In the morning(in the underground)
Morning light filtered through the cracks in the stone walls of the Underground, casting soft shadows in Sans's cozy bedroom. He stirred awake, the familiar chill wrapping around him like a comforting blanket. With a yawn, he swung his legs over the edge of the bed and slipped into his favorite blue jacket and fluffy pink slippers. He stretched, feeling the weariness of sleep melt away, and shuffled towards the door.
Next to his own door was another, adorned with a chaotic array of signs: "NO GIRLS ALLOWED!", "NO BOYS ALLOWED!", and the ever-prominent "PAPYRUS ALLOWED!" It was a daily reminder of his little brother's eccentricity. Sans smiled softly; he was used to Papyrus's flair for dramatics, even if he was already well-acquainted with the contents of that room.
As he descended the stairs, the faint sound of clattering echoed through the house. He entered the living room and was immediately greeted by the sight of his brother, Papyrus. Standing tall and proud, Papyrus was an impressive skeleton with a slightly exaggerated, geometric skull that made him look even more unique. His outfit was just as flamboyant as ever, featuring an orange-red scarf that billowed behind him like a cape, shining white armor with gold trim at the edges, and blue briefs held up by a golden belt. Red coquelicot gloves, each trimmed with yellow, and bright red boots completed his heroic ensemble.
"SANS!! WHERE HAVE YOU BEEN!?! I'VE BEEN LOOKING EVERYWHERE FOR YOU ALL OVER SNOWDIN! YOU WEREN'T AT YOUR STATION! WHERE HAVE YOU BEEN ALL DAY, SANS?!?" Papyrus exclaimed, his voice echoing with a mix of concern and exasperation. He rushed forward, his worry palpable, and enveloped Sans in a tight hug as if he feared his brother might vanish.
"Hey, hey, Pap. It's okay, I'm okay, see? I was just at the dump, that's all. You don't have to worry, Paps." Sans reassured him, gently patting his brother's back. He could feel the tension in Papyrus's frame begin to ease.
"But the dump, Sans!" Papyrus persisted, pulling back slightly to meet Sans's glowing eye sockets with his own. "What if something dangerous happened? What if you got lost in the trash?!"
Sans chuckled softly, his usual laid-back demeanor shining through. "I promise, I'm fine. But I did find something pretty interesting while I was there." He reached behind his back and pulled out Fenton Works box out of nowhere, the relic of his recent adventure.
Papyrus's eyes lit up with curiosity, his previous worry momentarily forgotten. "What is it? What did you find? Is it a new weapon? A new treasure? Or is it a new action figure?" His voice rose dramatically at the last suggestion, clearly excited by the thought.
Sans grinned, enjoying the enthusiasm radiating from his brother. "Actually, it a ghost portal blueprint paps. I think we might be able to build it together. Though not the ghost part because we are making a portal to bring him back."
Papyrus gasped, nearly bouncing on his heels."Really that's amazing brother ".Papyrus grab his brothers arm as his eyes are field with determination in them." Then what are we waiting for?! Let's get started right away!" His excitement was infectious, and Sans couldn't help but feel a rush of energy at the prospect of working on this project together.
With a shared look of determination, the two brothers headed towards Sans's lab, ready to dive into the unknown. The adventure of building a portal awaited them, and the thrill of discovery hung in the air like static electricity.
The clatter of tools echoed in the basement, a symphony of bone against metal. Sans and Papyrus, two skeleton brothers bound by grief and determination, toiled away at their ambitious project: a portal to rescue their father, the old royal scientist, from the CORE—the very creation that had imprisoned him. Sans's old lab, now a chaotic workshop, was filled with the strange detritus of their endeavor: salvaged parts, glowing crystals, and blueprints covered in frantic scribbles. They worked in secrecy, their clandestine operation hidden from the unsuspecting monsters of the Underground.
The materials, scavenged from the Waterfall dump, were brought in by Sans, his ability to shortcut—to teleport—making him the ideal supplier. Papyrus, with his unique ability to fly, assisted where he could, though his time was often consumed by lessons with Undying, a member of the Royal Guard and a close friend. Sans often found himself working alone, the rhythmic clang of his tools a lonely counterpoint to the silence of the basement.
The task, while demanding, wasn't insurmountable. Unlike humans, who relied on physical strength, monsters drew power from their very essence—magic. This inherent magical ability allowed the brothers to complete the portal's construction in a mere two weeks. Sans, fueled by an unwavering resolve, sacrificed sleep during this period, a secret he kept from his ever-optimistic brother.
With the portal frame complete, a new challenge emerged: the generator. Papyrus, ever the pragmatist, posed the crucial question: how to power the portal without the CORE's energy?
"Well," Sans replied, his voice a low hum, "Dad did leave us a void sample while he was working on destroying the barrier without a human soul. All we need is the ectoplasm component."
He unfolded a blueprint, revealing not the portal itself, but the intricacies of the generator. "According to Fenton's notes," Sans explained, pointing to a section of the diagram, "ectoplasm is self-sustaining. It creates its own power source without needing refills. The problem is, the blueprint doesn't explain how to create it."
Papyrus, his eye sockets wide with sudden understanding, examined the blueprint, then the box of collected materials, his gaze flitting back and forth. He spotted a vial containing a glowing green liquid. He picked it up, his bony fingers carefully holding the fragile container, and presented it to Sans.
"I THINK THAT'S THE ECTOPLASM FENTON MENTIONED, BROTHER! MAYBE THIS WILL BE OUR POWER SOURCE! NHEHEHEHEHE!" Papyrus's signature laugh boomed through the basement, a sound of hope and anticipation. Their journey was far from over, but with the ectoplasm secured, the brothers stood on the precipice of success, ready to face whatever challenges lay ahead in their quest to bring their father home. The hum of the almost-complete generator added a hopeful counterpoint to the clatter of their tools.
Unaware of the impending doom, the brothers excitedly prepare to activate the portal. However, the moment it powers up, disaster strikes. Adding to the chaos, an unexpected guest materializes at the Ruins' exit, their arrival heralding further trouble for the Underground.
