A/N: Hello guys! Thank you SO MUCH for reading, following and favoring my fanfic!

P.S. I would like to thank my AMAZING friend Roi who'd wrote the prophecy for this chapter.

Okay, no more talking. Read and enjoy! (once again – I do not own Gravity Falls.)

Chapter 3 - The Prophecy

Agent K. Trigger knew the cab was a distraction as soon as it drove away from the Mystery Shack. He knew his target too well – he needed to get back there, and nothing could stop him. Not even the FBI. He ordered a few agents to find the man, just in case it really was him in the cab, and then got back to the Shack on his own.

Just as he thought, when he'd returned the other agents already left. But surprisingly there was someone outside the Mystery Shack. He was just standing there. Waiting.

It was Stanford himself.

What's he up to this time? Thought Trigger as he stepped out of the car, aiming a gun at the escaped criminal, who looked like he'd just lost in a battle against a tornado.

"Stanford Pines," cried Trigger. "I put you under arrest. Anything you-"

"Yeah, Yeah, anything I say may and will be used against me, blah, blah, blah. Would you please hurry?"

Well, he certainly did not expect that. Well, I guess it doesn't really matter. Besides, I'm armed and he's not. What can he possibly do? Trigger approached to him. The man didn't even try to escape - does he really surrender? - as Trigger handcuffed his hands and marched him toward the car. Once they were inside, Trigger started the car and drove away.

They drove in silence for a while, then Stan said, "You're not gonna report you got me?" he asked and glanced at the window. He saw more and more trees by the roadside. "By the way, shouldn't you take me to the police station, not the forest?"

The agent didn't respond. Don't worry, he thought. All will become clear soon.

Pacifica Northwest sat on her bed in her big bedroom, though right now it made her feel stifled.

After last night's events her father was so mad - he hit her again, for the first time in a year and a half, and locked her in her room.

And honestly, it didn't bother her. At least not until she started to float.

"What the hell-" she tried to hold on to her four-poster bed's poles and pull herself down, but she failed. Whatever made her lift was now holding her close to the ceiling, but far enough from the chandelier to prevent her from reaching it. But she wouldn't dare to try to move anyway.

Suddenly everything around her turned grey, and even time seemed to stop. A voice, which seemed to come out of nowhere, said, "Calm down, it's alright. I can help you."

Pacifica glanced around. "Who are you?" she cried. "Where are you? I can't see you!"

"Over here, on your right!" the voice answered. She turned her head to her right and saw an outstretched hand, wearing a black glove, but not the body to which it belonged. "Take my hand!" said the voice, and this time sounded more aggressive.

Pacifica hesitated, but she had no choice. The mysterious force which held her in the air became weaker. It will soon fade completely and let her fall. She reached her hand for the other one, it felt odd, as if trying to hold the air itself in your hand. The voice laughed, a terrifying laughter which made Pacifica shiver. To her horror she realized - too late - that there wasn't any glove on the hand. The hand itself was entirely black. "And now, Llama," said the voice, almost whispering. "You're mine."

He pulled her closer to him, the world around her swirled in a whirlwind of colors, and then… nothing.

"It's time," said the Author. "Let's go." With the Journal #1 and #2 in the Author's coat, and Journal #3 in Dipper's vest, the four of them walked toward the elevator.

When they climbed the stairs toward the secret entrance to the underground lab, the door was blocked. "Damn it," hissed the Author. "The vending machine must have fallen on the other side." he gestured for Soos to come closer and together they had managed to push and open the door so the four of them could pass through.

The world outside seemed like a wreck - the Mystery Shack's furniture were overturned and scattered throughout the room, pictures fell off the walls, and the roof had probably collapsed inwards due to the wave of destruction that the portal released once it was open. A few trees outside were ripped out of their place and fell on the road. A few other houses in the town looked like ruins but most of the damage was caused to the Shack.

At least the car was fine. And surprisingly, still on the ground.

They made their way to it through the ruins of the house, every now and then stopping to divert wood beams, which had fell from the attic.

At last they managed to get out. Soos gave the car keys to Stanley, who sat in the driver's seat and started the car. Soos sat next to him, and Dipper and Mabel sat behind them.

"Where are we going?" asked Mabel.

It seemed that the Author didn't hear the question. Instead of answering he said, "Dipper, would you please find the page about Bill Cipher in Journal #3."

Dipper did as he said and opened the Journal. "Found it. But I've read this part a million times before, there's nothing-"

The Author didn't seem surprised. "Turn on the ultra-violet light."

Dipper turned on the ultra-violet lamp. A new text appeared in front of his eyes, and his eyes widened with surprise. "Umm...what's that?"

"Read it," Stanley ordered.

"Okay..." Dipper cleared his throat and read something that sounded like an ancient prophecy:

When the Ten will gather, the world will be on its demise,

For a triangle demon will be summoned and arise.

But if the ritual is flawed, even by one mistake,

He will be banished, and the life of one of them he'll take.

He looked up and asked, "What does it mean?"

Without saying a word, Stanley pulled out of the pocket of his coat Journal #2 and handed it to Dipper, and kept driving with the other hand. "Creature number 326."

Dipper looked for the page until he'd found it. "But...it's Bill. Why…?"

"Pay attention to the Symbol Wheel. It has ten Symbols, right? That's what the prophecy you've just read is about. The ten symbols represent ten people, who are supposed to perform a ritual which would summon the demon from the center of the wheel - Bill Cipher - to our world, with his full power."

"Can't we do something to stop him?" asked Mabel.

"Unfortunately, at this point, the ritual is inevitable - one way or another, it will be performed. The only way to stop Bill is to disrupt the ritual once it's already started, so that Bill will return to his dimension and stay there, trapped forever. The problem is, that disruption the ritual would require a victim - one of the Ten who will wake the demon."

"Well, that shouldn't be a problem," said Dipper. "These people probably cooperate with Bill, right? So we just have to interrupt during the ritual, and then Bill will be banished and one of them will die."

"It's not that simple. First of all, these people do not cooperate with Bill. Some did before, but nowadays…"

"Sounds like you know who these people are. Why wouldn't you tell us, so we'd know who are we gonna interfere?"

The Author looked directly at him through the car's mirror. "For starters, you."

Dipper was left without words, the color drained from his face in surprise. "What?" asked Mabel.

"You too. Actually, Four out of the Ten are sitting in this car right now."

"Can't be," murmured Soos. "None of us is gonna summon Bill."

Stanley sighed. "No one ever said the Symbols would do it voluntarily. In fact, we were safe, and I thought the prophecy would never come true, until my brother opened the portal and brought me back to this world. As long as one of the Symbols is missing, one cannot perform the ritual. But once all are united…" he sighed again. "If I'd return earlier, I could've done something to prevent this. Or I'd stay in the other dimension, and then nothing would happen."

I was right, Dipper thought. If Mabel would shut the portal down, Stanley wouldn't come back and the prophecy wouldn't come true. And now we're all doomed.
