Every hundred years a Fae moon rises, and the human child born under the brightest rays is chosen.

Chosen? Chosen for what?

Simple... They're chosen for the Fae. And, of course, a Fae child must replace the human, a Fae born under the same moon. Equals and opposites in every right. A mortal, weak, pathetic, dumb human, replaced by an immortal, strong, superb, amazing Fae. Destined to live each other's lives.

Well, Stanley's life seems to suck pretty badly. Wonder what mine's like...

One eye. Two eyes. Four eyes. Six eyes...

Green eyes illuminated the small room inside of the hospital. The hushed breeze stole through the area, bringing the human's scent to her nostrils. Oculos caught a whiff of the One, the one she was supposed to gather. There hadn't been a gathering in a hundred years, and she was honored to be the one to carry this out.

The One lay in his bed, sleeping. The night air resting on top of him, more so than the small blanket around him. Oculos crept up on the infant, and adjusted the bundle in her own arms.

She laid the Fae child next to the human, and watched with silent and hungry eyes as the blurry and dark features of the Fae began to take on that of the other child. Both were only a day old. Both had been born under the Fae full moon. Both had been chosen.

A moment of silence later, and Oculos was satisfied with the other Fae's morphing. She reached her long, wispy fingers out, and wrapped them around the human child. The young boy's eyes flew open, and he stared at her. Oculos froze, and her eyes stared into his. Please don't cry...

The infant, so young, so small, so delicate, wrapped his fingers around one that she stretched out to him. They gripped it firmly, and Oculos saw something strange.

This human child had six fingers. That wasn't the normal amount... probably... This child was strange. Unusual. An anomaly. Deformed...

Perfect.

Stan watched the portal spin out of existence again. But this time instead of static, the person he'd wanted to see stepped out.

Stanford was dressed entirely in black, his face covered by a mask, a large gun strapped to his back. Stan could feel his grip on his form start to slip, and he hoped he could regain control over his emotions until he could explain to Dipper and Mabel. Stanford was lucky. Stanford didn't really need to worry about something like this.

Stanford stepped towards Stan, who stepped closer to him. Dipper's voice broke through the silence, and the young boy asked, "Who is that?" Stan glanced over at him, his green eyes shining at him. "The Author of the Journals... My... Well, I don't really know how our relationship works, but he's basically my twin... Sorta... It's complicated."

Stanford's mask literally dissolved away, into a pale cloud of smoke that disappeared almost instantly, revealing a face almost identical to Stan's. He looked a bit more classy though, which was saying something, as Stan normally went around in suits. There was an air around him, like he was royalty or something, and it seemed to fill the room. His coat had silver embroidery around the cuffs, which seemed to flow as he moved, like he had a river trapped on his garment.

Stanford stepped down to Stan, who gave him a smile. His face remained emotionless, and then Stan said, "It's been a while... Hasn't it?"

"You aren't showing your eyes." Was all that Stanford said. Stan blinked hard, then raised a hand to his face. "Yeah... It freaks people out." He explained, shrugging his shoulders. "So... How's your past thirty years been?"

Stanford half sighed, scanning Stan's form. "Well, it's been... eyeopening. What about yours?" Stan hadn't noticed Ford's British-sounding accent last time, or at least, he hadn't remembered it, but now it was quite obvious. He shifted awkwardly, feeling like a student under scrutiny. "Uh... It's been good... Met our niece and nephew... Started a tourist trap..."

A nod came from Stanford, and Stan sighed loudly. "Can we cut it with the chit-chat? I want to talk to you!" Ford rolled his eyes, then said in a low voice, "That's fascinating. Has it ever occurred to you that you might not be the center of the multiverse? Or are you just like everyone else in your species?" He folded his arms across his chest, and glared at Stan, who stared back in silent shock.

"Honestly, you'd think you were all the Axolotl or something," Ford muttered, glaring off at the ground to his left, Stan felt his mouth open, but no sounds or words came out. He felt his grip on his form begin to slip, whether it was from confusion or anger. Stanford seemed to find that particular patch of rock to be rather interesting, as he did nothing but stare at it for a good minute.

Stan's hands, thankfully still humanlike, clenched into fists. "Think I was like what?!" He demanded, taking a strong step towards Ford, who still paid him no attention. "Who do you think you are?! I'm the proud one?"

Ford glanced briefly at Stan's face, then a small grin spread across his own. "It worked... You're showing two more." He rubbed his right pointer finger across his eyebrows, and Stan stared at him in confusion. "What are you talking..."

It hit Stan like a hurricane. The reason he could suddenly see so much better? He was now opening four eyes with every blink, Ford had manipulated him into showing off more of his true nature. Stan wasn't too sure that he liked that...

At the tender age of six human years old, Stanford was sent off to school. Well... not really. Because he was the only human in the entire dimension (that they knew of at least) he had been raised inside of the castle walls, which had the Royal Academy on the grounds. So when he was six he was allowed to go to the academy, even though he wasn't enrolled there.

He had a private tutor, who basically just did nothing while he read quietly, and he excelled in all of his subjects, yet whenever he got yet another A+ he'd always ask if he was ready to go to school, with the other children.

The tutors, superintendents, counts, and even the Princess herself all tried to explain to him that he wasn't ready. Of course he was too smart for that. "But everyone else my age is going." he reasoned, doing his best to remain emotionless and simply watch the Princess' eight blue eyes staring down at him. "I just want to be... I just want to see the world. I promise I'll do everything right. I'll come back straight away. I'll do whatever you want me to! Please?"

The Princess closed her eyes, and her slender form seemed to destabilize a tiny bit. He shrank back a little bit. When a Fae lost grip on their form it was either dangerous, or, at the very least, terrifying. He had tried to stay on everyone's good side, but every now and then his curiosity got the best of him and everyone else.

"Stanford." Her voice called out, and it was deeper and more... pure than before. He knew that he was in trouble. The Princess drew herself up to nearly her full height, towering over the small boy. Her eyes opened, and instead of eight she showed her ninth and tenth as well. She was ticked off. She bent down towards him, her form appearing like a bent tube. Her blue eyes illuminated the small boy's scared face.

He closed his own eyes and waited for a lecture that was sure to be coming. The Princess seemed to melt back into herself, a sympathetic look on her pale black face. "Stanford..." she repeated, sounding more motherly that time, and the small human opened his eyes again, looking at her smaller form. She was now the size of a regular human adult, and he bit his lip. "Your... Your highness..." he replied, and she sighed slightly.

"I have been unfair to you. Every child should be given a chance to go to the Academy. I used to pride myself in how well I kept that statement..." She closed her eyes, then opened them again. She held her hand out to the small boy, and he took a step forward towards her, reaching his own pale hand out and resting it on her black one, which she wrapped around his. "Now I see that I have not kept it well at all. From now on all humans will be allowed to attend."

Stanford couldn't help but blurt out, "Are there more of me?"

There was never a true answer to his question. At least, not for him right then.

"You thought my life was so hard? Try living your life!"

It was difficult to keep one set of eyes shut. Stanford didn't seem too pleased with what Stan was trying to do, but Stan didn't want to freak the kids out any more than necessary. Stan folded his arms, tired of Stanford writing off his time in the human world. Once Stan had said that Stanford pulled his hands into fists. "Oh yes, I'm sure it was so hard to live in a place where you were supernaturally gifted. Making you stand out among your peers. I'm sure that not being seen as stupid was so difficult."

Before Stan could snap anything back, Mabel's voice called out, "What on earth is going on? Who are you? Why is Grunkle Stan glowing?!"

Stanford's eyes snapped over to the girl, and his eyes widened exponentially. "A human female..." He muttered, just loudly enough for Stan to hear him. "I've never met another human before..." Stanford looked at Stan for a brief second, then stepped towards the small group. "And there's the male... two of them. A pre-adolescent and a... well... Whatever this one is."

He sped walked over to the three humans, and Stan turned to watch him as he passed. Stanford knelt in front of Mabel, tilting his head to the ground as a sign of respect. "It is an honor to meet you aanzien." He held a hand palm up to her, and she placed her own hand timidly on top of it. "Uh... Nice to meet you too... I'm Mabel."

Stanford looked up at her, their eyes meeting. "My name is Stanford. Mabel is a lovely name if I can say... How old are you? What is your diet like? How do you function with the nature around you? Do you live with your parents?" Mabel blinked at his rapid-fire questions, then mumbled, "Uh... Do you not know?" Stanford shook his head, "I lived in a controlled environment. One that was suited for another species. Is it true that you can breed with any type person in your species? Of the opposite sex that is. Fae..."

Mabel's already pinkish cheeks turned a soft red, along with her ears. Stanford tilted his head in confusion, and asked, "Are you alright aanzien- Mabel. Are you alright Mabel?"

"She'll be fine." Stan said, taking a step forward and whacking the back of Stanford's head lightly with the back of his hand, "That's just not a question you ask a kid- Ahh!"

Before Stan could finish, Stanford leaped to his feet, spun around, and grabbed Stan's still outstretched wrist. He twisted his arm around, and brought Stan to the ground, placing a booted foot on his jacket-covered back. Stan let out a gasp of pain, and Stanford scoffed at him. "You're a pathetic Fae you know. A wicht could best you."

"Don't hurt him!" Mabel cried, dashing up to Stanford and grabbing his left arm. "Please! What are you talking about?" Stanford looked over at the girl, noticing her terrified eyes. "My aanzien," he said, his eyes being drawn to her hand that was gripping him. "I don't believe it is possible for me to hurt him... too much. He is the lucky one in this situation."

Mabel's terror turned into fury. "He's an old guy Mr. Stanford! He's gonna get hurt! Look at him..." Stanford did what she said, noticing Stan's teeth getting grit together. "My aanzien, any pain he feels is purely psychological. He's not even a tenth into his life cycle. Fae live to reach their thousandth..." Mabel sent him a confused look, and he muttered, "Of course he didn't tell you... You see... Stanley, or should I say, Gekozen, isn't a human. He's a Fae. A changeling. The only reason he looks like he's a human..."

His face turned bitter, and he removed his foot off of Stan. "Is because he replaced me."

"Come on! I'm human and I can do this! Just twenty more!"

So... Stanley had no idea why he had brought his 'brother' back. Stanford had been sealed off in the Multiverse (and/or the Fae world) for another thirty years, and claimed he was working on defeating an unnamed threat. Now that he was there he immediately started training Stan. Right now he was being forced to run. Run like he was being chased by something. It didn't help that Stanford (or Ford, or Mensen, as he said the others called him) was running ahead of him. The worst part was that Ford was in full changeling armor, and Stan was just in a t-shirt and pants. How was the guy so fast?

"Can... We... Slow down... Just a bit?" Stan puffed out, and Ford looked back at him a confused look on his face. "Do you think that they'll let you do that on the battlefield?" He shouted, and Stan groaned. "There's not gonna be a battlefield..." He snapped, and realized that he had stopped moving. Ford himself seemed to notice this too, and he came to a screeching halt, spinning around and into a kneel.

"Oh, there will be a battlefield sometime in your life. Maybe my own, but who knows. If Bill's stubbornness is any indication... And if I die before he gets into this dimension he almost certainly will in Aanzien's or her brother's."

Stan huffed, then asked with his arms crossed. "Why do you call her 'and-zeen'? Her name is Mabel." Ford froze, then said, "Well, she's the first human... Do you... Of course you don't know what that means." He sighed, then sat down cross-legged on the ground. "I had to learn a lot of Old Fae, aanzien means respect. It's the title I have chosen to call her."

He sighed again, then said quietly, "I grew up where I was the only one like me. Everyone treated me like I was stupid. Because I was human. I would train for hours to do the same things that everyone else could... but when it came to actually performing..." He rubbed his left arm and stared at the grass around them, then said quietly, "I just couldn't do it. And it drives me insane to see you have what I always wanted, and to do nothing with it."

There was a moment of silence, then Stan said, "So... You know a bunch of cool fighting moves... for no real reason?" Ford's eyes flew up and met his, and he bit his lip as Stan's glowed with a dull light.

"Not entirely no reason. I can teach you." He said, a bit of hope sliding into his voice. "But I'm going to need you to cooperate. I know it may seem pointless right now, but what I have you doing has a reason.

"You'll just have to find it."

Hi guys!

A guest sent me the prompt for this a while ago. I quickly found out a lot about the NeverHuman AU (which is totally awesome, definitely would recommend) and decided to take my own spin on it.

In the classic AU Stan and Ford grow up together, only for Stan to find out he's not human while he lives in Gravity Falls. In this one... No. Stan lives with Filbrick and Caryn, and Ford gets raised by the Changelings. The portal is the bridge between worlds, and Stan somehow makes it... stop working for a while, leaving Ford on the other side. Good thing Ford was sort of obsessed with the portal, and wrote out all the instructions.

I got all of the Fae language stuff from WordHippo. I literally just looked up Dutch words (because Changeling lore comes from Europe, and that's different enough from English that it makes sense).

Mabel has a fan now. Just wait till he finds out he's her uncle. And that he has a family. A family who will (probably) love and accept him. And find all of his knowledge of Fae and the Multiverse fascinating (cough -Dipper- cough cough). He's probably going to be so... happy and overwhelmed.

I hope you guys enjoyed this. If any of you have any more prompts don't be afraid to send them to me! I actually have one that I'm planning out right now. I'll try to get to those as soon as possible (if I really really like it I get to it like, instantly). Have a great rest of your day!
