Mike walked through the tunnel with measured steps, his mind churning over everything Harrow had revealed. The conversation felt like fragments of a fever dream. His casual admissions of surveillance, his impossible demonstrations of power that defied reality.

  'A new sense. A place deep underground. A path to power.'

  Mike flexed his fingers, rolled his shoulders, examined his body as he walked. It felt strong and alert, but fundamentally unchanged. The absence of hunger struck him as odd though. His mouth wasn't dry, his stomach wasn't cramping with emptiness. It should have been impossible to go that long without sustenance, especially after everything he'd experienced. But other than that, he was a little disappointed that he couldn't find anything different at all.

  Yet if his body remained stubbornly familiar, the tunnels around him told a different story entirely.

  The increasing darkness of the passages revealed the true extent of the underground transformation with every step forward. The changes that had occurred during his week of unconsciousness were staggering. Walls that should have been bare concrete now showed signs of organic modification that defied explanation. Crystalline growths erupted from the surfaces in patterns that seemed almost deliberately beautiful, casting faint bioluminescent glows that painted his path in ethereal blues, greens, and purples.

  Mike traced his fingers along one of the formations as he passed, feeling the cool, smooth surface beneath his palm. The crystal pulsed faintly at his touch, its inner light brightening for just a moment before settling back into its steady rhythm.

  The tunnel gradually widened as he walked, the crystalline growths becoming more elaborate, more densely packed. Some had begun to bridge across the ceiling like luminous ribs, transforming the passage into something that felt less like infrastructure and more like the interior of some vast, sleeping organism.

  Twenty minutes into his journey, the organic tunnel opened into something more recognizable, though no less changed.

  A metro station stretched before him like a concrete graveyard, dotted with rusted benches, faded advertisements, and graffiti that spoke of decades of neglect. Crystalline formations had invaded here too, climbing the support pillars like ivy and spreading across portions of the walls in geometric cascades. And there, dominating the far end like a monument to institutional power, half-consumed by glowing mineral growth, stood the familiar sight of sealed metal doors.

  Looking at the massive barriers Mike had a sudden thought. If his body felt unchanged on the outside, maybe the difference lay somewhere deeper... He wanted to test Harrow's claims about his transformation.

  Mike closed his eyes and steadied his breathing, trying to reconnect with whatever energy had flowed through him at Worth Street Station. He focused his concentration into his right hand, visualizing power gathering in his muscles and bones. The memory of that transcendent moment was vivid: the way strength had built like pressure in a sealed container before exploding outward with devastating effect.

  For a few seconds, he thought he felt something. A tingling warmth spreading up his arm, subtle electricity moving through his nervous system. It might have been real, or wishful thinking fueled by Harrow's promises.

  He drew back his fist, channeling every ounce of physical strength he possessed, and launched forward with a primal scream that echoed through the empty station.

  He put everything into the punch. His knuckles cracked against unyielding metal with a sound like breaking bones.

  Pain shot up his arm in lightning-bright waves. The door didn't even vibrate under the impact, didn't show so much as a scratch on its surface. The massive barrier stood perfectly still, almost mocking him with complete indifference to his efforts.

  Nothing happened.

  Mike cradled his aching hand against his chest, feeling both physical agony and profound deflation. The skin across his knuckles was torn and bleeding, already beginning to swell. His entire arm throbbed with pain that made him grunt and curse.

  The failure was complete and humiliating.

  He'd believed, for just a moment, that Harrow's promises might be real. That whatever transformation he'd undergone during those seven days might have given him power to break through barriers that normal humans couldn't even dent.

  Instead, he felt grateful that nobody was there to witness his stupidity.

  His body hadn't changed at all. No sudden surge of strength when he'd punched the door, no obvious physical transformation like Harrow had suggested with his refined mannerisms.

  If Sam had seen this pathetic display, Mike thought with bitter amusement, he'd never let it go. I can practically hear his laughter echoing through the tunnels.

  ‘Sam?’

  The moment his friend's name formed in his conscious mind, something fundamental shifted in his perception.

  A small dot of light appeared in his mental map of the tunnels, faint but unmistakable, like a star piercing through clouds.

  The sensation was so unexpected that he stopped moving entirely, his curses about his throbbing hand dying mid-syllable.

  His heart began to race, not with fear but with a strange cocktail of confusion and wonder. The faint dot in his mind sharpened from a vague glow into something with defined edges and presence. He closed his eyes to focus on his mental map with desperate intensity. Visualizing the map of the metro he'd built, he could detect the exact location of the dot of light now.

  He was certain of it: this dot of light represented Sam. The dot was at the exact position where Sam had been left behind, his body wracked with infection. And if Sam's body had been going through the same transformative process as his own, there was a chance he wasn't dead after all.

  A surge of hope filled his heart. For once, he was starting to see light at the end of the tunnel.

  He opened his eyes again and looked at his bloody hand. Back at Worth Street Station, the explosive surge of power he'd felt was like grabbing hold of a live wire; electric, powerful, overwhelming. The way his energy had built up like water behind a dam before bursting through with world-shattering force.

  But this was different.

  This felt like breathing. Like something that had always been part of him. This simple dot of light in his mind felt like an extension of himself. Natural. Organic.

  Still, it was a bit inconvenient to have the dot of light in his mind only. He'd much prefer to have a visual indication in front of him directly, something like a compass that would show him Sam's direction no matter which way he turned, without having to constantly reference his mental map.

  'What if?'

  He focused his enhanced perception with renewed intensity, concentrating on that feeling of extension, of something that belonged to him responding to his will. Just a simple dot.

  ‘Just show me where he is.’

  Nothing happened.

  Mike's brow furrowed. He tried again, imagining a glowing point hovering in the air before him, pointing toward Sam like a star he could follow. The sensation remained stubbornly internal, locked behind his closed eyelids.

  Come on. You can feel him. Just... project it.

  A flicker of something passed through his peripheral vision, so brief he almost dismissed it as imagination. Then another. Faint threads of blue light, gossamer-thin, weaving through the air around him like luminous silk caught in an invisible current.

  Mike's eyes widened. 'Were these the same kind of energy Harrow had used?' That swirling blue smoke that had burned runes into concrete? But he didn't break his concentration. He wasn't entirely sure what the threads were or how he was generating them, but they felt connected to his intention somehow. He kept his focus locked on his objective: a visual marker for Sam's location. Just one dot. Something he could follow.

  The threads multiplied, dancing at the edges of his vision, moving with purpose he didn't fully understand. They spiraled and curved, forming patterns that flickered in and out of existence. Mike's pulse quickened, sweat beading on his forehead with the effort of maintaining his focus.

  And then, there.

  A single point of blue light materialized in the air before him, steady and clear. Not in his mind this time, but actually hovering in space about two feet from his face, glowing with soft luminescence.

  "Yes," Mike breathed, a grin breaking across his face.

  But even as satisfaction washed over him, another thought emerged. The dot was useful, sure, but what if he could see more? What if he could manifest his entire mental map, have it displayed around the marker for complete spatial awareness?

  ‘Don't stop now.’

  He maintained his focus on the blue dot representing Sam, but expanded his intention outward. The mental map he'd been building since the moment he'd entered these tunnels, every turn, every landmark, every detail catalogued with a photographer's precision, he wanted to see it rendered in light.

  The threads of blue light that had been drifting lazily around him suddenly intensified, multiplying into dozens, then hundreds. They wove through the air with startling purpose, connecting and intersecting, building something complex in three-dimensional space. Lines formed. Surfaces took shape. The threads braided together into tunnels, branched into passages, solidified into walls and platforms.

  Mike watched in breathless wonder as a complete holographic map assembled itself around Sam's marker dot. The entire section of the metro system he'd traveled through rendered in perfect detail: every curve of track, every support beam, every crack in concrete walls appeared with architectural precision. The translucent blue projection hung in the air before him, making his mental spatial memory seem crude by comparison.

  "Jesus Christ," Mike whispered, his voice barely audible in the empty station.

  The three-dimensional map hovering before his eyes was breathtaking. His injured hand hung forgotten at his side, pain rendered irrelevant by the sheer impossibility of what he was experiencing. He felt like a kid who'd just discovered he could fly, or read minds, or turn invisible. The practical applications were obvious, but right now, in this moment, what mattered was the pure wonder of it.

  Those threads of light, what the hell were they? How had he controlled them, shaped them into this intricate projection? He didn't understand the mechanics, and couldn't explain the process even to himself. But there wasn't time to analyze it now. Not when there was so much more to test.

  Sam's dot held steady in one of the tunnels displayed before him, and almost without thinking, Mike focused on another person.

  'Dana?'

  This story has been stolen from Royal Road. If you read it on Amazon, please report it

  A new presence illuminated in his awareness instantly, and Mike actually laughed, a short, disbelieving sound that echoed off the empty platform. Holy shit. It's real. It's actually real.

  Dana's marker appeared in a different section of the tunnel system, fainter and further away than Sam's but equally steady. The distance felt significant, maybe several stations removed from his current position.

  He tested the ability again, his excitement building.

  'Jake?'

  A third point of light appeared in his mind, weaker still but unmistakably present.

  Mike's grin widened despite himself—wait.

  He realized that Sam's dot had disappeared from both his awareness and the holographic map the moment Jake's appeared. Focusing on Sam again, his marker returned but Dana's vanished.

  ‘So the limit is two people at the same time.’

  The limitation was oddly reassuring, proof that this was real, not some fever dream or wishful hallucination. Real abilities had limits. Real powers came with costs and boundaries. The practical side of his brain kicked in, cataloging the ability's parameters like he would a new camera or piece of equipment. He'd need to test it more, push the boundaries, understand the costs and limitations.

  Mike stood in the middle of the abandoned platform, ignoring the blood dripping from his knuckles, and allowed himself a moment of pure wonder.

  This was his. This ability, whatever it was, belonged to him in a way nothing else ever had. Not external power borrowed or gifted, but something intrinsic. An evolution of who he already was: someone who'd always possessed exceptional spatial awareness, whose gift for navigation had kept him alive.

  Now that gift had become something more. Something extraordinary.

  Mike wanted to test everything, to push the boundaries of what he could do, to explore every facet of this new sense like a child with a new toy. But he forced himself to slow down, to be methodical. He needed to understand it properly.

  Starting with the obvious question: what else could it do?

  The hologram in front of him wasn't just about dots representing people, but it showcased the entire topology of everywhere he'd been, rendered with such crystalline clarity that it made his previous spatial memory feel like cave paintings compared to high-definition photography.

  He could zoom in on specific locations with microscopic detail: examining warning signs on fences, studying exact patterns of rust stains on abandoned train cars, observing the symbols Harrow had burned into tunnel walls. Everything was there, preserved with a crystalline precision that seemed to exist outside normal memory.

  Mike experimented with growing fascination, rotating his viewpoint like manipulating a 3D model. He could look at the tunnels from above, below, any angle he wanted. Distance and physical barriers meant nothing. He could examine areas he'd visited days ago with perfect clarity as if standing there in person.

  The control was intoxicating. He traced paths he'd taken, examined minute details he'd barely noticed at the time: graffiti on walls, cracks in support beams, the specific pattern of bloodstain scattered across platforms.

  'I could get lost in this forever,' he thought with genuine wonder. Just cataloging, understanding every inch of this place.

  Mike pushed further, trying to expand the three-dimensional rendering to encompass more territory. His breathing had grown slightly heavier without him noticing. A faint pressure was building behind his eyes, subtle enough that excitement overrode any warning signals his body tried to send.

  The map expanded, incorporating more tunnels, more stations, more...

  But even as he marveled at the growing detail, something deeper stirred beneath the surface. An intuition that whispered of hidden layers, of capabilities he couldn't yet grasp. Like standing at the base of a mountain and suddenly realizing the peak disappeared into clouds so high he couldn't see where they ended.

  He couldn't reach it yet. Wasn't experienced enough, wasn't skilled enough to climb that high. But it was there. Waiting.

  The realization hit him with startling clarity: this ability had depths he couldn't even begin to fathom. What he was doing now, tracking people, manifesting maps, might only be scratching the surface of what was possible. The thought filled him with equal parts excitement and humility.

  How much more was there? How far could this—

  His knees buckled without warning.

  The holographic map shattered like glass, fragmenting into chaotic threads of light before dissolving completely. Mike collapsed onto the platform floor, catching himself with his good hand before his face could hit concrete. His vision began to blur at the edges, the enhanced visualization that had seemed so wondrous moments before now felt like trying to drink from a fire hose: too much information flowing too fast for his human brain to process without consequence. His body felt simultaneously overstimulated and completely drained, like he'd run a marathon while solving complex equations.

  "Okay," Mike gasped, his voice shaky as he steadied his breathing. "Limits. There are definitely limits."

  He sat there for a long moment, letting his heart rate slow, feeling the fog of cognitive overload gradually clear. The disappointment was surprisingly sharp. He'd wanted to keep going, to explore every facet of this ability until he understood it completely. But his body had vetoed that plan with decisive authority.

  Still, even as exhaustion settled into his bones, Mike couldn't suppress the smile that crept across his face.

  ‘I just need practice.’

  Mike felt genuine awe wash over him, the kind of wonder he'd experienced the first time he'd looked through a camera lens and understood how it could capture truth. He'd been given something extraordinary, something that defied explanation.

  As he rested, Mike's thoughts drifted back to Harrow's mysterious chamber that had vanished from the tunnel. It gave him an idea for testing his ability's range and accuracy. He was still relatively close to where he'd exited, making it perfect for experimentation. If the tracking ability worked on everyone, then Harrow should appear just as clearly as his scattered teammates. The question was: where would Harrow's dot be?

  When he felt strong enough, Mike closed his eyes and focused his enhanced perception with deliberate intensity.

  'Harrow? Harrow?'

  The dot that appeared was much closer than those representing his distant teammates, still in the exact location he'd left. So why couldn't he see the entrance? Was it an illusion? That would fit. Harrow seemed to be a master of manipulation.

  Emboldened by this success, Mike's thoughts turned to something more personal, something that had been gnawing at him for some time now, filling him with desperate hope and dread in equal measure.

  He looked down at the faded ink on his hand, the phone number that had once represented possibility. That symbolic connection to Claire had faded long ago, but if his tracking ability could locate anyone he'd encountered...

  Mike closed his eyes and focused with desperate intensity, pouring every ounce of concentration into the effort.

  'Claire? Claire? Claire?'

  Nothing.

  No dot of light appeared in his mental map. No faint pulse, no distant glow, no indication that she existed anywhere within range of his enhanced perception.

  Mike tried again, concentrating harder, pushing his ability despite the trembling starting in his hands. The pressure built behind his eyes, his vision beginning to blur as he demanded more from power he barely understood.

  Still nothing.

  The absence was absolute and devastating.

  Claire's complete absence from his enhanced perception could only indicate one thing.

  Mike closed his eyes slowly, his face visibly aged by the conclusion he couldn't avoid. Claire was gone. He'd been carrying her memory like a talisman, using the possibility of finding her again as motivation to keep fighting when everything else seemed hopeless. Now even that small comfort was gone.

  'No.' It was too soon to conclude anything with certainty. He didn't even know how death would be represented by his ability. He needed to test other possibilities before understanding what Claire's absence might mean.

  Mike's throat tightened as other names came to mind.

  'Tess? Anna?'

  Their dots appeared instantly on his map, overlapping at the exact spot where he'd left them. Relief flooded through him so intense it made his knees weak. They were together. They were still there. He saw them die but he knew now that "death from infection" didn't mean death at all.

  He found himself hoping desperately that they would survive the transformation like he had, that the infection wouldn't twist them into something unrecognizable. The thought of losing them, of losing anyone else, felt unbearable.

  Mike looked into his memory and he tried focusing on the man in the train who'd been shot, bleeding out in those first chaotic moments. He didn't know his name so he pictured the man's face, his clothes, and the exact way he'd fallen, but nothing activated the tracking sense.

  'Was the name a mandatory condition?'

  In that case he won't be able to find anyone in the underground metro as he didn't know any name of the people who died during the attack.

  After a moment of reflection, one name came to him naturally, though it brought a sharp pain with it.

  Andreas. His father.

  It seemed almost disrespectful to use his father as a test subject, but he knew the exact location of the grave. It was the perfect reference point to understand how a deceased target would be represented.

  He closed his eyes, took a long breath and started to concentrate.

  'Andreas?'

  A tear slipped down Mike's cheek before he could stop it. The memory of his father's funeral surfaced unbidden: standing in the rain, watching the casket lower into the ground, feeling more alone than he'd ever felt in his life. He blinked hard, trying to focus through the sudden blur.

  A very faint dot appeared in his mental map, but not on the holographic projection of the New York metro floating before him. Of course, his map was rendered to show only the subway system. He'd need to visualize the cemetery to see his father's grave represented there.

  But he felt the dot. Extremely faint, weakened by distance, but present.

  Mike's breath caught. He could feel it. Could feel that connection spanning the miles between them, linking him to where his father rested. More tears fell, hot against his skin. For just a moment, across all that distance, across even the barrier of death itself, he felt connected to the man who'd taught him to see the world through a lens, who'd shown him how to find truth in composition and light.

  He wiped his face roughly, trying to compose himself. The test had confirmed something important: dead people could be located with his ability. Distance weakened the signal, but it was still there.

  ‘So why not Claire?’

  What other condition might be required beyond knowing someone's name?

  A scary thought occurred to him, there was a darker ending beyond death in those cursed tunnels...

  During his brief time in the bunker, he'd met Gerald, Tommy's grandfather, who'd been fiercely protective of his granddaughter. Mike had always wondered what happened after he saw the old man leap toward the catacombs, following some pull Mike couldn't understand.

  Mike concentrated, pushing his enhanced perception outward.

  'Gerald? Gerald?'

  A chill ran through his body as a small dot appeared in a completely dark region of his mental map.

  It was deep. Not just underground, but impossibly deep, perhaps a kilometer below the surface, far beyond any normal subway infrastructure. The location existed in a completely dark region of his mental map, in spaces that shouldn't exist beneath the city.

  ‘Why is he so deep?’ Mike wondered. ‘And why does that location feel so... wrong?’

  Gerald's position floated in a void of unknown space that felt fundamentally hostile in ways Mike couldn't articulate.

  What truly terrified Mike wasn't the depth. It was the sensation that came with that connection. It felt actively malevolent, like looking into an abyss that was looking back. The connection carried a temperature with it, a bone-deep cold that had nothing to do with physical chill. It was the cold of empty spaces and ancient things, of places that existed beneath the world where humans were never meant to go.

  Mike's hands began to shake. Disgust crawled up his spine like insects, making his skin prickle with primitive revulsion. Whatever Gerald had become, whatever was down there in those impossible depths, it was fundamentally wrong. Corrupted.

  He severed the connection with a sharp mental gesture, gasping as if he'd been holding his breath underwater. His heart hammered against his ribs. The lingering sensation of that cold, hostile presence made him want to scrub his hands, to wash away contamination that existed only in his perception.

  His father, lying peacefully in his grave, had felt like memory and loss and connection. Gerald, trapped in those terrible depths, felt like nightmare made manifest.

  'What does it mean to not find Claire at all?'

  The question haunted him, but Mike made a conscious decision to file it away for later. He couldn't afford to fall apart now, couldn't let grief or fear paralyze him when people were depending on him.

  He needed to reunite with his friends first, then figure out a plan to escape this nightmare.

  Focusing on Sam's position in his mental map, Mike noticed something that sent electricity through his exhausted body.

  The dot was moving.

  Sam was moving.

  A laugh burst from Mike's chest, genuine, surprised, filled with relief and excitement he hadn't felt since waking in Harrow's chamber.

  ‘Sam is alive.’

  And more than that, the connection felt warm. Nothing like Gerald's cold corruption. Sam's presence radiated something warm, something unmistakably vital. There was energy to it, a quality Mike couldn't quite name but recognized instinctively as life itself.

  The discovery transformed everything. Grief and terror gave way to focused determination. He had something concrete to work toward now, a mission that could channel his abilities toward something productive.

  With renewed energy, Mike set off through the tunnels, following his enhanced spatial awareness toward Sam's position. Each step felt lighter despite his exhaustion.

  The infection that should have killed him had instead given him exactly what he needed to find the people he cared about, to keep them alive. And that, more than any demonstration of supernatural power or promise of transcendent abilities, felt like the most important discovery of all.
