"(Y/N)!" Dipper yelled, running over to you and waving a hand in front of your face. "(Y/N)! Are you okay?!"

You slowly sat up, still holding the journal to your chest. You looked around the circular room, finding yourself back in the cave. You groaned a little and leaned against Dipper, whose thin legs wavered under the sudden change of weight.

"Are you okay, (Y/N)?" Ford asked, walking over to you and righting you back to your feet. Dipper let out a long sigh of relief.

"Y-yeah... Physically, I guess...." you mumbled. Your vision blurred in and out like a terrible camera that lost its ability to focus. "Mentally... not really..."

"What do you mean? Did that book have something to do with Bill?" Ford continued to question, as if trying to squeeze the juice out of a dried up orange.

"No... maybe... not... directly?" you answered. "I mean... the hawk said there was a prophecy about Bill that the Native Americans knew about..."

Dipper and Ford seemed to be instantly relieved. Their shoulders slumped and their facial expressions relaxed unanimously. Stan and Mabel stood confused to their sudden relaxation.

"We already dealt with that prophecy," Dipper explained. "It was Weirdmaggedon. The Native Americans of the Gravity Falls area carved the Cipher Wheel and an inscription about what was to happen in a cave behind a waterfall."

"I should have wondered why Bill was being more tame. He knows he can't do anything," Ford continued.

You shook your head and muttered, "No, no, no, no, no... you have it all wrong... The hawk wasn't slow on the news..."

Almost as if you had set off an atomic bomb right on the floor in front of you, all four of their expressions froze in horror and fixated their gaze on you. Ford took a step back, his heavy boots slamming on the floor and echoing throughout the room as Stan gripped his brass knuckles and Mabel held onto Stan's arm for shock support. You had explaining to do. And fast.

"The hawk knew about Weirdmaggedon. He said the "Symbols" stopped it before he and the other Native American spirits from the Oracle dimension could intervene."

"The Symbols?" Dipper asked. He took off his hat and looked at it for a moment. "Maybe... it had something to do with the Cipher Wheel?"

Ford, however, paid no attention to Dipper and instead focused his next line of questioning to your mention of the Oracle dimension, "That bird was from another dimension? How could that be possible? Bill's the only thing I know that's powerful enough to enter the mindscape, his dimension between the between!"

You shook your head again, "There's other powerful ones. Well, they can at least project themselves and- to an extent- their powers to our world but they can't really physically touch it? Well, I don't think other than the hawk. I think this book was like a miniature portal..." You held the book out in front of you and examined it for a moment. Considering there was a sealing spell on it that only you could break, that seemed like a very plausible option. The moment Bill told you he was a dream demon from another dimension and made a deal with you was the moment you threw everything you knew about possible dimensions and parallel universes out the window.

Ford asked to see the book. You told him no. If the hawk disappeared like that and the book's sealing spell didn't return, you were certain whatever portal within the book's pages was gone.

"How do you know about other dimensions in the first place?" Ford sneered, rather butt hurt that you would not give him the journal. It reminded you of Bill whenever you withheld something from him- especially food after he almost ate himself to death.

"Bill told me," you retorted, still keeping the book away from Ford's six-fingered hands.

"How do you know you can trust him? That that hawk was from another dimension? A specific one in fact?"

"Well the hawk told me he, and all the other Native American spirits, were from the Oracle dimension!" you said, sticking out your tongue like a small child. "And I hold faith in Bill's knowledge. Plus he loves to show off. Especially with equations I was working on for years. Done in a matter of seconds. He said that all old mythology gods, y'know, the pagan ones, are from other dimensions. Nordic gods are more human-like, Greek gods are more like the monsters. He never mentioned anything about monotheistic gods though."

"Why do you still talk about Bill like that? Like he's some guy you've known your entire life?" Dipper asked, a pang of emotion in his eyes. You knew that look well. Dipper seemed like he was almost jealous. You knew because your ex was a powerhouse of jealousy. Sure he'd hit on girls left and right, but as soon as you weren't home, hiding in a corner at a party he forced you to attend, or right next to him, he would get jealous of anyone- guy or girl- even uttering a simple hello.

"Well, because it seems like I have... I know I haven't, but he's one of those people that show up in your life and suddenly you can't remember ever living without him, you know? And he's... he's not as bad as you think he is... Or as bad as he was... but... right now he's probably worse... because of me..."

"Don't talk like that!" Mabel exclaimed, running over to you.

"But it's true... the hawk showed me. Because of me that stupid prophecy is going to be completed."

"What prophecy?" Ford asked, suddenly gaining attention again. He seemed to have gotten lost in thought staring at the silver hand on the journal.

"I don't know the cryptic message like a prophecy usually has, but I do know because I made him feel terrible..." ("Bill can't feel!" Stan interrupted) "...he's going to go make Mount Hood erupt."

"This is going to sound horrible... but honestly, making a volcano erupt isn't that bad compared to what he's actually capable of doing," Dipper said with sympathy.

"I know, but it's not the eruption that's bad. That was due soon anyway. Overdue, really. What I'm talking about is Bill mentioned something about a... dimensional anomaly, before he laughed and disappeared."

Instantly the room went silent. The first to make a peep was Ford, "A... dimensional anomaly, you said?"

You nodded somberly, "Yeah. And from what I know about Bill and what you guys told me, a dimensional anomaly is not good."

"But then what would be the point of erupting Mount Hood?" Dipper asked.

Everyone went quiet for another moment. And you were the one to gain the idea, "It's in the mountain. The dimensional anomaly is in the mountain."

A collective gasp issued from the four. You could read the question in all of their expressions: "But why in the mountain?"

***

As you all ran through the cave toward the entrance, you tried to explain your thoughts.

Through gasps and short periods of silence, you finally got your point across, "The mountain... it's supposed to erupt every two hundred years or so, roughly..." was the beginning to your breathless explanation. "But it's been on a dry period since Oregon was 'discovered'... So it's reaching its three-hundredth year of no eruption... There was always a rumor, mostly around the kids who heard about Hood's clockwork-like eruptions, that something is plugging up the mountain... Like a giant cork or something...

Essentially the main rumor was the natives.... Their homes were devastated from the last eruption... so they called on the help of the spirits to bring something other-worldly to the mountain so it will never erupt again..." Everyone stopped at the entrance to the cave. You looked up to the small hole in the ceiling, angering the living dirt to be your only way out.

"Go on," Ford said. "You've got a roll going on."

You nodded and continued to explain your thoughts while Ford prepared to move the dirt, "But some kids weren't satisfied with that, so the older ones did a lot of research on Native American lore to find any stories that would fit their rumors. They found one that stated something along the lines of the rumor plus an extra tidbit. This legend said that the spirits complied to their demands, but warned of a time when a great demon would destroy the 'circle,' as it was called, and seal the world's fate with a goose feather dipped in blood. It... mentioned something about a white stag too... but I can't quite remember what it was about."

Mabel looked at you for a moment. Then her gaze drifted toward the goose feather quill etched into the sweater she gave you, that you were still wearing, and drifted again to the quill in your pocket. She seemed to be struck hard with an idea. "(Y/N)... can you repeat what you said? About the sealing fate thing?" she asked in a strangely quiet voice.

"Seal the world's fate with a goose feather dipped in blood?"

"Yeah... I... needed to make sure..."

"About what?"

"I think... I think you're the one mentioned in the legend..."

"Why? What makes you think that?"

It was time for Dipper to interject, "Because of everything. How haven't you noticed? You carry a goose feather quill around with you everywhere. In that carving on the cave door Bill is holding a goose feather, there being an ancient bottle of ink and you being the only one with a quill, (Y/N), Mabel's right... You do have something to do with this prophecy and the legend..."
