suitable tribute?" The leader asks.

Two men step forward, dragging along a boy no older than seventeen. The boy is tied up and unconscious but it's still clear to see that he's handsome. Pale skin is complimented nicely by messy blond hair that neatly frames his face. Freckles dot across a round nose, soft lips move gently as he breathes, and beneath closed eyelids lay brown eyes so light, they look golden.

They drag him into the center of the circle and step back into their ranks.
"Wake the boy," the leader demands.

A man in the back bangs a gong and the loud noise echos throughout the warehouse, shocking the bound boy awake. He gasps as he sits straight up, looking around frantically.

"What is this?!" he shouts, panic in his eyes, "Who are you?!". He tugs at the ropes binding his wrists to no avail.

"We are the worshipers of Cipher," one man speaks up.

"He is the most powerful demon to ever exist," another continues.

"Every two hundred years, he must receive sacrifice so that he may replenish his strength," calls a third.

"We give him that sacrifice, and in return he gives us seats on his high council and will protect us when he comes to reign," another man says from the crowd.

"We have chosen you to be his next offering," the leader finishes.

"Wait, wait, wait... You're going to... to... feed me to a demon?!?! You can't do that! Please! I don't want to die!" the boy cries.

The men ignore him in favor of starting the ritual. They place candles along the edge of the circle and light them while others approach the boy with knives in their hands. He attempts to get away but some of the men hold him down. He screams as they carve the symbols around the circle on his arms and legs. They carve the triangle figure onto his back. Blood seeps from the cuts and they use some to draw more symbols.

They then reform their ranks and raise their arms towards the sky. Together, they begin chanting.

The boy struggles, panic flooding his senses until the only thing he could think was 'no no please god no'.

Suddenly he stops, being unable to move do to the overwhelming pain coursing through him until he couldn't focus on anything else. He screams and cries and pleads but nobody helps him.

Then, there is a tremendous flash of light. When the light dies away the boy is no longer there, instead, there is a bizarre looking yellow triangle with arms and legs, wearing a top hat and carrying a cane. The men all kneel and bow their heads to the creature.

"Welcome back, Lord Cipher," says the leader.

The creature looks upon his disciples and speaks with the voice of his new host, "Well done, my followers, I am pleased."

"Thank you Lord Cipher," the men state in unison.

If the creature could smirk he would as he takes his host's name, "Please, call me Bill."

Gravity Falls, 2012

The boy, Bill, floats in the darkness, his knees drawn to his chest, like he has been for the last forty-four years, being forced to watch everything he- no, the demon has done. He watches as the demon chases the two children while they fight him. He hopes that they win. Unfortunately, the demon catches them.

The demon is about to kill one of them when the old men shout for him to stop. The one with the trench coat tells the demon that he'll give him what he wants if he leaves his family alone. The one in the suit tells him not to do it but he's too late. The demon shakes the mans hand and the deal is made.

"No..." Bill mutters, hopelessness evident in his voice. If there is any possibility of being saved, it'll become impossible once the demon comes to power. He buries his head in his arms, unwilling to watch the end of the world.

His head snaps back up again when he hears the demon cry out in his voice. "NRUTER YAM I TAHT OS REWOP TNEICNA EHT EKOVNI I NRUB OT EMOC SAH EMIT YM L-T-O-L-O-X-A!!!! STANLEY-" the demon is cut off as the screen shifts to static, then goes black.

Bill is shocked. Nothing like this has ever happened before. Suddenly the screen disappears in a flash and in it's place is the very demon that stole his name and voice and trapped him here.

They stare at each other for a moment before the demon speaks up, "What is this? Where are we?!" He asks, slight panic in his voice.

Bill simply stares at him, watching the demon float around and try to figure out where he is. Bill is reminded of how he did the same thing for his first few days here. The demon looks back at him when Bill finally speaks up, his voice deadly calm.

"Welcome to Hell."
