The small hand tightened around mine. "Now you can remember me," the child whispered, its fingers holding on with a strength that didn’t belong to someone so young. My right palm began to ache, as though two parts of me had recognized each other before my mind could understand why.
"Who are you?" I asked.
The darkness offered no answer, but the monitors suddenly flickered to life, illuminating the metal table and my mother standing several steps away. She stared at my hand with absolute horror, then warned me not to move or speak to whatever was holding me. When I looked down, I saw my arm, the silver markings beneath my skin, and empty space where the hand should have belonged to a body.
I pulled free, and something moved behind the monitors.
My mother seized my sleeve. "We have to get out of this room."
"Not until you explain what’s happening."
"There’s no time."
"You’ve said that three times since I found you. I’m starting to think time isn’t the problem."
A monitor shattered behind her, scattering glass across the floor. She flinched, then gave me a look so familiar that I almost forgot where we were; it was the same expression she used whenever I refused to end an argument. This time, however, she sounded frightened enough to make me follow her without another word.
A narrow doorway had appeared between two metal panels. My mother pressed her palm against its shifting silver symbols, and the wall opened onto a corridor illuminated by weak emergency lights. We hurried through, and the passage sealed behind us, leaving only the distant sound of dripping water.
I turned toward her. "The recording said the original subject wasn’t the child. The voice said the same thing, and now something invisible is holding my hand. What did they put inside me?"
"Nothing," she replied.
"Then explain the two signatures."
She stopped walking before answering. When I was born, she explained, the machine had registered two responses: one followed my body, while the other appeared within the structure itself, as though something on the opposite side had reacted to my existence. The researchers couldn’t separate the readings, and every attempt to investigate the second response made the chamber increasingly unstable.
"Was that child the second response?"
"I don’t know. I saw a child during the first activation, but I couldn’t tell whether it was the source, a manifestation of the response, or something the structure created afterward."
Her answer was painfully precise, and I believed she was telling me everything she knew. That didn’t make the situation any less disturbing, especially when I remembered the child’s accusation that I had taken its place.
"Why did you leave me?"
Her expression softened. "I didn’t leave you, Veyric. I was taken away from you."
"By whom?"
She hesitated. "Your father."
I stared at her, waiting for an explanation, but she continued toward a recessed panel in the wall. After pressing several symbols in a sequence I couldn’t follow, she opened a narrow compartment and removed a metal cylinder and a folded piece of paper. Her hands trembled as she unfolded it, revealing an old photograph of three people standing outside the facility.
My mother stood beside the stranger, who looked considerably younger than when I had met him. Between them was a man holding a baby, his hand resting protectively against the infant’s back. I didn’t recognize his face, but something about his eyes and jaw felt strangely familiar.
"Who is he?" I asked.
"Your father."
The corridor seemed to tilt as I studied the photograph again. On its reverse, someone had written a date followed by a message: THE FIRST RESPONSE IS STABLE. KEEP THE SECOND AWAY FROM HIM. I couldn’t tell whether the second response referred to the child, the presence beneath the city, or something that had existed alongside me since birth.
"Where is he now?"
"I don’t know."
This time, I believed her.
A distant impact shook the corridor, and the emergency lights flickered as silver markings brightened along the walls. Pain pulsed through my right hand in rhythm with something deep beneath the floor, prompting my mother to seize my wrist and warn me against synchronization. She told me to focus on something that belonged to me rather than the structure.
I thought of Nyelle standing beside me before I entered the station, refusing to let me face the danger alone. I remembered her determination, the way she argued when frightened, and how she kept moving even when neither of us knew what waited ahead. Gradually, the pain in my hand eased, and my mother released a shaky breath.
"Good," she whispered. "Hold on to that."
Before I could ask what she meant, a crack appeared between the metal panels behind us. Pale blue light seeped through the opening, forming the outline of a small hand, and a child’s voice emerged from the other side.
"Mom? I’m cold."
My mother closed her eyes. "Not again."
The voice sounded younger than the child we had encountered, carrying the uncertainty of someone who had awakened alone. My mother admitted that the first time she heard it, she had believed I was crying, even though the baby in her arms had remained silent. The researchers had called the second response an echo, an imprint created by the structure that could supposedly be studied without risk.
"But when I approached the chamber," she continued, "it called me by name."
"What did it say?"
She looked at me. "It asked why I had left it alone."
The words sent a chill through me. Before I could question her further, something struck the other side of the wall three times, and the metal bowed inward with each impact. My mother dragged me down the corridor as the panel tore open behind us, releasing a wave of cold air that smelled of wet stone and something ancient.
I glanced back once and saw a small figure standing in the opening, its face hidden by darkness. It didn’t chase us; it simply watched, then raised one hand as my right palm answered with a sharp pulse of silver light.
The System appeared.
[ORIGIN RESPONSE DETECTED.]
[LINKAGE: PARTIAL.]
[WARNING: EXTERNAL RESPONSE IS NOT CONTAINED.]
My mother pulled me around a corner and into a low chamber, then slammed a metal lever beside the entrance. A heavy barrier descended behind us, cutting off the corridor, and we stood in darkness for several seconds, breathing hard. When I finally turned toward her, I remembered the photograph and the message about my father.
"You said he took you away. Where did he take you?"
"Somewhere the structure couldn’t reach."
"Then why did you come back?"
Her face paled. "I didn’t."
She reached inside her coat and removed a small object wrapped in cloth. Unfolding it revealed a metal ring engraved with the same three-circle symbol I had seen on the photograph and the stranger’s device. Its surface felt unnaturally cold, and a narrow gap interrupted the outer circles as though the design had never been completed.
"Your father gave me this before the facility collapsed," she explained. "He said that if the structure ever responded to you again, I had to find the original chamber and destroy it."
"Why didn’t you?"
"Because I tried. Every time I brought it near the chamber, the structure reacted before I could get close enough."
My right hand warmed, and the gap in the ring began to glow. My mother snatched it away, warning me not to let it touch my skin, but we both knew the object was already responding to me. For the first time, she looked less like someone hiding a secret and more like someone whose carefully constructed plan had finally failed.
"Find your sister," she said.
I frowned. "Nyelle is outside the station."
"No." She gripped my shoulders. "The second response was suppressed twenty-four years ago, but it was never destroyed. Since the blackout began, the structure has been trying to restore it."
A heavy knock sounded behind the barrier, making her flinch. Another followed, and the System appeared between us with a message that seemed to drain the remaining color from her face.
[SECONDARY RESPONSE: ACTIVE.]
"It’s too late," she whispered.
The barrier shuddered, and a final notification appeared.
[SUBJECT 02: LOCATION CONFIRMED.]
Then Nyelle’s voice came from the other side.
"Veyric, open the door."
My mother seized my arm before I could move. "That isn’t your sister."
I stared at the barrier, remembering every argument, every laugh, and every moment I had spent searching for her since the world changed. I knew Nyelle’s voice better than almost anyone’s.
And the voice behind the door sounded exactly like her.
