Dipper trudged through the hallway full of flooding skulls, and pushed on the door with all his might. He felt the creaking and groaning of the boards until they came to and smashed. The molding boards led way to the ancient room. Dipper stepped through the door and Bill hovered through. Bill stopped suddenly and curled up.

"Her….." His form was glitching and his two-dimensional form seemed to become translucent for a couple seconds.

Dipper turned around. "Ar-are you okay?"

"hrgh, yeah, keep going. It's just happeni-NG because of the room and the Stone."

Dipper peered into the room and what he saw chilled him to the bone.
There, in the center of the room, was a giant circle with all sorts of geometric shapes and lettering. In the center of the perfect circle sat a skull, staring at him with its sockets, and one large lump, accompanied many other smaller lumps, decorated its head. On the sides of the wall there were sticks, which he assumed were torches at one point. Covering the walls were old sheets of papyrus, which hieroglyphics painted onto them, many with Bill's likeness. They appeared to be pealing, and Dipper was afraid of what laid underneath the paper. He turned behind him, and saw Bill glitching again, as if he was a file being manipulated on a computer. As if a television lost satellite connection, or a phone broke shattering the interior. His triangular shape changed forms second after second, turning into different kinds and shapes of three-sided polygons. Dipper could hear Bill breathing heavily, and sound of gritting teeth, excruciating to listen to.

Dipper made his way over to the skull that mocked him so, and swat away the dust and cobwebs covering it. Different kinds of gems illuminated and sparkled with the light of his flashlight. Jaspers, sapphires, emeralds, sardonyx, and types of opals. What appeared to be the largest stone, straight on the forehead, was one he had never seen before. It was as if it changed colors, a multitude of hues that leaped across the color wheel as often as it changed its cut. It felt alive. Dipper went to touch, but it produced an aura that made him reconsider.

"Alright, what do we do now, pinhead?," he asked Bill.

Through the gasping of breath and the moaning of pain, Bill muttered. "Take…some of that … blood… and draw a pine…tree…and a triangle… on each s…ide of your palms."

"THIS IS BLOOD?!" Dipper screamed as he jumped back and landed his back against the wall. He hit him hard and Dipper felt the room churn.

Bill hissed. "Hurry!"

Dipper crawled back over and drew the pine tree symbol that resided on his hat many years ago on the top of his left hand, and with steady fingers drew a triangle on his right side. He felt a hum, a vibration moving through the room like the air itself was starting to create energy. Bill shrieked and Dipper covered his ears, thankful he was the only person who could hear Bill's agony. One by one, the stones on the skull lit up, and radiated its colorful reflections on the papyrus walls.

Bill howled his name out "WILLIAM CIPHER, TRICKSTER AND CHAOS MAKER"

Dipper turned to him, who no longer kept any kind of form, and black claws scratching at what must be an eye were all Dipper could make out of his demon friend. Dipper hesitated, and called out his real name.

"DIP…MASON PINES!"

The circle of dried blood melted, and became liquid once more. The smell of iron flooded the room, and the blood, still in the shape of the alchemy circle, lifted itself off the floor.

"X-O-L-O-T-L!" A voice, more of a roar, cried out. "my time has come to transform! I invoke the ancient power that I leave this body to burn!" The hum in the room turned to a piercing sound, and the scarlet blood turned to a glowing cerulean. What sounded like a hundred mutilated screams filled the air. Dipper, still in the same place as before, crouched and covered his eardrums. The stone that refused to stay one shape and color lodged itself away from the skull and levitated in the center of the circle floating. Dipper felt his head pounding and his ears felt as if they had pierced. Yet, with the muted sound of screams, Dipper could hear a whisper in his head.

The torches, boy. Light the torches. Dipper stood up, dizzy, and drunkenly worked his way over to the first torch near him. With exasperated sighs, he took it off the wall and looked around for something to light it with. He saw Bill's interdimensional chaotic form, not triangular anymore but changed as often as the stone in the center of the room did. He plunged the torch into Bill's body(?) and immediately took it out. The fire lit now on the torch was red as a garnet, and Dipper hurried back to its original position on the wall. As Dipper struggled his way around the room, he lit each torch the same way, and each its own different color, creating a rainbow of fire across the room. The stone stopped changing forms, and turned into a glass pyramid. However, the reflection of the fire shot light inside, creating a rainbow within. In opposite of what Dipper knew to be true, it shot out pure, white light up to the ceiling. The light became liquid and began to drip onto the floor. It hugged Dipper's feet, and wormed it way up his body. Dipper tried to stomp his legs to get the light off, but the blinding parasite, chugged on forward on his body. Suddenly, all of the noise in the room had stopped. Dipper looked over, and saw that Bill was covered with the light, and was being dragged down to the floor. Dipper couldn't help the light that now paralyzed him, and flooded his lungs as he screamed out before the light swept over him. It went down his throat and tasted like milk and honey. But all he could see was white. White around him, and his body was no longer visible to him. Suddenly, the skull from the room flashed in the center of his vision. It moved towards him quickly, and it opened its jaws wide. Dipper had no time to react before he was launched into the jaws of the skull.
