Thank you to everyone who has read the story and put up with the infrequent updates And for anyone who also reads A Demon's promise, that will be updated soon too!)

Bill froze in place, "Well well well, looks like Shooting Star, has some final words."

She stood up and walked over to "Stan" grabbing him by the arm and roughing pulling him up to his feet, the bonds snapping, "I was just wondering why Grunkle "Stan" had six fingers?"

"Mabel?" Ford asked, "What are you doing?"

Bill laughed, "Isn't this interesting, you almost got one on me. I suppose the act is over Shooting Star."

"Act?" Dipper asked with a groan, struggling to sit up.

"Sorry, bro bro." Mabel said with a smirk, "You three really are dumb." She pointed at Ford, "You'd think that somebody who claims to be an expert on Dream Demons would be better at not being manipulated." she walked to her brother and grabbed his neck, lifting him up,"So, Ford, you can let Bill into your mind now, or you can watch me break every bone in my brothers body. Your choice"

Ford looked down, clenching his fists, "Fine." He held out his hand to Bill, "We have a deal, Bill."

"Smart choice." Bill said, hand bursting into flames "Shooting Star, keep the other two here. Alive. And if they try to run, break their legs" He shook Ford's hand, turning to stone and entering Ford's mind.

Mabel tossed Dipper to the ground, ignoring his coughing and wheezing, and not even acknowledging his pleading look, "Mabel...Why? We're your family." Dipper said eyes on her.

"You were my family" She corrected, "To put it simply, I'm a demon. When I accepted the deal to get more power like him I didn't know his plan,I didn't realize he needed me." She hovered in front of them, crossing her legs, "Well he needed to break the wheel. How else then by turning one of the members to his side."

"But why you? You knew him." Dipper asked

Stan still hadn't said a word, he simply stared at his brother.

"You're right, I knew him. I knew he was powerful and dangerous, and I knew he would find a way to come through on his threats to hurt you." She looked at Stan and rolled her eyes, "It's not like he's hurt."

"I think we both know that's not true," Stan said not looking at her, "He trusted you."

"No, he didn't. He trusted my power. I'm not an idiot, I knew he was uneasy around me even before I was a demon, and I now know why I was too much like you. Like his stupid impulsive brother who ruined his life."

"You're wrong," Dipper said, "He cared about us, both of us!"

"I'm not. You only think so." She glanced at Ford, "He won't be too much longer." She shook her head, "If you weren't so much like him he wouldn't have bothered with you."

"We can still stop him."

"I don't want to stop him Dipper. I'm having fun. This is fun."

"You're hurting innocent people."

She rolled her eyes, "Oh no, those poor people." She muttered sarcastically, "Besides it's not like they're conscious."

"That's not the point Mabel."

"Then tell me, dear brother, what is the point? They aren't in pain, they aren't conscious, instead of hiding away in hopes of surviving they are fine."

"How is any of this fine. They are trapped same with them" Dipper pointed to the walls, "How can you be okay with this?"

"This is getting tedious." She said, "Look," She turned Dipper's head, "Bill should be back shortly with the information we need."

"Mabel." Dipper pleaded, "Please stop him. This doesn't have to happen. We can destroy him with the memory gun. Just let me get it."

"Not happening." She said, "And if you try anything I'll turn you to stone. Actually, if you keep talking I'll turn you to stone."

Dipper walked over to Stan, who wrapped an arm around him, the pair silent.

Minutes later Bill exited Ford's mind looking extremely pleased with himself

"So, what do we need to get out of here?"

Bill straightened his tie, and took his seat, "It's not that hard, once we finish this we let them go and then the rest of us are leaving this hick town." he flicked his hand towards the barrier, his magic pulsing outwards, the ground shaking

Mabel frowned, "But what about them, you said I could..."

Bill cut her off, "Forget what I said Shooting Star, we have bigger fish to fry, an entire universe to rule. The deal was we let them go, and Sixer would give us the equation, so we're letting them go. Besides, do you really want to hear their prattle while you decide what to do with them?"

She laughed, "I guess not."

Bill looked at the remaining Pines, "Well it's been a blast, but it's time to move onto bigger and better things, enjoy your final moments of peace" He snapped his fingers the trio landed on the ground and the pyramid vanishing, the town eerily silent, as if the weirdness followed its masters.

Ford clenched his fists glaring at the sky where it was, "I should have known. I was foolish to fall for her tricks."

Dipper closed his eyes, "We need to figure out some way to get her back, get her humanity back. She's not Ford, there has to be some way."

"Dipper, I don't know. A human becoming a demon. I've never found documentation of it in my travels. But I agree with you, she isn't herself, I just don't know if we can get her back, and if we can, how."

"Well, how about we check to see who's left in the town and plan from there." Stan said flatly, "There's no point in focusing on getting her back right now when there are others we can actually help." he turned his back on the pair and started walking away.

"Stanley." Ford said, "I agree we need to help the people who are left, but we can't ignore the problem."

"You mean the problem that we all allowed Mabel to reach a point where Bill could take advantage of her? Or the problem that instead of dealing with one psychotic demon, we're dealing with two, and one of them is our niece, because both of them seem pretty big problems that we can't solve so we're going to ignore that problem until everyone else is safe, or as safe as we can be while the pair of them are running around." He ran a hand down his face, "Some sleep might be nice too." he trudged towards the area the mystery shack had landed, still mostly intact, his shoulders slumped as if he had the weight of the world on his back.

"Grunkle Ford, what if we can't bring her back?" Dipper asked watching Stan walk away

"Do you want the truth?" Ford asked, "Because you won't like it."

Dipper tensed, "We'd have to get rid of her too." he guessed looking like he wanted nothing more than Grunkle ford to say "No not at all."

Ford nodded solemnly, "Guessing at how fast they tore through Gravity Falls, I'd say we have less than a fortnight before Earth is destroyed. That much time to stop both of them or else our universe will end. We're going to head to the basement right now while Stanley looks for any survivors, we need to see if we can find something to fix her, or we need to find out a way to send them both away." he placed a hand on his nephews shoulder, "I need your help...do you think you can do this?"

Could he do this? Hurt his sister? Even if it was to save the world…"I don't know Grunkle Ford"

"I suppose I can't expect that of you, We'll figure something out." he squeezed Dippers shoulder, "But I do think you should try and get some sleep you look dead on your feet."

Dipper did feel like he was about to drop, "Alright, you should sleep too." he trudged towards the shack, "I don't blame you, Grunkle Ford, no matter what you think this isn't your fault."

"Thanks, kid," but you're wrong. He turned and headed into the destroyed town, passing by burning buildings and ruined storefronts, before heading into the forest, to where the shack originally rested, there wasn't much he could do without help. Though he abhorred the idea of going to her, they made unicorns easy to deal with. Sitting down he closed his eyes for a few minutes, the clearing calm. He had no fear that anything would harm him. Even the traditionally violent creatures would be expecting Ford to be the answer. But Ford wasn't sure he had an answer anymore.

_

Everything was on fire. They started by burning the rest of North America, the screams of the pathetic humans and scent of burning flesh filled the air, the henchmanics. Those who had survived bowing in submission to the demons that they had feared, prayers hadn't saved them, but maybe these creatures would give them mercy.

Mabel giggled as those who tried to offer tribute were swiftly...eliminated. And as days passed, the fun never ending, Mabel left with Bill moving to South America to continue the process, growing the fearsome creatures that lurked in the jungle to enormous sizes, the animals preying on the surrounding towns, and on and on and on. The process never getting boring, the cries of pain music in her ears.

With Fords help they managed to get the television working in a couple days so they could get updates on the damage around the world, The remaining townsfolk together in the shack, trying to stay alive. The updates were usually brief as the television stations were quickly destroyed. Dipper was hardly paying attention to the story, his eyes on the corner where the date was posted August 31st. He felt his arm being pulled by Ford,

"I think I know a way to stop this," Ford said, dark circles under his eyes. Desperate times called for desperate measures.

"How?" Dipper asked.

"Have you done any research in Faerie lore?"

"You're joking."

"I wish I was," Ford muttered, "I'd rather try and reason with unicorns."

The pair continued walking, "When in the realm of the Seelie, do not apologize or say thank you for anything, or you will have indebted yourself to them, do not eat or drink anything unless I say it's safe, and do not accept any deals. Even the most harmless offers can be dangerous," Ford paused, "And above all, do not ever give them your real name. I made that mistake the first time I was here, and I have had to provide many favours in order to keep myself alive, as you may have figured out they are more cunning than Bill and as lethal."

"Then why are we trying to make a deal with them."

"Because they have access to ancient magic, and may know how to stop this. Besides, the Queen will not benefit from turning us away. Our worlds are to closely connected, they depend on humans creativity to survive." He pushed aside a bush, and entered a clearing, the trees above so dense the sun was blocked out, In the center of the clearing, a large Willow tree stood "We seek entrance to Albion, and guidance to the Seelie Queen's Court." he placed his hand on Dippers shoulder, "Without explicitly asking for guidance, they could drop us in the middle of the wilds and be done with it."

The ancient tree in front of them seems to open, and the fluttering of wings could be heard behind them, "Stanford Pines, you haven't come back in so long. I was getting bored."

"Hello Mara, will you be our guide to Her Majesty's court?"

"I will, the Queen is expecting you." The small Faerie hovered in front of Dipper, "This one is new, who's this?"

"My Great Nephew, Dipper," Ford replied, "Dipper, this is Mara, a pixie. She is what most of our world think Faeries look like."

"Which is ridiculous, and an oversimplification." Mara muttered, "But now is not the time for conversation, with our worlds on the verge of destruction, we need to hurry. You know the rules, leave your weapons and any iron materials in the "

"Ah, so your world is already coming undone from this," Ford said discarding his weapons.

"Yes, now hurry along." She flew into the tree, the pair following. The path dimly lit by glowing mushrooms, "She opened this path to bring you to her quicker."

"A dire situation indeed." Ford said, "But the haste is appreciated."

They walked in silence a bit longer, before coming to a dead end, Mara knocking on the wood, it fading, Ford and Dipper Stepping forward, Ford kneeling, Dipper copying his uncle, though he couldn't help but look around the room, large stone walls, with vines crawling across it, trees growing through the floor, flickering lights dancing through the room. Dipper could hear music playing in the distance, making Dippers eyes droop, he instead looked ahead, at the curtain covered dais, he could make out the outline of two thrones, only one occupied "My Queen, I ask for your guidance on how to reverse the damage done by the demon Bill Cipher."

"You're forgetting the once human Mabel Pines as well," Her voice was as cold as ice "Your ignorance once again brings the world to the edge of destruction. I will not speak with you, nor do I plan to aid you, Stanford. However, I wish to speak with Dipper. Alone." The queen stood, "Do not speak, simply leave before I chose to turn into a rose bush."

Stanford nodded and stood, squeezing Dippers shoulders and left silently. The only exit closing behind him.

The Queen walked down the steps of the dais, "With thirty years of dimension-hopping I expected him to be smarter. Stand Dipper Pines, we have much to discuss." Dipper stood and looked at her, The Queens pale gold hair was curled and twisted to a half up hairstyle, her blue eyes sharp and unyielding,the loose white dress seemed to shimmer with different colours, she towered over Dipper as she passed him, the scent of the woods after a rainstorm filled the air, he was surprised at how human she looked, "I have no intention of harming you me, you must be starving"

"Why did you make Grunkle Ford leave?" Dipper asked walking beside her.

"Because his arrogance is what led this world into this situation, he thinks he can solve everything when in reality he can't."

"I've made mistakes too," Dipper said, "this was in part my fault, I should have noticed something was off."

"You're a child, and you already know how to accept your wrongdoings, this is why I'm helping you." She sat down at a table laden with food, "I cannot turn Mabel back into a human. However, I can give you a way to bring back her humanity. She will become a useful ally and the way to reverse all of the damage that she and Bill Cipher has caused. It has to be done now though, I can aid you to an extent, hide you from Bill's Gaze and send you to their location, with the means to bring back her humanity, and a way to bring you back here."

"Why are you offering this?" he reached for the food before stopping, remembering his uncles words

"If your world falls, my world will follow, we need belief to sustain us, without it we will perish. I am aiding you because it benefits me, my only condition is that it happens now and we do not tell Ford. Once your mission is done you will come back here and then you can return home. Do you accept?"

Dipper hesitated only for a minute, "My sister will be normal?"

"She will remain a demon, but will regain her humanity, so other than her being a demon, she will be the same."

"Alright, I accept, what do I need to do?"

"The process is very simple all you need to do is shatter this when you're in the same room as her." The queen picked up a small orb from the centre of the table, "It will only work on her though since she was originally human."

"Alright, they won't be able to track me while I'm in there?"

"Only by sight, so if you remain hidden until you find them, you will be fine. Are you ready?"

"I am," Dipper said taking the orb from the Queen's hand, it was warm.

"The orb is also your ticket back." She explained, before flicking her hand, sending dipper away into the heart of the demon's lair.

Once Dipper landed in the empty throne room, he ran to the side and ducked behind one of the pillars, the smell of burning flesh threatening to make him throw up. The screams that echoed throughout the palace making the hair on his arm stand on end, he had to succeed. The orb started getting hotter as his sister's voice echoed down the hallway, "If we move to Russia next I think we should freeze the entire place, see how much cold they can take."

"Freezing an entire country seems rather dull Shooting Star, don't lose your edge now" the pair entered the room, Bill sitting in his throne and Mabel floating beside him.

"Okay, then what would you do? I'm tired of using fire." Mabel said.

"Well, perhaps we could…" Bill stopped as Dipper stepped out of the pillar, "Well look at what we have here Shooting Star. My Puppet returns."

Well, it was now or never, "Well, today is a special day." Dipper said swallowing his nerves, and looking his sister in the eyes, "Happy Birthday Mabel." Dipper said before smashing the orb on the ground at her feet, blinding light filling the room.
