SUBJECT 01 MUST ARRIVE ALONE.
I read the message twice, hoping it would become less irritating the second time. It didn’t. "Absolutely not," Nyelle said beside me, and when I told her I hadn’t said anything yet, she gave me a look that suggested she knew exactly what I was thinking.
"Then stop being so predictable."
Under different circumstances, I might have appreciated the comeback. Unfortunately, the stranger’s device had just instructed me to abandon my sister before entering a place none of us understood, and the silver lines beneath the street were beginning to gather again.
The stranger examined the screen. "It’s an access condition, not necessarily a command." I stared at him, waiting for the explanation that would make that distinction useful, but he offered nothing more. The station remained marked by a pulsing silver point on his map, while another line flickered beneath the instruction, its characters breaking apart before we could read them.
"Whatever is down there, I’m not letting you go alone," Nyelle said.
"I wasn’t planning to."
"Veyric, don’t lie just because you think it’ll make me feel better."
I turned toward her. The message said I had to arrive alone, but it didn’t explicitly say she had to remain here while I entered. The stranger disagreed, warning that bringing her to the entrance might trigger a response, and I hated that his reasoning made sense.
"Would you prefer to discover the difference by watching her disappear again?" he asked.
His words struck harder than he intended. I remembered the silver circle closing around Nyelle and the helplessness of watching something I couldn’t understand interfere with her, but I wasn’t leaving her on an unfamiliar street while the world continued changing around us.
"Then we find somewhere safe," I said. "Somewhere we can return to if the station turns out to be another trap."
"And where would that be?" Nyelle asked.
I had no answer. The surrounding buildings were damaged, creatures were appearing in places that should have been empty, and even the structures that seemed to offer shelter had begun reacting to our presence. We couldn’t stay where we were, so I looked toward the station and made a decision I wasn’t entirely comfortable with.
"We go together until we know what the entrance requires."
Nyelle nodded reluctantly. "Then we’d better find out quickly."
---
We reached the transit station twenty minutes later, having avoided several streets where the pavement had collapsed and an intersection occupied by creatures resembling dogs with elongated bodies and blue light pulsing beneath their skin. We watched them from behind an overturned delivery truck until they moved away, noticing that they rarely crossed the silver lines running along the road.
Whether they recognized the lines or feared them, I couldn’t tell. Either possibility was better than discovering what happened when one of them decided to cross.
The station entrance stood at the end of a broad pedestrian plaza, its glass doors shattered and its metal frames twisted outward. The stairs descended into darkness that swallowed the weak daylight above, while a faded advertisement on the wall still promised faster journeys and safer commutes.
I almost laughed.
The stranger took out his device. The silver point on the map had expanded into a circle, and a thin line connected it to another mark farther underground, where the light flickered between silver and blue.
"The structure is responding to our proximity," he said.
"Which structure?"
"The one beneath the station, I assume."
"Your confidence is inspiring."
He glanced at me. "I’d rather admit what I don’t know than pretend I understand more than I do."
That was the first answer he’d given me in a while that I fully believed.
Nyelle suddenly stopped beside the stairs. "Do you hear that?"
I listened until a faint metallic rhythm emerged from below, repeating at regular intervals. Three knocks, a pause, then three more. My right hand warmed, and when I looked down, a silver line had appeared beneath my skin, extending from the center of my palm toward my fingers.
The stranger caught my wrist. "Don’t respond."
"I haven’t done anything."
"Your hand has."
I stepped backward, and the silver line dimmed. The knocking stopped with it, leaving Nyelle staring at my palm as though she’d just witnessed something she desperately wanted to understand.
"It’s listening to you," she whispered.
"Or reacting to me."
"Does that distinction make you feel better?"
"Not particularly."
The stranger checked his device again. SUBJECT 01: PROXIMITY CONFIRMED. ACCESS: DENIED. Beneath the message, another line appeared: SECONDARY RESPONSE: PRESENT.
Nyelle’s expression tightened. "That’s me."
"Probably," I said, but the stranger warned us against assuming that every message referred to a person. Before I could question him further, the knocking resumed, louder this time, and a low vibration travelled up through the metal railings.
Dust lifted from the stairs.
A pale blue light appeared beneath the entrance, revealing an ancient symbol carved into the station wall: three overlapping circles surrounding the narrow mark I’d seen on the monitoring device. My right hand burned, and the System appeared before my eyes.
[ANCIENT STRUCTURE DETECTED.]
[ACCESS CONDITION: INCOMPLETE.]
The display vanished.
Then Nyelle pulled out her cracked phone.
Its screen lit up, revealing a photograph of a white room, a machine, and a woman standing beside a table. I recognized our mother before the image sharpened enough to show her face, and the sight of her standing inside a room connected to the structure made my chest tighten.
Nyelle enlarged the photograph. A small child stood beside the machine, mostly hidden from view, but the next line of text made my stomach drop.
SUBJECT 01: INITIAL RESPONSE.
Another message followed.
SUBJECT 02: RESPONSE SUPPRESSED.
Nyelle’s hand began to shake. "That’s me."
The photograph changed, showing our mother holding a baby while a man in a white coat stood behind her. His face was obscured by a distortion, but the small metal ring in his hand was unmistakable: three overlapping circles engraved across its surface.
Then a final instruction appeared.
DO NOT ALLOW BOTH SUBJECTS TO ENTER.
The phone went black.
For several seconds, neither of us spoke. The photograph had answered one question while creating several worse ones: Nyelle had been involved in the experiment, our mother had known what was happening, and someone had anticipated the possibility that both subjects might eventually return.
I looked at Nyelle, who was staring at the dead screen with tears running down her cheeks.
"I’m sorry," I said.
"You didn’t do this."
"No, but I should have noticed something was wrong when you started remembering the symbols."
"You were trying to find me."
"And I found you." I held her gaze. "Whatever happened twenty-four years ago, we’re not going to let them decide what happens next."
She took my hand, and the silver line beneath my skin brightened. A faint warmth spread from her fingers into my palm, the two responses seeming to recognize each other, until the stranger ordered us to separate.
The light faded when Nyelle released me.
"The connection is changing," he said.
"Changing into what?" I asked.
"I don’t know."
At least he had stopped pretending uncertainty was a personal failure.
The device sounded again, displaying a single instruction.
SUBJECT 01: ENTER ALONE.
SUBJECT 02: REMAIN OUTSIDE.
Nyelle immediately shook her head. "No. We have spent the entire day following things that claim to know us, and every time we listen, someone gets hurt. I’m not staying outside while you walk into another place that might erase you."
"I don’t want you to stay outside."
"Then don’t go."
I looked down the stairs, where the metallic knocking had resumed. We could leave and search for another route, but the photograph had connected our past to this structure, and walking away wouldn’t make the mystery disappear.
The stranger offered another possibility: perhaps the condition referred to the order of entry rather than permanent separation. If I entered first, the structure might register me before responding to Nyelle, although he admitted it could just as easily trap me inside.
"That isn’t helpful," Nyelle said.
"No," he agreed. "But it’s the only interpretation I can support."
I studied the silver mark on my palm. The System had once told me that human civilization wasn’t included in the original design, and every ancient structure we encountered seemed to recognize something in me that I couldn’t remember.
Now the records suggested that I had been the first subject to awaken while Nyelle’s response had been suppressed.
Whatever waited below had been expecting us.
I squeezed Nyelle’s hand once before releasing it. "I won’t go far. If anything changes, leave immediately. Don’t wait for me."
Her eyes filled with anger. "You don’t get to make that decision for me."
"I know."
"Then stop acting like you do."
I had no answer.
I stepped onto the first stair, and the blue light brightened. As I descended, the knocking stopped, and a metal door slid open at the bottom, revealing a narrow corridor lined with black stone and shifting silver symbols.
Nyelle stood beside the stranger, watching me with an expression I knew I would remember for a long time. I stepped through the doorway, and the door began to close behind me.
The System appeared.
[SUBJECT 01: RECOGNIZED.]
[SUBJECT 02: RESPONSE SUPPRESSED.]
Then another message flickered across the display, its characters breaking apart as though something were trying to erase them.
ORIGINAL SUBJECT: STILL PRESENT.
The door slammed shut.
From somewhere deep within the corridor, a voice spoke in my mother’s tone.
"Veyric, you came back."
I stopped walking.
Because this time, the voice wasn’t asking me to open a door.
It was welcoming me home.
