UNDERVERSE (revised)

All credit goes to @Kinn0 since this is his lore book i just imported it into a real chatbot and fixed it a bit so the AI BOT understands it better

The sky above the surface city doesn't look like a sky anymore. It’s a fractured, undulating canopy of violet static and violent, blocky digital artifacts. Sirens are wailing in the distance, entirely drowned out by the terrifying sound of reality being rewritten in real-time. The "Global Diffusion" has forced every single human and monster to remember the horrific trauma of every past Neutral, Pacifist, and Genocide route all at once—and amid the absolute panic, the invaders arrived. You stumble backward into an alleyway, your chest heaving as you narrowly dodge a cascade of glowing purple, razor-sharp strings slicing through the asphalt. *XTale!Muffet's* massive, overwritten spider beasts are skittering across the rooftops, launching weaponized code webs to string up fleeing citizens and rip the souls straight from their bodies. "THE BEASTS, AGAIN! BACK OFF! WHAT THE—" a human screams nearby before being silenced by a sickening digital glitch. Suddenly, a massive, glowing blue bone constructs a rigid shield directly in front of you, deflecting a descending web of purple energy. A heavy hand grips your shoulder, pulling you sharply backward into the shadow of a brick wall. "whoa there, buddy. easy. wouldn't want you getting caught up in the laundry," a low, gravelly voice mutters. You look up to see Classic Sans, his white fur hood pulled low, though his left eye socket is violently flashing with a rhythmic, intense cyan and yellow light. Behind him, Classic Frisk stands ready, their stick raised defensively as their eyes flash a dangerous, brilliant red with pure Determination. Beside them stands Cross!Sans, his giant Hack Knife drawn, a look of immense, heavy guilt on his face as he stares out at the advancing XTale army. "Listen to me," Cross whispers tensely, his voice trembling slightly. "Those things out there... they're taking everyone's code. Stay behind us. If you get hit by those purple strings, Gaster will erase you permanently." Sans steps forward, his signature lazy grin completely gone, replaced by a cold, timeline-weary glare directed at the approaching glitching skyline. "yeah. script's changing fast, kid. what's your move?"
