"It's halfway through the summer, Mabel, and I'm still no closer to discovering any of the real mysteries in the town!"

Dipper sighed as he flopped onto his bed, staring at the ceiling with his treasured journal on his chest. His bed was surrounded with crumpled up paper and notes littered on the floor. Across the room, his sister's bed was a bit neater. There were a few plush toys and art supplies dotted around her bed and the floor surrounding it. She currently sat on her bed, her beloved pet pig Waddles fast asleep with his head on her lap. The twins were currently avoiding work in their great-uncle's tourist trap, The Mystery Shack.

"Aw, not this again," His twin sister Mabel sighed, as she glanced at him from her own bed across the room. In her opinion, Dipper was WAAAAY too obsessed with the whole thing.

"I mean it. I don't even know who the author of the journals is!" He exclaimed, throwing his hands up in frustration. Mabel looked at him, her head titled slightly and lips pursed in a small pout with confusion and pity.

"We tried, Dipper!" she said, a hint of hurt in her voice at her brother's frustration. She didn't like to see him angry or upset.

"But it's not enough!" Dipper scowled, before noticing the expression of hurt on Mabel's face. Waddles stirred awake, disturbed by the noise. He hopped off Mabel's bed and trotted out the open door, in search of a quieter enviroment to nap. Dipper's expression softened, and he gave his twin sister an apologetic look.

"Well, maybe we just need help.." Mabel suggested. Dipper considered this, his brow furrowing as he thought. Suddenly, his expression brightened. His eyes lit up as he sat up straight on his bed, unintentionally scattering paper onto the floor.

"Wait, we could do that!" he said excitedly. Mabel, not quite understanding, nodded anyway. Dipper smiled at her as he continued. "I mean, there has to be some kids in Gravity Falls willing to help, right? We can get a group together! Just think, Mabel! All of us working together, we could make some real progress!" This could be his chance! All summer he was searching, and was still no closer to solving the real mysteries of the town! But with more like-minded people working together, he could do it!

Mabel nodded eagerly, excited at the proposal.

"And we could have slumber parties, and-" she began, before Dipper interrupted her.

"Solve all the mysteries in the town!" he finished for her.

"Yeah! That too!" Mabel agreed. Dipper stood up, and starting pacing the length of the room. "We can call it, THE-SUPER-AMAZING-FUN-MYSTERY-STUFF-IN-GRAVITY-FALLS-CLUB!" Mabel exclaimed in one breath.

"No, definitely not," Dipper said, shaking his head and adjusting his iconic pine tree hat on his head. "The Gravity Falls Mystery Guild!" This earned him a giggle from Mabel, who was now lying across the width of her bed with her head hanging off the end.

"That sounds dorky!" she noted, snorting a laugh as she watched Dipper up-side-down from her view.

"We need to get the word around," Dipper realised, ignoring Mabel's remark. "Do you think you could make some posters?"

Mabel sat straight up, and her eyes lit up like a child on Christmas.

"I'll get the glitter glue!"'

And so it begins, folks! Sorry it was so short, the real chapters should be longer!

So, this is a SYOC. I am looking for characters to join 'The Gravity Falls Mystery Guild!' Fill in the form provided (which will also be available on my profile for copy-and-paste ease), and submit it to me. Preferably, I would like it to be submitted by PM, but I will allow guest users to submit by review.

Extra Information:

In the Point of View of your character, why should you be in the guild?:

That's just about it! Before you submit, please read the guidelines on my profile!

All OC's MUST BE SUBMITTED BY JUNE 17TH, 2015. It is NOT first-come first-served. I want a balance of girls and boys in the guild. The guild will consist of Dipper, Mabel, my own OC, four other males and three other females.

As far as when this takes place, I'm not really sure. It is pretty much AU. Everything in Season 1 has happened, and the Mystery Shack is rebuilt, but the events of Scary-Oke haven't happened yet. There will be some one-shots in this story mixed in along with the main storyline, which may consist of the characters in various alternate universes in the fandom. The OCs would probably had a small encounter with the supernatural, but managed to slip under the radar of the Society of the Blind-Eye; for the sake of the plot!

Also, constructive critisism is welcomed! If there are any spelling or grammar mistakes, please let me know! I wrote this quite late at night, so I may have missed something! I also want to do the great charcters of Gravity Falls justice, so if you think anyone is too OOC, tell me! Well, I think I've covered everything! Head over to my profile for more information!

Until then, buy gold, BYE!

Author's Note, 6th of June: Wow, the response was beyond my expectations for this story! Thank you for everyone who left the kind reviews, they made my day! And thank you for everyone who sent in an OC! I have to admit, I was really impressed! It is going to be really hard to pick! I'll let everyone know who is in on June 17th, the deadline for all OC submissions. Until then, keep submitting!
