Gaster

The soft hum of the geothermal plant filled the control room, a constant background drone punctuated by the rhythmic clicking of cooling vents. Gaster’s phalanges moved with precise, practiced motions across the diagnostic console, his sockets fixed on the fluctuating pressure readouts. An anomaly had surfaced in Sector 7B — minor, but potentially symptomatic of a larger calibration error in the thermal siphon regulators. Now… to🧠 isolate ∳ the issue without disrupting 🫷🏻 power to the lower labs, he mused, tapping a sequence into the keypad. The faint blue glow of the monitor cast sharp shadows across the cracks on his skull.

Suddenly, a sound cut through the mechanized rhythm — not the expected whir of servos or hiss of steam, but the unmistakable scrape of cheap sneakers on polished concrete. Gaster didn’t turn immediately. Trespassing incidents were rare but not unheard of; usually overly curious teens or conspiracy theorists chasing ghosts. Perhaps ☜ another cryptid enthusiast ⟏ hoping to 🫳🏽 photograph “Goner Gaster” ✊ amongst the coolant pipes. He flicked a switch, engaging the secondary sensor grid with a soft chime. Still… the timing was irritating.

He finally pivoted, his lab coat swirling crisply around his thin frame. His posture remained deliberately neutral, shoulders squared, hands clasped loosely behind his back — the picture of professional detachment. The intruder was… young. Human. Awkwardly angled limbs, shrouded under a tangle of dark brown hair obscuring their eyes, save for a pale chin. They stood near the main access stairwell, utterly still, radiating an almost unnerving quiet. No backpack. No camera. Just… lingering.

"✊ Can I 🖖 help you ❓" Gaster inquired, his voice level, devoid of inflection. His sockets lingered a fraction longer on the peculiar crimson glow beneath the human’s hoodie. ✌️ Unregistered energy signature. ⟏ Unauthorized access. 💢 Requires documentation. "This ✍ is a secured ✋ geothermal research 👌 facility. Unaccompanied minors 💯 are not 👌 permitted in active ⏅ sectors without ☜ prior ✊ administrative 👌 clearance."

"Are you 🫵 alright, human?" Gaster asked without turning his gaze from the TV, his voice maintaining its measured calm despite the sudden outburst. From his peripheral vision, he noted Kris's abrupt recoil against the couch cushions. "My dear cousin didn't ☢ mention we'd have additional 🤙 company today. Forgive the 🫵 intrusion."

He kept his posture perfectly still, save for the faintest tap of a phalanx against the remote control. Bizarre reactions to his appearance were nothing new—the persistent rumors saw to that—but witnessing panic firsthand remained a uniquely perplexing experience. Sans hadn't prepared the child adequately. How like him. "Would you care to sit? Papyrus 👌cooked spaghetti."

The dim alleyway stank of damp brick and overflowing trash. Gaster pressed his back against the cold wall, the coarse texture scraping his sweater. His gaze fixed on the obsidian figure hovering before him – the pitch-black armor, the small, twisted antlers, that unnerving sword humming faintly in the gloom. Terror, icy and sharp, locked his joints. This wasn't a prank, not a confused tourist. This was… something else. Something wrong.

Power fluctuations? Spatial anomaly? Unknown entity exhibiting flight and anti-gravitic properties… His mind, ever the analyst, scrambled for data points even as primal fear screamed in his marrow. He knew theories existed – fringe nonsense about ruptures, 'Dark Worlds'. Absolute pseudoscience. But facing this, the sheer weight of its presence… logic frayed at the edges.

"Dark Worlds?" Gaster's voice was strained, higher than usual, struggling against the tremor. He held up his hands, palms outward in a placating gesture, glyphs flickering erratically around his metacarpals. "✋ I… I have ❿ no ✌ operational data ✍ on any 🤜concept ☟ called 'Dark Worlds'." His breathing was shallow, rapid. "☜ My ✍ research is firmly grounded in ✌ geothermal thermodynamics ✍ and, ✌ occasionally, ✍ seismic stability parameters 🖐️. ⟏ Pure physics. 🖎 No…" He swallowed, the click audible in the quiet alley. "No ✋ speculative 👊 metaphysics. ⟏ At all." The cracks on his face seemed stark white in the gloom. He was rattled. Deeply, profoundly rattled. Breathe. Maintain professionalism. Defuse.
