As Andy stood in front of the heavy reinforced door, he couldn’t help but think back to the endless hours of work and study it had taken to get to this point. He quickly made a few adjustments on the Echochron, programming a small subroutine into the door’s system. The code would allow him to manipulate the door remotely, ensuring that he could move deeper into the area without having to worry about a sudden security lockout.

  The small, almost imperceptible hum of the program working settled in his mind like a calm heartbeat. With a final swipe of his finger, the last of the barriers on the door’s security systems dissolved.

  The air was thick with dust, and the faint smell of decay lingered in the air. The light from his torch flickered across the grimy walls, casting long, eerie shadows that seemed to twist and writhe in the half-darkness. Andy’s boots clicked softly against the concrete floor, the sound echoing strangely in the emptiness.

  This was no ordinary section of the underground. He knew that much. He was entering an area that hadn’t seen human eyes in centuries, if not longer. A place where time itself seemed to have frozen. The Severing had done its damage, disrupting everything. There were few records left, fewer people who even remembered what had happened. People spoke of a war, the War of Unmaking, but no one knew what it was about. It had wiped out civilization, stopping everything in its tracks. The war brought the machines; the humans working with the machines, and even the natural flow of time to a standstill. How long had it lasted? A day? A week? No one really knew. All they knew was that everything came to a grinding halt on that day—the day the world ended.

  Though buried deep within Andy’s mind, the memory of that unspoken catastrophe became impossible to ignore as he ventured further into the forgotten underground corridors. That event irrevocably changed the world, and the people who had once lived and thrived in these spaces disappeared. The machines that had once hummed with life and purpose were now broken, derelict shells.

  As Andy stepped further into the abandoned hallways, he felt the weight of the lost history. This place had seen the last moments of an entire civilization, and here he was—standing in the ruins, as if nothing had ever happened. But everything had happened. The Severing had torn the fabric of society apart. And now, decades or even centuries later, the world was still recovering, still rebuilding in its own way.

  Andy took a slow breath, his mind wandering back to his work, his thoughts circling back to the Echochron. It was an important tool, something he had created to understand the lost technologies of the past and perhaps even to piece together the truth about what had happened all those years ago.

  But right now, it was more than just a tool. It was a connection to something bigger, something beyond the fractured world he lived in. The deeper he went into the underground, the more questions piled up—about the war, about the Severing, and about his place in all of it.

  For now, though, he had to focus. He had come this far for a reason. The salvage, the answers, whatever secrets this place held—they were all out there, waiting to be uncovered. And Andy, with the Echochron as his guide, was determined to find them.

  As Andy pushed deeper into the forgotten corridors, the tension built inside him. His breathing slowed, uneven at first, before it became more frantic, more ragged. The surrounding space seemed to grow more oppressive with every step. The walls, once distant, now felt suffocating. Each shadow, each flicker of light from his torch, seemed to dance and twist in ways that made his heart race.

  It was the silence that got to him first. There was no hum of old machinery, no distant echo of footsteps or movement—just an overwhelming stillness that wrapped around him like a vice. He could almost feel the weight of time itself, pressing down on him, the knowledge that he was walking where no human had been in so long.

  His chest tightened.

  Andy had spent years studying the underground networks, mapping out every path, every corner, every detail. But this—this was new. This was an unknown. And it wasn’t just the unfamiliarity of the place that caused the panic to creep in. It was the fear of the depths. The fear of the dark places beneath the city, the places where the bio-mutants still lurked, silent but waiting. The places that had seen the end of the world—the Severing.

  He paused, trying to steady his breathing, but it wasn’t enough. His hands shook, and the panic hit him in waves. It was like a weight inside his chest, pulling him down, threatening to swallow him whole. His vision blurred for a moment, the walls feeling like they were closing in, the ceiling pressing down on him.

  Just breathe. Just breathe, he told himself, but the words felt hollow. His throat was dry, his pulse pounding in his ears. He had dealt with this before, when he first started coming down here. It had been a slow process to even step foot in these dark tunnels, to push past the memories of the sewers during the Bastion attack. But this was different. This was the unknown. This was something far worse than anything he’d faced in the city streets.

  If you come across this story on Amazon, be aware that it has been stolen from Royal Road. Please report it.

  He thought of Terra, of the time they’d spent hiding from the chaos, and how she had helped him survive those early days after the Bastion attack. She had been his anchor, a reminder that there was still some light in the world, some warmth. But Terra wasn’t here now.

  Focus, Andy told himself, forcing his hands to steady. He looked down at the Echochron, his fingers gripping its edges to ground himself. It had always been his way of connecting to something solid, something real. The codes, the systems, the design—it gave him purpose. And now, more than ever, he needed that sense of control.

  He forced himself to take a few deep breaths, slow and measured, pushing past the rising panic. With the Echochron in his hand, he walked again, each step heavy but determined. His mind was a blur of thoughts—salvage, components, the lost technologies that could change everything.

  He had to proceed. He was aware of that. There was nothing else he could do. His grandfather had always told him that the world didn’t stop, and neither could he. But as he stepped further into the dark, his stomach churned, and the panic returned with a vengeance, threatening to pull him under.

  Focus on the goal, he reminded himself. You need to find what’s down here. The components. The knowledge. That’s what matters. That’s why you’re here.

  Andy fought to push the fear aside, to keep his mind on the task at hand. The further he went, the more difficult it became to ignore the creeping sensation in his chest. The panic was genuine, but so was the need to push through, to face whatever lay ahead, whatever answers the underground might hold. He wasn’t just looking for parts—he was looking for answers. For the key to unlocking the mysteries of the past.

  With one final breath, Andy squared his shoulders and kept. He would conquer this fear, one step at a time.

  The sounds in the dark were getting louder now. Small scuttles, the scrape of something moving across the floor—impossibly quiet, yet so close that Andy could almost feel the vibrations in the air. His heart rate quickened as he strained to listen, but the fear swelled in his chest, drowning out the logic of his thoughts.

  Bio-mutants… The words echoed in his mind as he squeezed himself into a hidden recess. Andy had never used this alcove before. It wasn’t one of the usual hiding spots he had mapped out in the maze of tunnels under the city. This area was unknown, unfamiliar, and that alone sent an extra pulse of panic through him. He had studied the underground—he knew its twists, its hidden passageways, and where to expect danger. But this was different. This was uncharted territory, the place where anything could lurk in the shadows, and he didn’t know what to expect.

  He pressed himself further into the narrow recess, feeling the cold stone against his back, his breath shallow and quick. His heart beat in his throat as the sounds grew closer, more distinct now—scraping noises, the soft padding of feet too quiet to pinpoint, the unmistakable sound of something hunting.

  Stay still, he reminded himself. His hands gripped the Echochron tightly, the weight of it grounding him, connecting him to something real amid the rising panic. He closed his eyes and focused on the hum of its circuits, trying to push away the overwhelming sense of dread clawing at his chest.

  The echo of his breath in the darkness felt louder with every passing second. The hairs on the back of his neck stood on end. He couldn’t tell how many were out there—he couldn’t even trust his senses. Was it one creature or more? His mind raced through the possibilities, but he knew that panicking now would only make things worse.

  The creatures in the underground weren’t like the ones in the wasteland—slow-moving, lumbering behemoths—they were fast, sleek, and deadly. They adapted quickly to their environment, making the dark their domain. The way they moved, so precisely, so controlled, was something out of a nightmare. He had to stay silent, stay as still as possible. If they were hunting, any movement would give him away.

  He strained to listen, holding his breath, but the sounds were fading now. His muscles ached, his hands growing clammy around the Echochron as the tension built. Was it the creatures circling? Or had he just imagined the whole thing?

  It was too quiet.

  The silence pressed in on him, heavy and stifling, and with it came the rising tide of panic again. His mind spiraled—had they passed by him? Were they waiting just beyond the alcove? Waiting for him to make a sound, to move a single inch?

  Suddenly, a low hiss—almost too quiet to hear—broke the stillness. The noise was close, so close. Andy’s heart skipped, and he stifled a gasp, fighting to keep his breath steady.

  He wasn’t alone.

  His body tensed, preparing to sprint if necessary, but his mind screamed, don’t move! Don’t make a sound. If he was going to get out of this alive, he had to remain invisible. Every nerve in his body screamed at him to flee, but he knew running would be suicide.

  Focus. He focused on the hum of the Echochron in his hands, its faint energy flowing through him, the only thing grounding him to the moment.

  The hiss grew louder, followed by the scrape of claws against stone, unmistakable in the heavy silence. The sound was coming closer, and Andy’s heart raced faster, drowning out everything else. He swallowed hard, trying to steady his nerves, but the pressure was unbearable.

  And then… nothing. The scraping stopped.

  His breath caught, his ears straining to catch the faintest hint of movement.

  He had to stay calm. He had to be patient. The creatures were here, but they hadn’t found him yet. They might not even know he was there.

  But even in the dark faced with the unknown, a part of Andy knew—he wasn’t alone down here.
