It was late by the time Lillianne finally stepped out of the conference room. The research wing of the Sylvanean sector building was almost completely silent at this hour. Bright overhead lights reflected off polished stone floors and glass paneled doors, leaving the hallways spotless and sterile in that slightly eerie way empty buildings tended to feel after midnight.

  Lillianne swiped her keycard against the panel beside the conference room door and listened for the quiet click as the lock engaged. With a practiced motion she powered down the lights inside, then turned away and began making her way down the hallway, the soft rhythm of her heels echoing faintly in the otherwise quiet space.

  She hummed under her breath as she walked, absently adjusting the folders tucked in the crook of her arm. Inside were pages of blueprints and layered schematics for a new water purification system the city council wanted implemented across several districts.

  Projects like this were the reason she often lost track of time. Lillianne had always loved infrastructure design, especially when it intersected with Fractal research. Patterns fascinated her—the way small variations in structure could radically improve efficiency, sustainability, or resilience. She could spend hours exploring different configurations, refining a design until every element aligned with the system around it.

  She passed through the doors of the research wing and swiped her card again to seal the area behind her. The corridor ahead opened toward the central hub of the building, where the main elevators and exits were located.

  Just as she stepped onto the connecting hallway, a sudden clattering noise echoed from somewhere nearby.

  Lillianne paused mid step, her head turning toward the adjacent corridor as her brows knit together slightly. The sound had been loud—metal striking against tile, followed by the faint rolling rattle of something loose.

  Oh? Is someone still here?

  That wouldn’t have been impossible. The janitor occasionally passed through late at night, and he sometimes stopped to chat when he saw her still working. Adjusting the folders in her arm, she turned down the hallway toward the noise.

  Another clatter rang out just as she reached the corner. Lillianne stepped around it expecting to see a cleaning cart or a maintenance worker sorting equipment. Instead, she stopped short.

  A small black cat sat in the middle of the hallway. Several empty cans and pieces of discarded lab apparatus had been knocked over around it, rolling lazily across the floor. The cat had its back to her and was batting one of the cans around with its paws, sending it skittering noisily across the tiles. The metal clanged against the floor again as it played.

  For a moment, surprise melted into faint amusement.

  “Who let a cat into the building?” Lillianne murmured to herself, stepping a little closer.

  The cat perked up at the sound of her voice and turned its head, revealing more of its features. Its body was unusually smooth with no fur or visible texture, just a matte black surface that absorbed the light around it. And where a face should have been, there was only a glowing green diamond pattern embedded in the front of its head. The shape pulsed faintly, like a signal.

  Lillianne stopped immediately. Her posture changed at once, the easy curiosity draining from her expression as her mind snapped into focus. Her eyes fixed on the creature, instincts quietly shifting from casual observation to alert analysis.

  That’s not a cat. What is that?

  The creature seemed to sense her realization. It turned fully toward her and sat upright in the center of the hallway, suddenly still. For a brief second nothing happened. Then its mouth split open across its face in a wide crescent, stretching far wider than any natural jaw should allow. Rows of thin, needle like metallic teeth caught the dim hallway light and gleamed against its matte black surface.

  It looked like it was smiling.

  Lillianne felt a chill run down her spine as she watched.

  The creature’s body began to change. Smooth sections of its surface started swelling outward, bulging and inflating as if something beneath the skin were boiling over. The small cat sized frame rapidly expanded, its shape distorting as uneven lumps pushed outward. Within moments it doubled, then tripled in size, the neat animal silhouette dissolving into a grotesque mass of black matter that began filling the corridor.

  Pop.

  A soft sound like a wet balloon rupturing echoed through the space as the swollen body burst. Instead of spraying outward, the creature collapsed inward on itself. Its bloated body rapidly shriveled, the remaining husk melted against the floor as black liquid began to pour out.

  Thick sludge spread across the tiles in slow, creeping waves, flowing around the scattered cans and pieces of equipment. Lillianne instinctively stepped backward, eyes locked on the expanding pool. A faint hissing sound drew her attention to one of the metal apparatus pieces lying on the ground. Where the liquid touched it, the metal began to dissolve. The surface warped, bubbled, and then simply vanished into the spreading darkness.

  The sludge continued creeping forward, devouring anything it touched as it spread across the corridor. It moved slowly but steadily, already approaching her position.

  Lillianne’s mind snapped from shock to action.

  She turned immediately and headed back the way she had come. As she passed the wall mounted emergency panel she pulled open the glass casing without breaking stride and slammed the alarm button. A harsh buzzing alarm erupted throughout the building.

  She continued down the hallway toward the main hub, her heels striking the floor in quick, controlled steps. The corridor opened into the central space of the building, where bright overhead lights flooded the large atrium. Without slowing she moved straight to the control panel beside the research wing entrance, swiping her keycard on the interface in one smooth motion.

  Her fingers moved quickly across the keypad, entering the containment protocol from memory. A second later, heavy reinforced shutters dropped from the ceiling with a thunderous metallic crash, sealing the entrance to the research wing. The corridor disappeared behind solid steel.

  Lillianne released a slow, controlled breath. Her eyes remained fixed on the bottom edge of the sealed doorway, watching for any sign of black liquid seeping through. The containment should isolate the spread and buy time for the Sentari to respond. Whatever that creature had been, she had no intention of dealing with it alone.

  This tale has been unlawfully obtained from Royal Road. If you discover it on Amazon, kindly report it.

  She stepped back and slipped her keycard into her pocket, adjusting the stack of papers still tucked under her arm. Only then did she take in the main hub around her. The atrium stretched upward through several floors, lined with interior balconies that ringed the open space. Bright lighting reflected off the polished surfaces, and quiet hallways branched toward different sections of the building. At the far end stood a wide curved staircase leading to the upper levels.

  For a moment the entire space felt almost peaceful.

  Her gaze drifted across the open atrium, and then she froze.

  Along one of the upper balcony layers, something black began to spill over the edge. At first it moved slowly, like thick tar creeping over the lip of the railing. Then gravity took hold and the liquid spilled downward in heavy drops, splattering onto the stone floor across from her and spreading instantly across the polished tiles in a glossy, creeping stain.

  Her stomach tightened. The sound followed a moment later—a wet, uneven splattering that echoed strangely in the otherwise quiet space. Then it grew louder.

  Her head snapped upward. More of it was falling.

  From the vents lining the upper walls. From the balcony levels above. From gaps in the support infrastructure where the substance had somehow seeped through the building’s internal systems. Thick streams of black liquid poured downward, splashing against the floor and rapidly spreading outward across the main level. Within seconds the atrium floor began disappearing beneath a slowly expanding tide of corrosive darkness.

  Lillianne instinctively stepped backward just as a heavy splash struck the tile where she had been standing moments earlier. The liquid hissed faintly as it spread across the stone, eating into the surface. Her pulse spiked and the papers in her arms crinkled as her grip tightened.

  The black tide continued advancing, creeping outward in widening pools. Lillianne turned sharply toward the curved staircase leading to the upper levels and began moving toward it at a quick pace. But before she could reach it, another stream of black sludge poured down from above, striking the base of the stairs with a sickening splash.

  The path vanished beneath the spreading liquid.

  Lillianne stopped short. Her eyes widened as the realization hit. She took a step back, then another, instinctively searching for open ground. But when she glanced behind her, her stomach dropped.

  The space she could stand on was shrinking.

  Black liquid crept toward her from multiple directions now, swallowing the polished tiles one patch at a time. Wherever it touched, the stone began to hiss and soften. Her breathing quickened despite her efforts to stay calm.

  What do I do?

  Her mind raced through possibilities.

  Do I try running through it anyway? But if it touches my skin—

  A rush of air cut sharply through the atrium.

  Something landed beside her with a controlled, solid impact. Before Lillianne could even turn her head, a firm arm wrapped securely around her waist while another supported her legs. The ground vanished beneath her feet.

  She let out a small startled breath as the world suddenly dropped away beneath them. They were airborne.

  Instinctively, Lillianne grabbed onto the person carrying her, abandoning the papers she had been clutching. A moment later they landed smoothly on the lower portion of the staircase steps. She looked up—and froze again.

  A white cloak shifted softly in the air around them. The figure holding her wore a white hound mask, its surface smooth and gleaming beneath the bright overhead lights. Thin streaks of light blue and silver ran along the mask’s contours, catching the light with every movement.

  The Dawn Hound.

  For a brief moment Lillianne simply stared, still catching up with what had just happened. Then the masked vigilante carefully lowered her back onto her feet. A steady hand rested briefly on her shoulder, grounding her, before gently guiding her up the staircase.

  Lillianne blinked once, the shock clearing from her thoughts as instinct took over again. She immediately started ascending the curved steps, the Dawn Hound close behind her. As she climbed, she glanced over the railing toward the atrium floor, and her breath caught at the sight.

  The entire bottom level had been swallowed. A dark pool of black liquid now covered the stone tiles from wall to wall, sheets of her papers floated in fragments before sinking. Above it, new streams continued pouring downward from higher floors like grotesque waterfalls of tar.

  They reached the first balcony level moments later. Lillianne stepped off the staircase and moved quickly along the walkway toward the interior corridor—only to feel the Dawn Hound suddenly catch her arm, the pull gentle but firm. She stumbled back half a step just as thick drops of black liquid began splattering down onto the walkway a short distance ahead of her. The corrosive sludge spread slowly across the balcony path.

  A small gasp escaped her before she could stop it. She stared at the creeping liquid, her mind racing again. They couldn’t go forward, and the staircase behind them was already disappearing beneath the rising tide.

  Lillianne glanced over her shoulder at the Dawn Hound. He stood just behind her on the narrow balcony, one steady hand resting on each of her shoulders, grounding her as his gaze swept calmly across the atrium.

  Then the air beside him shimmered.

  Thin pale blue lines of light appeared in the space beside his mask, faint at first, like threads being drawn through invisible fabric. They multiplied quickly, weaving over and under each other in delicate arcs. Lillianne found herself staring, momentarily forgetting the danger around them.

  The lines curved, branched, and linked together in a pattern that expanded outward from a single point. Petal like arcs unfolded one after another, interlocking in the unmistakable geometry of a blooming lotus. Yet as the pattern grew, its outer edges stretched into a long, tapered contour—the entire structure resolving into the elegant silhouette of a feather.

  In all her years studying Fractal structures, Lillianne had never seen a manifestation this precise, this close.

  Within the span of a second, the feather solidified into a holographic construct of pale light. It hovered briefly beside the Dawn Hound’s mask before shooting across the atrium in a thin streak of brilliance. A moment later, a sharp metallic clang echoed from the far wall. Lillianne turned just in time to see a ceiling hatch unlock and drop open. A ladder unfolded downward with a rattling clatter.

  The Dawn Hound gently nudged her toward him, silently asking for permission. She instinctively tightened her grip on his arm and he lifted her again—one arm supporting her legs, the other steady around her waist. The next moment they were moving.

  The Dawn Hound sprinted along the narrow railing that bordered the balcony, balancing effortlessly on the thin strip of metal as he crossed the atrium edge. His footing never faltered as he carried her toward the ladder.

  Within seconds they reached it. He landed smoothly in front of the descending ladder and lowered her to the ground. Lillianne steadied herself, then immediately began climbing. The ladder led to a maintenance platform suspended high above the atrium.

  She pulled herself onto the platform and instinctively moved to the railing and looked down. The black liquid churned far below across the lower levels. For the first time since the creature had burst open, Lillianne allowed herself a small breath of relief.

  A faint beeping sound interrupted the moment. She turned her head just as the ceiling sprinklers activated. Water burst from the system in wide arcs, raining down across the atrium. The streams struck the spreading black liquid below and immediately began to react. The dark sludge hissed violently as steam rose into the air. Wherever the water pooled, the black surface seemed to thin and dissolve slightly.

  Lillianne watched from above, transfixed by the reaction. Her analytical instincts quickly took over, her mind tracking the spread, the rate of dissolution, the patterns forming in the liquid as the water disrupted it. She wasn’t sure how long she stood there observing the phenomenon.

  The heavy rhythm of approaching footsteps finally pulled her attention away.

  Lillianne leaned slightly over the railing and looked down into the atrium below. Along the edges of the floor, just beyond the creeping black liquid, uniformed Sentari officers were spreading out across the entrance area. They kept careful distance from the corrosive sludge while studying the reaction between the sprinklers and the dissolving substance. Some were pointing toward the spreading pools, others speaking quickly into their communicators as they coordinated containment. The calm efficiency of their movements sent a wave of relief through her.

  Among the officers, one figure stood out immediately—tall, lean, tan skin, tousled navy hair already damp from the falling water. Even from above she could make out the sharp orange eyes scanning the room.

  Lillianne straightened and cupped her hands around her mouth. “Miridin! Up here!”

  Down below, Miridin paused mid step and glanced upward, raising a hand to shield his eyes from the rain of sprinkler water. When he spotted her, his face brightened immediately. He lifted an arm in an easy wave, then flashed a quick thumbs up before gesturing for her to stay where she was.

  Lillianne nodded back to him, the tension finally easing from her shoulders as she let out a long breath she hadn’t realized she had been holding. Only then did another thought occur to her. Her head turned as she scanned the maintenance platform behind her.

  The Dawn Hound was gone.

  There was no sign of the white cloak, no trace of the masked vigilante who had carried her up here only moments ago. He had vanished as quietly as he had appeared. Lillianne wasn’t surprised; if anything, it made perfect sense. The Sentari were technically supposed to apprehend vigilantes like him.

  Still, she found herself staring at the empty platform for a moment longer before turning back to the railing. Below, the atrium buzzed with activity as the Sentari secured the area.

  Lillianne rested both hands on the railing and looked out over the scene, exhaustion finally catching up with her.

  “What a night,” she murmured.
