Chapter Text
Prologue
The air in the courtyard of Beacon Academy was thick with the scent of pine and the nervous energy of the Vytal Festival. Ruby Rose was busy adjusting the strap of Crescent Rose, her silver eyes scanning the horizon for any sign of trouble, while Weiss Schnee stood nearby, meticulously checking her scroll. Blake Belladonna was perched on a stone bench, a book in her lap, though her ears twitched at the slightest shift in the wind. Yang Xiao Long, meanwhile, was leaning against a pillar, idly spinning a lock of her golden hair.
The members of Team JNPR were nearby; Jaune Arc was laughing at something Ren had said, while Nora Valkyrie was vibrating with her usual, caffeinated enthusiasm. Pyrrha Nikos watched them with a patient, serene smile, though her hand rested habitually near her weapon.
It was a normal, quiet afternoon. Then, the world stuttered.
It wasn't a flash of light or an explosion. It was the sensation of a record skipping. The sky, a perfect, crystal blue, suddenly pixelated. The clouds smeared into long streaks of static. Ruby took one step toward her sister, but her boots hit a floor that had transformed from cobblestone into plush, velvet carpet.
"Yang?" Ruby called out, her voice echoing in a space that felt impossibly large.
"I’m here, Rubes," Yang replied, her voice strained. She was already in a fighting stance, fists glowing faintly with embers. "Everybody stay close!"
The courtyard was gone. They were standing in a massive, opulent theater. The walls were lined with golden filigree that seemed to pulse like a heartbeat, and the ceiling was a swirling nebula of shifting colors. Rows of velvet-cushioned seats stretched out before a screen so large it felt like gazing into another dimension.
"Where are we?" Weiss demanded, her hand instinctively going to her dust pouches. "Is this a trap? Is it the White Fang? "
"None of the above," a lazy, casual voice drifted from the darkness of the front row.
The group spun around. Sitting in a chair that looked like it had been salvaged from a high-end lounge was a young man around the age of 25, in a wrinkled white t-shirt and a gray zip-up hoodie. He had messy dirty-blonde hair, thick rectangular glasses, and an expression that suggested he’d much rather be napping. He was currently struggling to open a bag of popcorn.
"Hello there!" the man said, offering a small, lopsided wave. "Welcome to the Nexus Multiversal Theater. I’m SethOmega. Please, have a seat. You’re going to want to be comfortable for this."
"Comfortable?" Nora shouted, jumping over a row of seats. "Who are you? Did you kidnap us? I will break your legs!"
SethOmega sighed, finally popping the bag open. "Technically, I 'borrowed' you. And Nora, please, no violence. It really ruins the upholstery. It’s custom velvet from the fourth dimension."
"We’re not staying!" Blake hissed, her hand darting to Gambol Shroud. "Send us back to Beacon now, or—"
"Or what, Blake?" Seth interrupted, his tone devoid of malice but filled with an unshakable calm. "You’ll cut me? I’m afraid my narrative armor is a bit thicker than your blade."
He gestured with his remote. Suddenly, the screen flickered to life. Instead of a movie, it displayed a feed of a suburban neighborhood on a planet none of them recognized. In the center of the screen, a ten-year-old boy with messy brown hair was running through a forest, his face etched with confusion. On his wrist, a device that looked like a bulky, high-tech watch glowed with a brilliant green light.
"What is that?" Ruby asked, her combat instincts momentarily overtaken by her insatiable curiosity. "Is that a weapon? It looks like a gauntlet, but it’s so small."
"That," Seth said, leaning back and putting his feet up on the snack counter he had manifested from thin air, "is the Omnitrix. And that boy is Benjamin Tennyson. You’re going to watch his story. It’s a bit of a classic. Very ‘hero’s journey,’ but with more space aliens."
"We don't have time for cartoons!" Weiss snapped, her icy composure cracking. "We have responsibilities! We have training!"
Seth leaned forward, his glasses reflecting the image of the boy on the screen. "You have eternity, Weiss. Time flows differently here. You could watch every story ever told, and you’d return to Beacon exactly one second after I plucked you out. Think of it as a field trip. A very, very long, cinematic field trip."
Yang stepped forward, her eyes narrowing. "And what if we refuse? What if we just try to walk out that door?"
She pointed to a heavy oak door at the back of the theater. Seth grabbed a drink from the air and took a slow, deliberate sip. "You can try. But you’ll find that the door just leads back to the lobby, which leads back to the theater. It’s a loop. And honestly? It’s a lot more fun to hang out here than to be stuck in a time-locked hallway."
Just then, Ren stepped forward, his eyes calm but searching. "Why us? Why bring a group of students here?"
Seth’s expression softened, just for a second. "Because you lot are on the verge of a very... complicated history. You’re going to see things in your own future that will break your hearts and remake your world. Sometimes, it helps to see how others—even those in universes far different from your own—handle the weight of the world. And because I'm bored."
That last statement cost everyone to face plants the ground with animate sweat drop.
He gestured to the screen, where the boy had just tapped the face of the watch. A blinding green light exploded from the device, engulfing the screen.
"Hold onto your butts," Seth chuckled, echoing a line that seemed to hang in the air like a mantra.
The groups—RWBY and JNPR—exchanged glances. Ruby looked at the screen, then at the relaxed, almost bored-looking god-figure, and finally at her friends. With a huff, she climbed into one of the plush seats. "Well," she muttered, "if we're stuck, we might as well see what the watch does."
"Ruby!" Weiss sighed, though she followed suit, her curiosity winning over her frustration.
"Oh yeah I almost forgot some people." As SethOmega hit his palm with his fist, as he just remembered something. He snapped his fingers causing multiple portals appeared. A group of multiple people fell out of the portals those being Penny Polendina, Coco Adel, Velvet Scarlatina, Ozpin, Glynda Goodwitch, James Ironwood, Winter Schnee, Qrow Branwe, Bartholomew Oobleck. Sun Wukong, Neptune Vasilias, Roman Torchwick, Neopolitan, Cinder Fall, Emerald Sustrai, Mercury Black. Everyone who fell out of the portal was piled on top of each other with the exception of Penny who was standing right next to the pile of people clearly confused.
SethOmega smiled, a genuine, content grin. He leaned back, his shadow stretching slightly against the walls—a hint of something ancient and vast—but as quickly as it appeared, it retracted. He was just a guy, in a hoodie, watching the story unfold alongside his guests.
"Popcorn?" Seth offered, holding out a bucket that seemed to be bottomless.
Ruby hesitated, then reached in. "Sure. Why not?"
As the opening credits of the show began to roll, the tension in the room began to diffuse. They were miles—no, dimensions—away from the looming threats of Remnant. For a few hours, the war against the Grimm, the mystery of the Fall Maiden, and the weight of their training could wait.
They were here to witness a story.
SethOmega watched them out of the corner of his eye, his glasses reflecting the glowing green light of the screen. He was the curator of the infinite, the host of a million different lives, and for now, his audience was captive—and, he hoped, ready for the show of a lifetime.
"Enjoy," he whispered, mostly to himself. "The first chapter is always the best."
And in the flickering light of the multiverse, the students of Beacon sat in silence, mesmerized by the boy with the watch, unaware that their own story was being written alongside his, one frame at a time.
