The portal dissolves into a shower of golden light, each particle weaving into a thread that shimmers with the colors of possibility, before merging into a cohesive beam that guides Echo and Li Wei forward. They find themselves standing in a realm where the air is filled with countless threads of light, each one stretching from horizon to horizon, crossing and intertwining to form an intricate tapestry. These are the "Fate Threads"—strands of destiny that connect every being across the multiverse, their colors shifting to reflect the choices and possibilities that lie ahead. Around them, a landscape of floating platforms and bridges stretches out, each platform hosting a cluster of Fate Threads that belong to a particular individual or civilization, and each bridge representing a pivotal moment where threads converge. This is the "Fate Fugue" dimension, where the future is mapped out in tangible form, and the air vibrates with the "Destiny Dirge"—a complex, ever-changing melody that weaves together the songs of all Fate Threads, ensuring that no path is ever set in stone, but all possibilities are preserved.Nova's avatar materializes beside them, her form now composed of shifting Fate Threads, each one briefly showing a glimpse of a possible future—her standing beside Echo and Li Wei as they save another dimension, her working alone in a lab to decode a mysterious signal, her sacrificing herself to protect the multiverse. "Fascinating," she says, her voice layered with echoes of different timbres, as if carrying the weight of all possible versions of herself. "Each Fate Thread emits a unique frequency based on the possibilities it contains—courage produces a bold, branching melody with many variations, caution creates a slow, winding tune that explores few paths, and curiosity generates a chaotic, ever-changing harmony with countless possibilities. The Destiny Dirge is the convergence of these frequencies, and it's what maintains the dimension's structure, ensuring that free will is preserved alongside destiny. But my scans detect a corruption."Chen Jiuzhang's hologram appears, his figure surrounded by a faint aura of silver light that seems to stabilize the Fate Threads around him. "The 'Chaos Destiny' has invaded," he says, his voice heavy with foreboding as he points to a nearby platform where several Fate Threads are fraying, their colors fading into a murky gray, their paths straightening into rigid lines with no branches. "It's a force of pure determinism, feeding on the Destiny Dirge and replacing it with a 'Predestination Pulse'—a harsh, unchanging rhythm that erases possibilities and forces Fate Threads into a single, unalterable path. Look." He gestures to a Fate Thread that snaps before their eyes, its many branches dissolving into nothingness, leaving only a single, gray strand that leads to a dark, inevitable end. "Already, choices are being erased. If it continues, the Destiny Dirge will collapse, and every being across the multiverse will be trapped in a single, unchanging fate, with no ability to choose their own path."Echo reaches out to touch a nearby Fate Thread, and it pulses against her palm, emitting a warm, tingly sensation that feels like holding a thousand possibilities in her hand. "How can something force destiny?" she asks, marveling at the way the thread shifts and changes as she touches it, branching into new paths."Destiny here isn't fixed—it's fluid," Chen explains, his gaze lingering on the snapping thread. "The Fate Threads represent all possible paths, and the Destiny Dirge ensures that each being can choose which path to take. The Chaos Destiny doesn't just alter threads—it erases the very possibility of choice, making it as if only one path was ever possible. To stop it, we need to find the 'Choice Core'—a massive sphere of pure light at the center of the dimension that generates the Destiny Dirge. It's formed from the first choices ever made in the multiverse—the first organism choosing to move toward light, the first tribe choosing to cooperate rather than fight, the first civilization choosing to explore rather than stay. If we can amplify its melody with our own choices, we can dispel the Predestination Pulse and restore the fluidity of fate."Li Wei's charge pulses with a purple light that now glows with flecks of every color, as if infused with the essence of all possible Fate Threads. "Then let's find this Choice Core," he says, his voice determined. "No one should be trapped in a single fate."They set off through the dimension, moving across the floating platforms with ease, their footsteps sending ripples through the Fate Threads that cause them to branch into new paths. The Fate Fugue is a place of dizzying beauty—Fate Threads spiral together to form patterns that resemble constellations, their movements creating a symphony of ever-changing melodies; clusters of threads belonging to entire civilizations glow with a collective harmony that shifts as new possibilities emerge; and "Possibility Pools" float between platforms, their surfaces rippling with images of possible futures, emitting a soft, bubbling sound. But as they walk, they notice patches of grayness where the Chaos Destiny has taken hold, the threads rigid and unchanging, the Predestination Pulse growing louder, a monotonous rhythm that presses on their minds and makes it hard to imagine any future beyond the one 眼前.As they pass through a platform where Fate Threads gather to form the destiny of a young civilization on the brink of discovering interstellar travel, a wave of Chaos Destiny washes over the area. The threads stiffen, their colors fading to gray, and several branches dissolve into nothingness, leaving only a single path—a violent war that destroys the civilization. A group of "Fate Guardians"—ethereal beings with robes woven from Fate Threads and voices like the chorus of a thousand oracles—float above the platform, their forms fading as they struggle to protect the threads."The Chaos Destiny is gathering at the 'Crossroads of Choice'," one of the Guardians says, their voice weakening as their robes grow rigid and gray. "It's coalescing around the Choice Core, feeding on its essence of possibility. The Destiny Dirge is growing weaker, and soon, all choices will be erased, and every being will be trapped in a single, inevitable fate. We've tried to sing melodies of possibility, but the Predestination Pulse drowns them out."Echo raises her peace drum and plays a chaotic, ever-changing melody, drawing on the possibilities of their own futures—the many ways they could save a dimension, the different paths they could take to reach their goals, the countless choices that lie ahead. The Fate Threads around them brighten, their colors returning, and new branches sprout from the rigid gray threads, restoring the civilization's possible futures. The Guardians' forms stabilize, their robes regaining their vibrant colors and fluid movement. "We'll help," she says, her voice steady with resolve. "Choice is what makes life worth living, and we're here to protect it."The Guardian nods, their robes now flowing with a thousand colors. "The Crossroads is through that bridge," they say, pointing to a massive bridge made of light that connects two platforms, its surface covered in branching Fate Threads that represent the most important choices in the multiverse. "But beware—the Chaos Destiny has spawned 'Fate Fixers' to guard it. They're beings of rigid, gray threads, their forms unchanging, and their touch can erase all possibilities from a Fate Thread, leaving only a single, inevitable path. One brush, and your own destiny will be fixed, with no room for choice."Echo and Li Wei thank the Guardian, then make their way across the bridge. The air grows heavier as they walk, the Destiny Dirge growing fainter, the Predestination Pulse louder, its monotonous rhythm making it hard to think of anything but the most obvious path forward. Suddenly, figures emerge from the grayness—Fate Fixers, their forms rigid and unchanging, their bodies made of stiff, gray threads that don't shift or branch, their eyes glowing with a dull, gray light."Stay open to possibilities," Li Wei says, his charge glowing brighter as he creates a barrier of purple and rainbow light around them. "Don't let them fix our fate."Echo nods, her drumbeat becoming more chaotic, more varied, as she draws on the full power of the Destiny Dirge. The rhythm sends out waves of energy that ripple through the Fate Threads, causing them to branch into new paths and making the Fate Fixers recoil, their rigid forms flickering as the possibility energy disrupts their existence. "Let's make some noise," she says.Li Wei fires blasts of energy at the Fixers, the purple and rainbow light disrupting their rigid forms and causing them to dissolve into loose threads that quickly branch into new possibilities. The Fixers retaliate, sending waves of gray energy toward them that try to rigidify the Fate Threads around them, but the barrier holds, the light of the charge and the sound of the drum combining to repel the attacks and keep the threads fluid.They fight their way across the bridge, the possibilities around them multiplying as Echo's drumbeat strengthens, the Predestination Pulse growing fainter as the Destiny Dirge is restored. Finally, they reach the Crossroads of Choice—a vast, circular platform surrounded by bridges that lead to every corner of the dimension. At the center, floating above a pedestal of light, is the Choice Core: a massive sphere of swirling, multicolored light, its surface covered in branching threads that represent all possible futures, its core glowing with a brilliant, white light that emits the Destiny Dirge—a complex, ever-changing melody that shifts and adapts as new possibilities emerge.But surrounding the Choice Core is a swirling mass of grayness—the Chaos Destiny in its purest form, a vortex of rigid determinism that pulses with the Predestination Pulse, its edges creeping toward the core, turning the branching threads into rigid, gray lines as it spreads. As it pulses, the Choice Core's light dims, and the Destiny Dirge grows weaker, making the Fate Threads around them grow stiff and unchanging."You cannot win," a voice booms from the vortex, its tone monotonous and unchanging, lacking any inflection or variation. "Choice is an illusion, a fleeting dream. The Chaos Destiny will bring order to the multiverse, fixing every fate, eliminating all uncertainty, making everything predictable and safe. It is inevitable."Echo shakes her head, her drumbeat growing stronger, more varied, as she draws on the full power of the Destiny Dirge. "Choice isn't an illusion," she says, her voice clear and unwavering. "It's what makes us alive. It's the possibility of being better, of doing better, of creating a better future. And we're here to protect it."She starts to play, weaving together a melody that combines the songs of all the Fate Threads they've encountered—the bold, branching melodies of courage, the slow, winding tunes of caution, the chaotic, ever-changing harmonies of curiosity. The Choice Core responds, its light exploding outward, pushing back the Chaos Destiny.Li Wei stands beside her, his charge pulsing with a light that blends purple and every color of the rainbow, channeling his own openness to possibilities into the Choice Core. "Every choice we've made, every possibility we've embraced—they're all part of this melody," he says, his voice filled with determination.The Destiny Dirge swells, a tidal wave of sound that drowns out the Predestination Pulse. The Choice Core's light spreads across the dimension, washing over the Chaos Destiny, which shrieks—a sound like the snapping of a million rigid threads—and begins to dissolve. The Fate Threads that had turned gray return to their vibrant colors, branching into new possibilities; the rigid paths are replaced by fluid, ever-changing melodies; and the patches of grayness are replaced by swirling, multicolored threads that shift and adapt as new choices emerge.The Fate Fixers vanish, dissolving into loose threads that quickly branch into new possibilities as the Destiny Dirge purifies the dimension. The Crossroads shakes with the force of the restored fluidity, and the entire Fate Fugue glows with a brilliant light as the Destiny Dirge fills the air, stronger and more varied than ever before.Echo and Li Wei collapse onto the pedestal, exhausted but exhilarated by the endless possibilities that surround them. The Choice Core pulses with a warm, white light, and the air is filled with the harmonious sounds of the Destiny Dirge—the bold, branching melodies of courage, the slow, winding tunes of caution, the chaotic, ever-changing harmonies of curiosity—as the dimension is fully restored.They make their way back across the bridge and the platform, which are now teeming with fluid, branching Fate Threads. The Fate Guardians are waiting for them, their forms radiant, their voices singing in a chorus of gratitude that shifts and changes with every note."Thank you," the Guardian leader says, their voice a beautiful harmony of a thousand possibilities. "You've saved not just our home, but the very concept of choice across the multiverse. The Destiny Dirge will play on, and no one will ever be trapped in a single fate again."Echo and Li Wei smile, but their attention is drawn to a faint, pulsing light in the distance—a white glow that shimmers at the edge of the dimension, a sign that another realm is in need.Li Wei stands, his charge glowing with a purple light that now shines with the essence of all possible Fate Threads, a reflection of the infinite possibilities they've preserved. "Ready to see what the next dimension has in store?" he asks.Echo nods, slinging her drum over her shoulder, its surface now etched with a pattern of branching Fate Threads that shift and change with every movement. "Always," she says. "As long as there are choices to protect, we'll be there."They step through the portal Nova opens, leaving the Fate Fugue behind, but carrying its lesson with them: that the future is not fixed, but a tapestry of possibilities, and that choice is the thread that weaves it all together. The next dimension awaits, and with it, new choices to make and new possibilities to preserve.
