Chapter 4: The Arrival of Euclid and Scalene/ Into the Null Space** (Scibill au/shift falls)
As the swirling vortex of the dimensional rift stabilized, the air around the clearing grew heavy with an otherworldly energy. The team—Stanford, Stanley, Dipper, Mabel, Wendy, and Bill—stood in tense anticipation, unsure of what lay beyond the rift. Suddenly, the vortex pulsed with a bright flash of light, and two new figures emerged from the rift.
The first was a blue triangle-shaped figure, smaller than Bill, with a sharp, angular form and a small, black bow tie. His expression was one of cold calculation, his eyes gleaming with intelligence and an almost clinical detachment. This was **Euclid**, Bill Cipher’s mom.
Beside him floated a larger red triangle, a more imposing presence with a black top hat that hovered just above his head. His gaze was piercing, and his aura radiated an overwhelming sense of power and control. This was **Scalene**, Bill’s other mom.
Stanford's eyes widened as he took in the sight of the two new beings. He instinctively knew who they were—or at least, what they were. "More of them…,” he whispered, stepping back cautiously. “They’re like Bill.”
Bill Cipher’s confident demeanor faltered as he locked eyes with his parents, his usual cocky grin replaced by something that looked uncomfortably close to fear. “Mom. Other mom,” Bill said flatly, his voice betraying the tension in the air. “I didn’t think I’d see you again.”
Euclid floated closer, her eyes narrowing at Bill. “It’s been a long time, son. You’ve been busy, haven’t you? Stirring up chaos across dimensions, escaping the fate of your home world. It seems you’ve gotten… comfortable.”
Scalene hovered beside Euclid, her voice low and commanding. “You’ve managed to survive longer than we expected, Bill. But I suppose you always were more resourceful than the others. Still, that doesn’t excuse what you’ve done—turning your back on us. Fleeing. Escaping the Euclidean Massacre.”
Stanford’s analytical mind kicked into gear as he listened. These two weren’t just more dimensional beings; they were Bill’s parents. And they were far more dangerous than he had anticipated. He glanced at Bill, then back to the new arrivals. “Who are you?” he demanded, trying to mask the fear in his voice. “What do you want with Bill?”
Euclid’s eyes flicked over to Stanford, regarding him with cold disdain. “Ah, the human. Stanford Pines, is it?” Her voice was sharp and precise. “You’ve been quite the nuisance. An interdimensional criminal, dabbling in things you don’t understand. No wonder our son took an interest in you.”
Scalene smirked, her eyes gleaming with malice. “Bill’s muse. How quaint. You’ve caused quite the stir, Stanford. Interfering with our plans. You see, Bill may have abandoned us, but we haven’t forgotten him—or the mess he left behind.”
Stanley, ever the protector, stepped in front of Stanford, his fists clenched. “Hey! You got a problem with my brother, you’ve got a problem with me!”
Bill floated forward, his gaze darkening as he addressed his parents. “Leave them out of this. Whatever you want, you deal with me. I left for a reason. You two went insane—became chaotic, destructive. I didn’t want any part of it.”
Euclid’s expression remained cold. “Chaotic? Perhaps. But we saw the truth, Bill. We saw that order was nothing but a limitation on power. You ran because you were afraid—afraid of what you could become.”
Scalene’s voice dripped with a mixture of disappointment and condescension. “And now, look at you. Playing games with mortals. Hiding in this pitiful dimension with these weaklings.”
Bill clenched his fists, his usual smugness gone. “I’m not like you. I found my own path.”
Stanford, taking in the situation, finally stepped forward. “Whatever your reasons, you’ve come here for something. What do you want with Bill—and with this dimension?”
Scalene turned her gaze back to Stanford, her eyes narrowing. “We’ve come to reclaim what’s ours. Bill has avoided us for long enough, but his little games have finally caught up with him. And as for this dimension…” She trailed off, a wicked smile spreading across her face. “We see potential.”
Euclid nodded in agreement. “The anomalies you’ve been experiencing—those dimensional rifts—are just the beginning. The barriers between worlds are weakening. Soon, this dimension will be consumed by chaos, just as ours was.”
Mabel and Dipper exchanged worried glances, the gravity of the situation sinking in. “What do we do?” Mabel whispered to Dipper, her usual optimism replaced by fear.
Before Dipper could respond, Bill spoke up, his voice full of defiance. “You’re not taking this dimension. You’re not destroying another world.”
Euclid raised an eyebrow. “Oh? And what do you plan to do to stop us?”
Bill’s eyes burned with a fierce determination. “Whatever it takes.”
Stanford, now standing side by side with Bill, nodded. “We’ll fight back. We’ve faced worse before, and we’ll face this too.”
Scalene laughed, her voice echoing through the clearing. “You think you can stop us? How adorable. But very well—let’s see how long your defiance lasts.”
With that, Euclid and Scalene floated back toward the rift, their presence still looming over the group like a dark shadow. “This isn’t over,” Euclid said coldly. “We’ll be watching.”
The rift shimmered, and with a final burst of energy, the two vanished back into the vortex, leaving the group in stunned silence.
Bill hovered in place, his expression unreadable. “They won’t give up,” he said quietly. “They’ll come back. And when they do, they’ll bring everything they’ve got.”
Stanford placed a hand on Bill’s shoulder. “Then we’ll be ready. Whatever they have planned, we’ll face it together.”
The team gathered around, united in their resolve. Gravity Falls had faced countless threats before, but this was unlike anything they had ever encountered. The stakes were higher, the enemies more dangerous—but they weren’t backing down.
As the rift shimmered and closed behind Euclid and Scalene, the air in the clearing felt heavy. The looming threat of Bill Cipher's parents—ancient, powerful beings—cast a shadow over the group. The danger wasn’t just a personal conflict for Bill anymore. It was a battle for the survival of their entire dimension.
Stanford Pines stood alongside Bill, his mind racing. The return of Bill’s parents had complicated things immensely. If Euclid and Scalene truly intended to unleash chaos on Gravity Falls, it meant the dimensional fabric itself was in danger of collapsing.
“We need a plan,” Stanford finally said, breaking the tense silence. His voice was steady, but there was no mistaking the urgency behind it. “Those two won’t stop until they’ve torn this world apart.”
Stanley, arms crossed and still simmering with anger, spoke up. “You heard ‘em—they want to bring chaos here like they did to their own world. We need to find a way to stop them, once and for all.”
Mabel stepped forward, her eyes wide but determined. “They seemed really powerful, though. How do we fight something like that?”
Dipper, who had been staring at the now-closed rift, turned to face the group. “We need to learn more about them—what they are, what they’re capable of. If they’re like Bill, maybe there’s something in the journals or in the portal notes that can help us.”
Bill, who had been uncharacteristically quiet, finally spoke. “You’re right, kid.” His voice was tense, devoid of its usual smugness. “But don’t get your hopes up. Euclid and Scalene aren’t like me—they’re far worse. They embraced the chaos of the multiverse in ways even I wouldn’t. And they’ve had centuries to grow stronger.”
Stanford frowned. “What exactly are they capable of? You need to tell us everything.”
Bill hesitated. For the first time, the trickster demon seemed genuinely unsure. “They don’t just break worlds—they twist them. Euclid’s a master of dimensional mathematics. He can calculate the structural weaknesses of a universe and tear it apart from the inside. And Scalene… she’s pure entropy. Anything she touches unravels. Order, stability—it all crumbles in her presence.”
Wendy, who had been silently absorbing the conversation, finally spoke. “Sounds like we’re going to need more than gadgets and journals to handle this.”
McGucket, who had been scribbling furiously in his notebook, suddenly looked up. “I reckon we might need to reinforce the dimensional barriers themselves! I’ve been workin’ on theories fer how to stabilize dimensional rifts—if we can reinforce Gravity Falls, maybe we can keep their influence out!”
Stanford nodded, intrigued. “That might work, but we’ll need to modify the technology we have. The portal tech I’ve built can detect dimensional weaknesses, but we need something stronger to contain or repel them.”
Bill hovered slightly above the group, arms crossed. “If you’re thinking of trying to fight them on a scientific front, you’re gonna need more than just machinery. They’re beings of pure chaos—unpredictable, uncontrollable. But… I might have something that could help. It’s risky, though.”
Dipper raised an eyebrow. “Risky? Coming from you, that sounds... concerning.”
Bill gave a half-smile, though it didn’t reach his eyes. “Yeah, kid. It’s concerning. But desperate times, right? There’s a place in the multiverse—a kind of ‘null space’ between dimensions. It’s where I learned a lot of my tricks. There might be something there we can use to counteract Euclid and Scalene’s powers. But accessing it? Not easy.”
Stanford’s eyes lit up. “Null space… That could be a breakthrough. If we can tap into that, we might find something—some energy or force—that can oppose their chaos.”
Stanley, still wary of Bill, chimed in. “And how do we know this isn’t another one of your tricks, huh?”
Bill floated closer to Stanley, his expression serious. “Trust me, Sixer’s brother—I want them gone just as much as you do. You think I liked running from them? No. They want to tear this place apart, and I like this dimension. It’s fun. So, if you’re asking if I’m in this for myself—yeah, I am. But that also means we have a common goal.”
Stanford turned to the group. “We don’t have much time. Euclid and Scalene are preparing for their next move. If we’re going to stop them, we need to start gathering resources—both from here and from wherever this null space is.”
Mabel pumped her fist in the air. “Let’s do this! We’ve faced monsters, possessed gnomes, and time travelers. A couple of triangle demons? We’ve got this!”
Dipper, still thoughtful, nodded. “We’ll need to be smart about it. We should divide into teams—some of us should work on reinforcing the dimensional barriers here, and the rest of us will explore this null space Bill mentioned.”
Stanford smiled at Dipper’s initiative. “Good thinking, Dipper. I’ll stay here and work with McGucket on the dimensional barrier technology. Bill, you’ll lead the expedition to null space.”
Bill grinned, his confidence returning. “You got it, Sixer.”
Wendy stepped forward. “I’ll go with Bill. Someone’s got to keep an eye on him, right?”
Dipper, looking between Bill and Wendy, raised his hand. “I’ll go too. If there’s something out there that can help us stop Euclid and Scalene, I want to be part of finding it.”
Stanley clapped a hand on Mabel’s shoulder. “Looks like the rest of us will stick here and make sure Gravity Falls doesn’t fall apart while you’re gone.”
The team agreed, each taking their roles seriously. With the clock ticking, they had no choice but to trust in Bill’s knowledge and Stanford’s technology. Euclid and Scalene would return, and when they did, it would be an all-out war for the fate of the dimension.
As the group dispersed to prepare for their tasks, the sense of urgency hung thick in the air. The fate of Gravity Falls—and perhaps the multiverse itself—rested on their shoulders. The battle against chaos was just beginning.
The next morning, the team gathered outside the Mystery Shack. The sky was unusually cloudy, an eerie reflection of the looming threat. Bill, floating lazily in the air, was back to his usual smirk, though his eyes held a flicker of seriousness.
Dipper, Wendy, and Bill stood together, ready to embark on the mission into null space. Mabel, Stanley, and McGucket were already setting up the equipment to work with Stanford on the dimensional barriers, the hum of machinery filling the air.
Stanford approached Dipper and handed him a small, cylindrical device. “This is a dimensional tether. It’ll keep you anchored to our reality when you’re inside null space. Use it to find your way back. And be careful—null space is unpredictable. It doesn’t follow any of the normal laws of physics.”
Dipper nodded, slipping the device into his jacket pocket. “We’ll be careful, Grunkle Ford. Just… keep this place safe until we get back.”
Stanford patted him on the shoulder, glancing over at Bill. “You’re going to need him in there. Whatever happens, trust your instincts.”
Stanley, standing beside Mabel, raised an eyebrow at Bill. “Don’t get any ideas, Cipher. If you mess this up, I’ll make sure you regret it.”
Bill’s eye rolled dramatically. “Relax, Sixer’s brother. I’m not looking to double-cross anyone. We’re all in this together now.” His expression grew a little more serious as he turned to Dipper and Wendy. “You two ready? Null space isn’t exactly a vacation spot.”
Wendy slung her axe over her shoulder and cracked her knuckles. “I’ve been ready for weirder stuff since the zombie invasion. Let’s go.”
Dipper nodded. “Let’s do this.”
With that, Bill raised his hands, summoning a shimmering blue portal in the air. The edges crackled with energy, and the vortex swirled with unnatural force. “This’ll take us straight into null space. Just stick close to me, and don’t touch anything unless I say it’s safe.”
Dipper and Wendy exchanged a glance, then followed Bill into the portal. The world warped around them, and they were pulled into the strange, chaotic realm of null space.
The moment they crossed into null space, the difference was staggering. The landscape was a surreal, shifting expanse of shapes, colors, and dimensions that defied logic. Objects floated in and out of existence, and gravity seemed to bend and twist in random directions. The sky was a swirling mass of purples and reds, with flashes of green lightning arcing across the horizon.
Wendy whistled, looking around in awe. “Okay, this is definitely weirder than the time I saw a gnome spit up rainbows.”
Dipper held tightly to the dimensional tether, his eyes wide as he tried to make sense of the surroundings. “This place… it’s like nothing I’ve ever seen. How do we even know where to go?”
Bill, floating above them, looked unusually focused. “Null space is a place between places—where the rules don’t apply. But there are *paths* here if you know how to look for them. We’re looking for a particular pocket of energy. It’s what Euclid and Scalene used to fuel their chaos back in our home dimension. If we can harness it, we can counteract their power.”
As they ventured deeper into the strange landscape, they encountered a series of floating geometric shapes—pyramids, cubes, and fractals—that shimmered and shifted as they passed. Occasionally, the ground itself would tilt, forcing them to adjust their footing or risk falling into an endless void.
Wendy glanced at Bill. “So, what’s the deal with your parents? You made it sound like they used to be normal. What happened to them?”
Bill’s eye darkened slightly as he floated along beside them. “They weren’t always like this. When I was younger, our dimension was a place of logic, structure. Euclid was obsessed with mathematics, and Scalene was focused on maintaining balance. But somewhere along the way, they became obsessed with the idea of *absolute* power. They started experimenting with chaos energy, and it changed them.”
He paused, his voice quieter. “I tried to stop them. But by then, they were too far gone. They wanted to destroy everything to remake it in their image. So I ran.”
Dipper frowned, trying to piece it together. “You didn’t destroy your own dimension, did you? Your parents did.”
Bill nodded. “They unleashed the chaos, and I barely escaped. They were too powerful to stop, so I came here. And now… well, they’ve found me. And if they have their way, this dimension will be next.”
Wendy raised an eyebrow. “So you’ve been running from them all this time?”
Bill’s eye narrowed. “I wasn’t *running*. I was surviving. There’s a difference.”
Before Wendy could reply, the ground beneath them shifted again, and a towering structure appeared in the distance. It looked like an impossible construction—a series of interlocking triangles and spirals that defied geometry, suspended in mid-air.
Bill stopped, his expression turning grim. “There it is. That’s the energy source we need to tap into. But getting close to it? That’s going to be the tricky part.”
Dipper stared at the structure. “What do you mean?”
Bill pointed at the shimmering shape in the sky. “That thing’s surrounded by chaos energy. One wrong move, and it could tear you apart—literally. You’d be unmade, scattered across the multiverse.”
Wendy smirked, gripping her axe tightly. “Sounds fun. What’s the plan?”
Bill floated closer to the structure, his eye narrowing in concentration. “You two will need to distract it.”
Dipper blinked. “Distract *what*, exactly?”
Before Bill could answer, the structure began to shift, and a massive form emerged from within it. It was an enormous, glowing creature made of pure chaos energy, its body constantly changing shape—one moment it was a serpentine figure, the next it was a mass of twisting limbs and eyes. The very air around it crackled with instability.
Bill grinned, his confidence returning. “That. You two keep it busy while I extract the energy we need. Try not to get yourselves erased from existence.”
Wendy gave a confident nod, while Dipper swallowed nervously. “No pressure,” Dipper muttered.
The creature let out a roar, its voice echoing through the distorted space. Wendy raised her axe, ready for a fight, and Dipper held onto the dimensional tether tightly.
“Alright, let’s do this!” Wendy shouted, charging toward the creature.
As the battle began, Bill floated toward the structure, his hands glowing as he began the delicate process of extracting the chaotic energy they needed. The next step in their journey was underway, and the fate of Gravity Falls hung in the balance.
Back at the Mystery Shack, Stanford and Mabel worked feverishly on the dimensional barrier equipment. The machine they were assembling was a complex array of circuits and energy nodes designed to reinforce the dimensional integrity of Gravity Falls. The atmosphere was tense, with everyone focused on their respective tasks.
Stanley, ever the hands-on guy, was busy making final adjustments. “Mabel, hand me that flux regulator,” he said, pointing to a small, intricate device on the workbench.
Mabel, carefully picking up the component, noticed a peculiar-looking suit hanging nearby. It was Stanley’s old space suit, which had been modified with various gadgets over the years. “Hey, Grunkle Stan, what’s this suit for again?”
Stanley glanced over his shoulder. “That old thing? It’s mostly for dealing with environmental anomalies. Figured it’d be good to have just in case. But don’t mess with it right now, Mabel. We’re on a tight schedule.”
Mabel, her curiosity piqued, couldn’t resist. “Just taking a closer look.” As she fiddled with the suit’s controls, a series of unexpected lights began flashing, and the suit emitted a low hum.
Stanley’s eyes widened. “Wait, Mabel, don’t—”
Before anyone could react, the suit’s built-in portal device activated, creating a shimmering vortex. Mabel, still inside the suit and unaware of the danger, was pulled into the rift along with Stanford, who had been trying to reach her.
Stanley’s shouts of alarm echoed as the portal closed behind them, leaving him alone in the workshop. “No, no, no! Mabel! Ford!”
Stanford and Mabel tumbled through the chaotic landscape of null space, their surroundings a dizzying blur of colors and shifting shapes. They landed with a thud on the uneven ground, disoriented but relatively unharmed.
Stanford groaned as he picked himself up. “Mabel! Are you alright?”
Mabel, dusting herself off, looked around in awe. “Whoa… where are we?”
Stanford, already adjusting his gear and scanning the area, replied, “We’re in null space. It’s an unstable, dimension-spanning void between realities. Not exactly where we intended to be.”
Mabel looked around at the swirling, ever-changing scenery. “This is incredible! But also kind of terrifying.”
Stanford nodded, his expression serious. “We need to find a way back to the Shack and fast. This place is unpredictable and dangerous. The suit’s portal must have malfunctioned and brought us here.”
As they began to move cautiously, trying to get their bearings, they noticed a distant, glowing structure in the landscape. It looked like a massive, geometric formation—a structure similar to the one Dipper, Wendy, and Bill were heading toward.
Mabel pointed to it. “That looks like it could be important. Do you think it’s related to what’s going on with Bill and the others?”
Stanford squinted at the structure, his mind racing. “It’s possible. We might be able to find some clues or even help them if we can get closer.”
They started making their way toward the structure, but the chaotic nature of null space made progress slow and treacherous. Every step seemed to alter the environment around them, causing the ground to shift and gravity to fluctuate unpredictably.
**Meanwhile, in the Battle Against the Chaos Creature**
Bill and Wendy were locked in a fierce battle with the chaotic creature, which continued to shift and morph with each passing moment. Dipper fought alongside Wendy, using a combination of tactics and bravery to keep the creature at bay.
Bill floated above them, concentrating on extracting the chaotic energy from the massive structure. “Hang in there! I’m almost done!”
Suddenly, a rift opened nearby, and Stanford and Mabel stumbled out, landing clumsily on the chaotic ground. The sudden appearance of the newcomers caught everyone’s attention.
Bill’s eye widened in shock. “Ford! Mabel! What are you doing here?”
Stanford, dusting himself off and looking around, replied, “We were pulled into null space by a malfunctioning portal device. We need to get back, but we saw the structure and thought it might help.”
Mabel, looking at the chaotic creature, added, “This place is wild! But it looks like you guys could use some help.”
Dipper, recognizing the gravity of the situation, rushed over. “We could definitely use some extra hands. The creature’s tough, and we’re not sure how long Bill can keep it distracted.”
Stanford quickly assessed the situation. “Alright, Mabel, stay close and follow my lead. We need to help Bill finish what he started. Once we’ve dealt with this creature, we can find a way back.”
With renewed determination, the group coordinated their efforts. Mabel used her resourcefulness to create distractions and provide support, while Stanford used his knowledge of dimensional theory to help stabilize the environment around them.
Bill, concentrating on the energy extraction, glanced at Stanford with a mix of relief and frustration. “I didn’t expect you guys to show up here. But since you’re here, let’s get this done.”
As the battle continued, the combined efforts of the group began to turn the tide. The chaotic creature, overwhelmed by their coordinated attacks and Bill’s extraction efforts, started to weaken.
Finally, with one last surge of energy, Bill managed to extract the chaotic essence from the structure, causing the creature to dissipate into the void.
Bill floated down, looking exhausted but satisfied. “We did it. The energy we needed is secured. Now we just need to get back to Gravity Falls and reinforce the dimensional barriers.”
Stanford nodded, his expression focused. “We’ve still got work to do. But with this energy, we might have a chance to stop Euclid and Scalene.”
With the chaotic creature defeated and the critical energy secured, the group prepared to return to the Mystery Shack. The journey had been perilous, but they had succeeded in their first step toward confronting the looming threat.
With the chaotic creature defeated and the critical energy extracted, the group began to prepare for their return to Gravity Falls. Bill Cipher, floating nearby, was still visibly drained from the intense battle.
As everyone gathered their things and began to regroup, Bill’s eye narrowed slightly, and he suddenly seemed preoccupied. “Man, I didn’t realize how hungry I was.”
Dipper, wiping sweat from his brow, looked up. “Hungry? Now? We’ve got bigger things to worry about.”
Bill waved him off with a dismissive gesture. “I can’t help it. It’s been ages since I’ve had a proper meal. And this place? Well, let’s just say it’s not exactly easy to find a good snack.”
As if on cue, Bill’s gaze fell on the remains of the chaotic creature. The creature’s body had dissolved into a floating, shifting mass of chaotic energy, but a few remnants still floated around. Bill’s eye gleamed with an odd mixture of curiosity and hunger.
Without a second thought, Bill extended his mouth—an odd, distorted eye-mouth—toward the chaotic energy. He began to “consume” the energy, his mouth opening wide and swirling as he devoured the remnants of the creature. The process was unsettling to watch, as the chaos energy seemed to vanish into Bill’s form.
Stanford, observing with a mixture of horror and disbelief, stared. “Bill, what are you doing? That’s not—”
Before he could finish, Bill let out a satisfied sigh and then, quite unexpectedly, burped loudly. The burp echoed across the chaotic landscape, and a faint shimmer of leftover chaotic energy dispersed into the void.
Mabel, watching with a mix of amusement and disgust, chuckled. “Well, that’s one way to deal with leftovers.”
Bill floated back to the group, looking considerably more content. “Hey, don’t knock it until you’ve tried it. I was starving, and that chaos beast was surprisingly filling.”
Wendy, trying to suppress a laugh, shook her head. “Man, you’re something else, Bill.”
Dipper, still trying to process what he had just seen, sighed. “At least you’re not hungry anymore. Let’s just get back to the Shack and reinforce those barriers.”
Stanford, though still uneasy about Bill’s choice of “snack,” nodded in agreement. “We need to return and prepare for the next phase. Euclid and Scalene are still out there, and we have a lot of work ahead of us.”
Bill nodded, his previous hunger now sated. “Alright, let’s head back. I’ll open the portal.”
With the chaotic creature’s remnants consumed and the group’s spirits lifted by their victory (and Bill’s unexpected burp), Bill floated up and began to conjure a new portal to take them back to Gravity Falls.
As the portal shimmered into existence, the group stepped through one by one, returning to the familiar, albeit still strange, reality of the Mystery Shack.
**Back at the Mystery Shack**
Upon their return, the group was greeted by a worried Stanley, who had been anxiously waiting for their return. His face lit up with relief when he saw them emerge from the portal.
“There you are! I was about to lose my mind,” Stanley exclaimed. “What happened? Are you alright?”
Mabel grinned, stepping forward. “We’re all good! Bill just had a rather… unconventional snack, but other than that, everything’s fine.”
Stanley raised an eyebrow, looking at Bill with a mixture of skepticism and disbelief. “I see. Well, I’m just glad you’re back.”
Stanford immediately got to work with McGucket and the team on reinforcing the dimensional barriers. The chaotic energy extracted from null space was integrated into the equipment, and the complex machinery began to hum with renewed power.
Dipper and Mabel helped out, setting up additional defenses and ensuring everything was in place for the coming confrontation with Euclid and Scalene.
As the preparations continued, the team knew they had only taken the first steps in a long and arduous battle. But with their combined efforts and newfound knowledge, they were ready to face whatever came next.
