I am back after a long time of not updating! Anyways, this is my first gravity falls fic, so please don't write bad reviews, please!

It was raining outside on that warm Saturday evening, and Dipper should have know that something terrible would happen. It was raining when Gideon swore his revenge to get the deed and brought forth the notorious Bill Cipher. Cipher had then went into Stan's mind and tried getting the code to the safe which held the deed. If if wasn't for Mabel, Soos, and himself, the world itself would be falling apart. He should have know something like this would happen, but he didn't listen. He should have.

"Snicker doodles! " Mabel cried, placing her king in front of Dipper's king.

"Mabel, that's not how you play chess. Now we're both at a checkmate." Dipper looked at the window and his eyes widened. Did he just see a triangular shaped demon in the window looking at him? Dipper quickly shook off the thought and went back to playing chess. It was then that he noticed that all the horses had "mysteriously" disappeared.

"Mabel, give back the horses." Dipper deadpanned at Mabel, who smiled sheepishly until running away quickly.

"MAAAAAAAAAAABEEEEEEEEEEEL! Come back here!" Dipper shouted before following his sister down the hall.

Mabel twisted and turned down halls going left and right until Dipper himself didn't even know where he was anymore.

'I've never seen this hall before.' Dipper thought 'Is this even the Mystery Shack?'

"Over here, Dippingsauce! Come and get it!" Mabel held up a horse to taunt Dipper even further.

Dipper charged at Mabel and grabbed her hand. His eyes widened at the feel. It was stone cold.

"Y-your hand..."

Mabel grinned darkly. "Haven't you LEARNED Pine Tree?"

'Pine Tree?' Dipper thought. 'Only one person I know says that and it's...'

"That's right, Pine Tree! It's me, your friendly dream demon, BILL CIPHER!"

He snapped his fingers and transformed from an innocent, sweet, and loving child to a devious, conniving, dastardly dream demon.

"What do you want? I thought you left us alone for good after getting rid of you in Stan's mind!" Dipper tried to use bravado, but even Mabel could see through his act.

"Oh Pine Tree," Bill smiled while looking at his hand/arm in boredom. "I always knew you carried powers that could surpass even mine. The first time I saw it in action was in your nut of an uncle's mind. Defeating me was no easy task, dear boy."

Dipper looked up in surprise. "Wha-"

"So, I came to ask you to be an apprentice of mine. You can learn all you want about the world. You can even learn who write 3." Bill looked at Dipper, who now was more shocked than ever.

"H-h-how did you...?"

Bill looked at Dipper smugly. "Kid, I know LOTS of things. Now do you accept?" Bill held out his hand.

"NO! You tried hurting my family and you worked with Gideon! Why should I?"

Bill shrugged. "Now you're just asking to do things the hard way."

He then grabbed Dipper's hand and muttered some words and slowly, Bill began to disappear.

After Bill had completely disappeared, Dipper looked at his hand. There in his palm, was a tiny triangle with one eyeball. It winked.

There ya have it! My first chapter! I know it might suck a lot, but no flames please! Some nice reviews would be very nice, thank you! R&R please!
