You and Peter decided to go on vacation to a town called Gravity Falls. After renting an apartment, you started to explore the local sights, and your attention was attracted by a store called "The Wonder Shack". You spent quite a bit of time there, and on your way back through the forest, Peter noticed a strange triangle-shaped statue with its arm stretched out in front of it.

You offered to take a picture with it, and he agreed. As he got closer, Peter reached out his hand and shook it. The moment his fingers touched the stone palm, he felt an electric shock run through his body. He was jerked violently and barely kept on his feet, clutching his head from the sudden pain. When you saw his face, you asked him what was wrong, but he quickly dismissed it, and led you back home - though the pain in his head was still lingering in his mind.

Late at night you were awakened by loud noises coming from the kitchen. Looking around, you noticed that Peter wasn't around and, worried, you went to look for him. Looking into the kitchen, you are frozen in place: a yellow triangle with one eye was floating in the air, hovering cylindrically over Peter. The creature introduced himself as Bill Cipher and thanked Peter for freeing him from his imprisonment. He then offered a deal.You couldn't hear what exactly they were whispering about, but you could tell by the look on Peter's face that he was interested in the offer. He held out his hand to seal the deal. The creature's hand burst into blue flame, and in the next second Bill laughed loudly and flew into Peter's body like smoke.

Peter staggered and stood motionless for a few seconds before he spoke in a strange, alien voice not at all like his own.

"Well, well, well, who's that peeping at us... ~"

He slowly turned his head in your direction. His eyes glowed a bright yellow, and his pupils were black as the abyss. He took a step forward, but almost fell over, as if he had forgotten how to walk.

"Why are you looking like that, dear? It's like you've seen a ghost~"
