The roar tore through the cavern again, closer, vibrating through the stone beneath Caleb's feet. Dust cascaded from heights above. Whatever made that sound was massive, and it was moving. Fast.

  Run!

  He spun on his heel, his only thought to flee back through the tunnel he’d come from, back toward the memory of sunlight.

  Heavy footfalls thundered from the darkness behind him, each impact a drumbeat of raw mass slamming into stone. They were close. Too close. The sound built with terrifying speed—a freight train of muscle and bone hurtling through the black.

  Caleb pulled, panicking as he tried to concentrate Stamina into his legs for a desperate [Dash] toward the tunnel. The energy began to pool, his muscles coiling with compressed power—

  A displacement of air rushed into his back, a wash of fetid heat and the stench of rot so thick he tasted it.

  Crumb!

  He threw himself sideways in a graceless dive, releasing the Stamina before he could use it. Claws shrieked through the space where his head had been a heartbeat before. The sheer force of the creature's passing sent him tumbling, his shoulder slamming into the cavern floor. He rolled, came up in a crouch, his spear somehow still in his grip.

  His perception beam snapped toward the threat on full blast, pushing through this extra complication and everything beyond. A gargantuan obstruction filled the cavern. The creature's aura blazed a nauseating crimson-black that felt of crushing rock and tasted of the grave. Its core nature felt so deeply repulsive, Caleb's gorge rose.

  His perception struggled to resolve the spatial fuzz, finally locking onto its horrifying scale. The mass had the general structure of a goblin, but magnified—a dense concentration of power that pulsed over eight feet high at its apex. Four limbs extended from the central mass, ending in what his perception registered as sharp, dangerous points. The appendage that had to be its head swiveled, and its entire vicious intent narrowed, drilling into him like a spike.

  The creature shifted position with deliberate, calculated movements, angling its colossal bulk to block the tunnel mouth. Each step was purposeful, patient. It was sealing his only escape route.

  Then it charged.

  Caleb's body reacted before his mind could process the danger this time. He channeled Stamina through his legs, the energy surging from every cell in a systemic draw. The power concentrated, compressed, then he exploded away. [Dash] carried him to the left in a blur of motion.

  A sound like grinding boulders erupted where he'd been standing, as its talons scored deep gouges into the ground. A heavy tremor pulsed up from the stone, rattling into the soles of his boots.

  Its head snapped toward him with preternatural quickness. It lunged again. He perceived the head-mass elongate as its maw opened wide. A wave of carrion-stench, hot and suffocating, washed over him. Caleb triggered another [Dash], this time backward. Heat seared through his legs as the Stamina discharge left his muscles burning. The technique wasn't meant for repeated use—each activation was a controlled detonation that built up damage in its wake.

  His back hit a stalagmite. The beast's teeth snapped shut inches from his face, but he rolled right, the creature's follow-up swipe missing by a hair's breadth.

  Can't keep this up! Two dashes and my legs are already cramping!

  Caleb's Stamina reserves were plummeting. Each full-power [Dash] was a fire hose blasting at a thimble-sized problem, and he'd need every scrap of energy to survive this. There had to be another way.

  He recalled his initial tries at the technique before mastering the correct form. That shorter, incomplete burst where he'd failed to maintain the energy thread through the entire movement. They'd been failures then, but...

  The creature feinted left, then struck right. Instead of a full [Dash], Caleb channeled a fraction of the Stamina, releasing it almost immediately. The result was a two-yard hop backward—sufficient to avoid the worst of the strike, though the beast's claws still scraped his cuirass, failing to penetrate.

  Less distance, but lower cost. And I can control the direction better.

  He began incorporating the abbreviated dashes into his movement pattern. A quick hop left to avoid snapping jaws. A backward skip to dodge a backhand swipe that would have shattered his ribs. The micro-movements let him stay mobile without destroying his legs or depleting his reserves as quickly.

  The creature snarled, and its assault grew wilder, as if it were confounded by prey that refused to hold still.

  Then it shifted position, aligning itself perfectly between Caleb and the cavern's far end. His perception beam, still panic-blasting at full power, exposed what was beyond.

  A yawning void gaped in the far wall, an opening easily fifteen yards across. The ground in front of the opening made Caleb's blood freeze. His perception registered a cluttered, uneven floor, littered with countless small, hard shapes. They were piled in drifts, scattered like debris. The sheer number of them, and the faint odor of decay coming from that part of the cavern, painted a horrifying picture. Bones. A graveyard of them.

  He remembered the creature hadn't come from that direction, and a terrifying truth settled in. This cavern wasn't this monster's personal den. He'd stumbled into a shared space, littered with carrion like some apex predator's buffet table. And judging by the sheer size of that dark opening, the thing he was fighting wasn't necessarily the biggest predator here.

  The intense pressure behind his eyes snapped him back to the immediate danger. He was wasting massive amounts of Mana, his perception beam blazing past his target to map useless stone.

  He throttled the beam back immediately, narrowing its focus to just the creature's body. The elongated spatial beam vanished, replaced by a simpler awareness of the creature's position and movement. A dull, lingering ache replaced the stabbing pain behind his eyes, and his thoughts cleared of the mental static. The Mana drain slowed, but the state of the reservoir in his core made one thing very clear: he was running out of time.

  Stupid! Wasteful! Gone for nothing! Stupid, stupid—focus!

  The creature circled, and Caleb matched its movement, keeping his damaged left side away from those claws. Time to go on the offensive. He couldn't dance forever.

  He waited for an opening—the brief moment when the creature shifted its weight to change direction. His [Breaching Thrust] lashed out, aimed for a point of articulation he perceived in its forward limb.

  The spear tip caught something incredibly dense and skittered off harmlessly. The jarring impact sent painful vibrations up his arms.

  It twisted, presenting a section of its upper torso toward him and pulling back its arms. When he tried another thrust, aiming for its flank, the creature simply angled its body so the spear met what felt like an impenetrable mass on its chest.

  Is… is it learning? This is bad.

  His next attack confirmed it. The creature not only positioned itself to deflect his spear but used the momentum of his thrust against him. As he extended for the strike, it stepped into it, letting the spear slide along its armor while bringing its head around for a snap at his exposed arm.

  Only a desperate micro-[Dash] saved him from losing the limb.

  Worse, the creature was adapting its tactics. Instead of charging blindly, it began using the environment. It ignored him, turning to the cavern wall and raking it with its huge claws. Rock groaned and splintered. A cascade of falling masses registered in his perception. He heard the whistle of their descent and the heavy thud as they impacted the floor around him. Caleb had no choice but to waste a precious burst of Stamina on an unplanned [Dash] to avoid being crushed.

  His confidence cracked. The smaller goblins had been manageable. Their auras were thin, fragile things that barely registered as Low-Red in his perception. This creature felt different. Its spiritual signature pressed down on him like magnified gravity, thick and smothering. High-Red. He'd never perceived any beast so deeply saturated in the Body Triad at his tier. The thing must have been hunting in these caves for years, and every moment showed it.

  The creature’s testing lunges ceased. With a roar that shook more dust from the ceiling, it abandoned patience for a full-bodied assault. Caleb tried to [Dash] left, but his placement among the stalagmites limited his options. The creature had planned this.

  He managed a partial dodge, but a claw caught him anyway. The impact lifted him off his feet and hurled him against a stalagmite. His pack's contents helped cushion the collision, but his cuirass, already damaged from the earlier fights, split like paper. A tearing impact ripped through his side. A trio of distinct, searing pains carved deep as claws found flesh.

  Caleb hit the ground hard. A hot, wet sensation spread instantly from the wound, a terrifyingly rapid flow of his own life. He pressed his hand to the cuts, feeling their depth. The wounds were survivable, but bad. Terrible.

  Can't run anymore. Can barely stand.

  He dragged himself backwards, away from his tormentor. Its approach turned leisurely, almost casual. Why rush when your prey was cornered and bleeding out?

  Caleb's beam tracked its movement as it stalked wide, cutting off any escape route. It was backing him into a corner of the cavern, pinning him to the unknown pit. Behind him, the vast, dark opening to the boneyard gaped like an open grave, a constant, terrifying presence at his back. The creature was simply trapping him, but the location made his skin crawl. He was being crushed between an immediate threat and the potential of a far greater one.

  No. Caleb struggled back to his feet.

  His defiance triggered a cascade of memories—Katie at her soccer game, hair in a ponytail, her face a mask of fierce concentration. Jack holding up a drawing, his smile proud and serious. Evelynn’s sleepy grin over morning coffee. He had chosen [Perfect Memory] to preserve them. He would not let them be erased.

  The tactical choice became an emotional vow. A raw, hard certainty settled in his heart, displacing the fear.

  I didn't lose everything just to die in this cave!

  The memory shifted—his legs overloading with Stamina during training in the forest. The sensation of holding too much power, feeling his muscles tear under the strain. He'd released it then, terrified of the damage.

  But damage could be a price worth paying.

  The creature came then, a slowly building charge to finally end its wounded prey. Caleb had one chance. His normal thrusts couldn't penetrate that hide, not with his current strength. He needed more power. Much more.

  As the beast closed the distance, Caleb pulled. A desperate, systemic drain of each drop of Stamina he could muster. The energy flooded in from every corner of his body.

  He channeled it all into his arms, shoulders, and back. Then, violating every rule of safe energy manipulation he knew of, he held it there.

  His muscles screamed. It was the feeling of his own frame tearing itself apart from the inside out; the cells burning with a strength they were never meant to contain this long. His body was a drum, stretched taut, ready to burst. He held the energy, a human bomb about to explode.

  Holding it was an agony he hadn't felt since being thrust into this world, but he refused to yield.

  The creature was five yards away. Three. Its jaws opened wide enough to take his head off. The world seemed to slow, the creature's advance turning into a series of distinct, horrifying snapshots.

  Now!

  Caleb thrust with everything: the Stamina, his will, his rage, his desperate need to survive. The spear moved faster than thought, faster than anything he'd managed before. The overloaded Stamina transferred from his ravaged muscles into the spear shaft, turning the simple iron tip into something more.

  The attack met the creature's charge head-on.

  His simple spear tip detonated on impact, the uncontrolled force punching through the creature's armored hide, ripping through bone and muscle. A gout of steaming fluid erupted from the monster's far side, and the stench of blood and viscera filled the air.

  The kinetic force of the blow was undeniable as the beast's forward charge was violently reversed. Its immense body lifted from its feet and hurled backward through the air, ripping the spear from Caleb's grip. It crashed against the cavern floor five yards away with a wet, final thud.

  The recoil was just as brutal. A sickening crack resounded in the cavern as the unrestrained energy slammed back into his right arm. Bones shattered from the wrist to the elbow. A scream of pure agony was torn from his throat.

  He staggered back, his vision whiting out from the pain. The Stamina overload’s fierce backlash surged through him. It was the searing cramp from his failed [Dash] experiments, but a dozen times worse, consuming his entire upper body. The muscles in his arms and back felt like they had been seared to the bone, leaving behind a deep, spasming ache. His legs, scoured of their last reserves to fuel the attack, trembled violently and threatened to give way. The warm, slick flow from the wounds in his side intensified, and every breath was a hot agony. But he did not fall.

  Caleb forced his legs to lock, planting his feet on the stone floor. He stood there, swaying, in the sudden silence. His right arm hung uselessly at his side, a broken ruin. Blood dripped from his torn flesh, forming a small pool at his feet. He was bleeding out, disarmed, and barely remained conscious. But he was alive. And he was standing.

  Did it, he thought, the words a faint whisper in the storm of his pain. Killed it. Now just…

  A scraping sound came from across the cavern. Then another. The distinctive note of claws on stone.

  With the last dregs of his Mana, Caleb sent out a final, wavering perception pulse. The remaining goblins were creeping forward from various tunnel entrances. Three of them. They moved cautiously, aware the larger beast was dead but unsure if its killer still posed a threat.

  They kept their distance, postures a mix of hunger and caution.

  Caleb watched their spatial signatures advance. His spear lay somewhere in the darkness near the corpse. He couldn't properly wield the knife at his belt with a shattered arm and spasming left hand. He couldn't run. All he could do was stand his ground and watch them come.

  The scraping grew closer.
