Prologue

She watched quietly, her eyes peering down at the back of her sibling, her attention barely focused on the nails she filed sharply to perfection, her twin brother perused a book with six fingers imprinted on to the cover with a large golden number 2, his eyes drinking in the words as each second that passed.

A sudden slam, and their attention were stolen away from their current activities, instead their eyes met before looking at the hulking figure that shared similar features to them, a man they called father. The man's gaze pierced into them, watching as his son carefully closed the book in his hand, placing a bookmark in between the yellowing pages, and he was startled to realize that he didn't recognize it from any of their collection, his son met his gaze, his body turned towards him unfazed, ignoring the silent question, while his daughter didn't spare a second glance to him, finding her nails more important, for a second her fingers curled and to his observation. They were almost like claws.

"Mason...Mabel.." His voice rumbled, dark brown eyes staring intensely at the now ignored book, questions running through his mind "What is this...?"

Mason only glanced at the side, his eyes filled with disinterest, compared to how he held himself earlier, and a a quirk of her lips expressed amusement at the idea, paying little mind to the man, wondering how long it would take for him to be take for him to leave, Mason sighed, irritated, before answering, "It's a book we found at an antique store recently." He lied easily, before changing the subject, "Did you need something?"

Mabel was quiet, knowing that the book wasn't exactly recent but something they came across in their early youth, constantly hiding it and utilizing it for their own ambitions and benefit. She waited for his response until his heavy footsteps indicated he approached them.

Dipper was handed a thick folder, and silently he opened it, and an annoyed sigh left his lips, "Is this all?" his expression unchanging as his blue eyes met his Father's dark eyes.

"The reports say that you're losing the public's interest." He said angrily, "Your ratings are going down!"

Dipper muscles didn't even twitch as he removed his glasses, "Please refrain from shouting." he said stiffly as he placed it beside the book on the desk.

He bristled in anger, "We are losing money, Mason!" he growled as stared their bored expressions, "I wouldn't have kept you ungrateful brats if you weren't keeping a steady income to this household!"

"...Father, we must dearly apologize for...lacking to reach your expectations, However I fear it is as we expected." He stated simply as he sat down, fiddling with the amulet on his chest, it glittering every once in a while.

He was silent as he questioned, "...As...you..expected?"

"We continuously follow the same routines you've provided us for all these years, The people are bored of the same routine, and we've been working on something new..." Dipper said, his intense stare didn't look away from the man, "..it is time we begin expanding what's in our repertoire, our talents and to..."

"Experiment." Mabel finished quietly, interjecting herself into the conversation, tilting her head upwards, all attention on to her brother as her eyes glinted with sadism, "Are you thinking... of what I'm thinking, Brother?"

Their Father stood in silence as he stared them down, a slight chill crawling up his spine, "No." The man said, disgust in his eyes, "Nobody needs to know how much of a freak you two are...!"

An unladylike snort left Mabel as she smiled, her eyes unreadable as a strange smile crossed her lip, "Daddy dearest, is that any way to treat your children?"

He stood quietly at the door and didn't meet either eyes, as he felt dread crawling up his spine.

"Father...We would like your permission to travel to the town that our Grand Uncle resides in..." he began, his voice soft as he waited for his answer.

"No." he immediately rejected

The two stared at each other before looking at their father, and Mason raised an eyebrow in question, "No?"

"You aren't going to that...Town," He spat in disgust as he looked into both of their eyes, "Not again...not after—"

Mabel's eyes glowed intensely, her amulet following suit excitedly, an eerie blue light, staring into her Father's eyes and he grabbed his hair, a pained expression crossing his face, messing up the neatly combed brown locks slowly his eyes glazed over as he began to dissociate, and he whispered, "Not after...what was I saying...?"

"Don't you think it would be nice for us to see our old Grunkle Stan again?" Her smile grew further, revealing sharp teeth.

"Ye...yes..." He shakes his head, his eyes dilated as he shakes on his feet, blood beginning to slide down his nose onto his lips, "I think ...I think...I should stay...sleep...you two can take care of yourselves..."

He disappeared through the door, although unsteadily.

"Really, you can't keep doing that...He is our father," Mason said in amusement, he pushes the papers towards her, getting them out of his way.

She hummed, "We know you don't really care about him..." she said as she twirled a brown strand of hair around her finger, "I don't even know why you even bother asking for permission, you're truly too nice to the man."

He ignored her statement, amusement dancing across his eyes, "At this rate, you might kill him, don't you think?" He said as he removed himself from their seat, book on his side and glasses now in his pocket.

She stared at him, a smile persisting, strained as her eyes darkened, "And it will be well deserved I would think."

"I never said it wasn't." He tilted his head and nodded at her. "I will be in my bed chambers."

The door closed behind him quietly.

She stared at the door, before her gaze wander towards an old picture, a picture of them standing together, a fake smile on both their faces as he stood behind them, hand on their shoulder, what no one noticed how tight his grip was at the time, the only indicating such events were how white his hands were, she moved her attention to the table and got up, picking up the almost forgotten file when her eyes caught her name. A smile at the message, with familiar hand writing, left behind by her brother, "That's not very fun."

Mabel,

Clean up the mess you left.

Brown skinned and a wide grin greeted a boy who had his nose stuck into a book, plopping down right in front of him, " Did you hear?" She asked, excitement leaking out of her voice, staring into his brown eyes that peered at her through thin square glasses.

"About what?" The boy responded to the fake blonde, barely even glancing at her, his interest returning to the book in hand.

"The Mystery Twins are coming here!" Excitement leaked from her voice as her eyes sparkled in delight.

"...And who is that?"

She gasped, "Do you even watch TV?!"

"I have better things to do than have my brain be rotten by the stupid things they show on Television nowadays," he said scornfully, burying his head further into his book as if to escape from the conversation.

Shaking her head from exasperation, "Okay, Boomer, sounding like a real old man... "

He frowned in response as she looked him in the eye, "I'll enlighten you then," she stated "They are a Famous duo known for their illusory tricks to delude the mind, there's conspiracy theories that they really have magic and sold their soul to the devil to gain their current fame and popularity—"

He interrupted,"Sounds like a bunch of hogwash,"

She continued, ignoring his attempt at ending the conversation, "...as they seem to hold unbelievably unexplained powers that even put other magicians to shame! Like there was a behind the scenes secret video of them where the girl, her name's Mabel by the way pierced through volunteers with a bunch of swords and there was blood and screams but when they opened the door, she was perfectly fine..."

"...Sounds gruesome, seems like they have better planned effects to make their audience believe in their tricks and such, going so far as having as if it was a secret video with probably some believable actor or actress and editing" He shrugged, "So what? Still not a big deal about a pair of magicians coming down here..."

"...Well I think it's all real but whatever," She shook her head, and sighed "No point in even trying to tell you...You won't understand..they are really a big deal and are even on TV but you don't even watch that because of your weird beliefs."

He scowled indignantly, "first off, they aren't weird"

He sighed and asked, "...and secondly,why are a pair of so called big celebrities coming down here in a little town like Gravity Falls in the first place?"

"That's the thing, no one knows why..." she said hesitantly, "...But best not to look a gift horse in the mouth, right?"

"Seems weird..."

"We should DEFINITELY go!" She said in a pleading voice.

"No."

She immediately began begging, "Please, this is a once in time opportunity!"

"Still No."

She sighed, "You sir are truly stubborn, " and a sly look crossed her face as she pulled his book down, forcing him to look at her.

"I'll invite Pacifica."

"...Doubt she'll even come..." he said, trying to bring his book back in an attempt to hide the oncoming blush spreading across his cheeks as he finally succeeded in burying his face back even further into his book.

"She already agreed." A triumph look crossed her face as she grinned at him.

"...Fine."

She cheered, before she added as an afterthought, "She's also bringing that kid that's always clinging on to her...I think his name was Gideon?"

He groaned, before getting a word out, the girl immediately said, "No takebacksies!"

He only sulked. and she patted his back, "Maybe you'll get lucky and end up being alone with her, fall in love, share your first kiss, start dating—"

"Shut up...!"

"Anyways the Gideon kid is probably cool so, I don't mind hanging with him while you confessed your undying love for her!"

He stayed silent not even commenting, and she only grinned at him, "Anyways, gotta go and make to be the best bad influence I can be to my sweet darling Pacifica~" she chirped as she got up to left as he sent a glare at her.

"Bye bye!"

A frown on his face as he pulled the book away from his face, revealing the matching shade of red on his face to the color of his hair.
