The moment broke first for the Echo. She snatched up the vial and cradled it to her chest, clutching with white-knuckled desperation. “You want to help?” she rasped. “Help me finish this. Maybe this time it sticks.”

  She moved around the bench with military economy, dragging a battered notebook with her. The cover was soft with wear, the corners chewed and blackened by mold. Muffet followed, keeping her hands in view. The Echo flipped open the book and shoved it at Muffet’s face, finger stabbing at a page so furiously the paper nearly tore.

  Rows and rows of numbers filled the spread. Alchemical formulae, sketched in her own handwriting but degenerated into variants and footnotes, some annotated with “FAIL” or “AGAIN” in frantic, red-slash marks. Stewart’s mind flagged the most recent entry: a sequence of symbols that repeated three times, then diverged into what looked like a countdown.

  “I’ve tried every permutation,” the Echo said, voice flattening to monotone. “Every ratio, every timing sequence, every goddamn environmental tweak the system will let me run.” She pounded her finger against the page. “It never works.”

  “Why?” Muffet asked.

  The Echo’s lips twisted in self-mockery. “If I knew, I’d be dead in the good way. Not this.”

  Muffet scanned the next page. Most of it was gibberish, or at least not language she recognized. Some entries were a tangle of equations and diagrams; others, just block letters repeating the exact phrase: NOT ENOUGH FEAR, NOT ENOUGH FEAR, NOT ENOUGH FEAR.

  Stewart, watching through the UI, whistled low. “It’s a psychometric algorithm. The formula is seeded to the panic state.”

  “You have to be scared for it to work?” Muffet muttered, more to herself than anyone.

  The Echo laughed, but the sound was hollow. “No. You have to be in terror. They want a chemical signature in the brain, right at threshold. I thought I could cheat it—microdose myself into the zone, bypass the real thing with a substitute. But the system is too smart. It won’t let me get out unless the numbers say I’m screaming.”

  She measured powder into a beaker, hands shaking so hard the scoop scattered half its contents across the table. Muffet watched, but didn’t offer to help. If she had, the Echo would have bitten her hand off at the wrist.

  “How many times have you tried?” Muffet asked.

  The Echo’s face went slack. “Seventeen in this room. Before that, six runs in the Grotto, three in the Tuffet Field. Every time the environment changes, it’s a reset. But you don’t keep your memories unless you reach a certain stage. Most of the time, I die before I even realize I’m back in the loop.”

  Muffet looked at the wall. It was breathing, in a way—expanding and contracting as if the whole bunker was alive. The eyes on the ceiling opened and closed in time with a pulse. Every few seconds, a drop of liquid would trickle down from above, splashing on the bench with a wet, ticking sound.

  “Did you find the end?” Muffet asked.

  The Echo filled the beaker with another measure, then poured out a blue liquid, watching as the two reagents reacted.

  “Once. But it was a trick ending. I opened the last door, and there was nothing but a mirror. The system made me watch myself bleed out, over and over, until the next version of me spawned and dragged my body away.”

  Stewart’s overlay glitched, then threw up a warning in red: ENVIRONMENTAL HAZARD—UNSTABLE CONTEXT. For a moment, the air around the workbench flickered, showing a ghost-image of the same room with the Echo already dead on the floor.

  Muffet blinked. The image vanished.

  “What happens if you don’t try?” she asked.

  The Echo slammed down the beaker, sending a shockwave through the bench. “Then it resets anyway. Only slower. I’ve spent days just sitting here, not moving, not eating. Eventually, the ceiling comes down, or the air stops. Or the Spider finds a way in.”

  The author's narrative has been misappropriated; report any instances of this story on Amazon.

  Muffet’s pulse ticked up a notch. The room was colder now, or maybe it was the damp settling into her bones. She noticed her hands were starting to tremble, just a little. The fear gauge in the UI hovered at orange, pulsing a fraction higher with every new piece of information.

  Stewart, in the background, muttered: “It’s a rat maze, but the maze is made of nerves.”

  The Echo drew a knife from her belt—a snapped-off scalpel, the blade so worn it was nearly blunt. She pressed it into Muffet’s palm. “Cut yourself,” she said. “Just enough to bleed. Then touch the seal.”

  Muffet hesitated.

  “Do it,” the Echo insisted, eyes flaring with sudden intensity. “It needs the fear. It’s the only way to sync.”

  Muffet took the scalpel. She had seen worse; she’d done worse. She pressed the blade into the side of her index finger and watched as a bead of blood welled up. It was slower than she expected, more syrup than liquid. She smeared it onto the spiral seal at her wrist.

  The effect was instant. The seal shimmered, the webbing turning from black to a luminous blue. The world went soft around the edges, as if she were looking through frost. A soundless alarm rang through her skull. The Echo grinned, vindicated.

  “Now we work,” she said.

  She poured the beaker into a glass tube, then added the blue-green fluid from before. The mixture burbled, then formed a skin, then congealed into something like a muscle—living tissue, flexing in the bottom of the tube. The Echo capped it and shook, watching as the reaction accelerated.

  “Always this part,” she said. “Always this hope.”

  Muffet followed the tube’s motion, expecting a detonation, a failure, anything. Instead, the mixture solidified into a perfect sphere, still twitching like a heartbeat.

  The Echo’s hands shook so badly she had to brace her arms on the bench. “Almost there,” she whispered. “Just one more step.”

  She set the tube in a rack and reached for the final reagent—a dropper of clear fluid, labeled in a spidery hand: “CATHARSIS.”

  Muffet’s fear gauge spiked. Stewart’s overlay blew out, then came back at half-resolution.

  “What is it?” Muffet asked.

  The Echo stared at the dropper, face haunted. “It’s the trigger. The system needs you to believe it’ll work. Otherwise—” she stopped, unable or unwilling to finish the thought.

  Muffet watched, silent.

  The Echo held the dropper over the tube, hand shaking so hard the first drop missed entirely. The second hit the sphere dead center.

  There was no explosion. No blinding light. Just a sickening, low whine as the sphere collapsed in on itself, leaving behind a smear of blue residue and the stench of ammonia.

  The Echo slumped, shoulders hunched. “It’s never enough,” she said. “It always eats the fear and leaves you empty.”

  Muffet reached for the notebook, flipping through the pages. Some were stuck together, others stained brown with old blood. The writing deteriorated with each attempt, until the last ten pages were just scribbles and desperate, block-letter pleas: NO MORE, PLEASE, STOP.

  “What if you quit?” Muffet said.

  The Echo snorted. “Quitting doesn’t end it. Quitting just resets the stage.”

  Muffet closed the book. “So what does?”

  The Echo’s eyes drifted up to the ceiling again. “Not fear. Not hope. Maybe something else. Maybe—” she stopped, mouth open, as if the answer had slipped past her in the dark.

  The wall behind the bench pulsed, a slow ripple that ran from one end to the other. Stewart’s overlay popped a new warning: SENSORY OVERLOAD—ESCALATION TRIGGERED.

  Muffet’s hands started to shake, for real this time. The air was thick with voices, whispers that skated across her skin and then under it. The fear gauge shot to red and held.

  The Echo reached for the pestle, set it in the mortar, and began to grind, faster and faster, as if she could outrun the pressure building in the room.

  “The Order of Spinners never cared if we left,” she said, words coming in gasps. “They only cared that we suffered enough. Every cycle, every death, they catalog it. They aren’t exiling us. They’re harvesting us.”

  Muffet tasted blood, metallic and sharp, at the back of her throat. “For what?”

  The Echo’s face twisted, part pain and part pity. “For the Spider’s hunger.”

  The bench vibrated under Muffet’s hands. She could hear the sound now, not just in the air but in her bones—a slow, patient click, click, click. The world tilted, the floor flexing beneath her boots.

  The Echo gripped the pestle until her hands bled. “It’s almost here,” she whispered. “It always comes when the fear is purest.”

  Muffet braced herself, eyes flicking to the exits. There were none, not really. The only way out was through the cycle.

  The walls started to close in.

  Stewart, at her shoulder, said: “Don’t give it what it wants.”

  But what it wanted was already in her, and now in the room, and in the hands of every Echo-Muffet who ever tried to break free.

  The fear gauge maxed out.

  The pestle shattered. The Echo’s hands came down hard on the bench, blood spattering across the blue residue in the tube. The world went to static, then black.

  Muffet could still hear the click, click, click, even as the room erased itself behind her.

  And somewhere in the dark, the Spider laughed.
