Marcus did not lower his weapon, but his attention shifted.
The figure ahead was no longer the immediate threat.
The wall behind them moved again.
This time, it did not hesitate.
The surface distorted outward in a sudden, violent motion, as though something beneath it had lunged forward without needing to cross space. The concrete stretched without cracking, bending toward them in a way that made the air feel unstable.
Maya saw it first.
"It is not separate," Maya said, her voice tightening. "It is the corridor."
Elias turned sharply, but he reacted a fraction too late.
The wall snapped toward him.
Not like a strike.
Like a correction.
Marcus moved instantly. He grabbed Elias by the shoulder and pulled him forward just as the space behind him collapsed inward. The wall did not hit where Elias had been standing. It simply replaced it.
Elias stumbled hard into Marcus, struggling to regain his balance.
"That was not a near miss," Elias said, breath uneven. "That was removal."
"I know," Marcus said.
The wall receded again.
Not completely.
Just enough to pretend nothing had happened.
Ahead of them, the figures shifted.
One stepped forward.
Another adjusted to the side.
The third remained still, watching.
"They are coordinating with it," Maya said.
Elias shook his head. "That implies communication."
"They do not need communication," Maya replied. "They are the same system."
The floor shifted beneath them.
It was subtle, but enough.
Elias felt it first and dropped to one knee as the distance beneath him stretched just enough to throw off his footing.
Marcus reached down immediately and pulled him back up.
"Stay up," Marcus said.
"I am trying," Elias said, forcing himself upright.
The wall surged again.
Faster this time.
It pushed forward in jagged, uneven segments, like layers of space collapsing into alignment.
Marcus reacted on instinct.
He fired.
The shot struck the wall, and for a brief moment the surface recoiled, as though the impact had disrupted whatever held it together.
Maya saw it clearly. "You disrupted it," Maya said.
"For a second," Marcus replied.
"That is enough," Maya said.
The figures advanced.
Not together.
One lunged low.
Another moved from the side.
The third remained still—
But the space around it shifted, tightening the corridor and forcing movement.
Marcus stepped forward hard, pushing through the narrowing gap before it could close completely.
"Move," Marcus said.
Maya followed immediately.
Elias hesitated for a fraction of a second—
And that was enough.
One of the figures reached for him.
Not striking.
Grabbing.
Its arm extended unnaturally, stretching beyond normal length as it tried to close the distance.
Elias froze.
Maya reacted.
She swung the scanner in her hand and struck the figure's arm.
The contact distorted it instantly. The limb collapsed inward like dense liquid under pressure before snapping back into place.
Elias staggered backward, pulling away.
"I did not like that," Elias said.
"Then keep moving," Marcus replied.
They pushed forward again.
The corridor resisted.
The walls shifted.
The floor stretched and compressed beneath them in uneven intervals.
Elias nearly lost his footing again but caught himself this time.
"I am starting to understand why people do not come back from here," Elias said.
"Focus," Maya said.
The scraping sound returned.
Louder now.
Closer.
It came from everywhere at once.
The walls.
The floor.
The ceiling.
Marcus turned slightly, tracking the sound—
And saw the surface shift again.
Not outward this time.
Inward.
The corridor compressed.
Maya felt it immediately. "It is closing space," Maya said.
Elias looked around, panic creeping into his voice. "We are being compressed," Elias said.
Marcus stepped forward again, faster now.
"Then we move before it finishes," Marcus said.
Ahead, the figures spread wider.
Not blocking the path.
Shaping it.
Creating a narrowing corridor between them.
"They are funneling us," Elias said.
"They are deciding where we are allowed to exist," Maya corrected.
Marcus did not argue.
The wall surged again.
This time from the side.
Marcus saw it and shoved Maya forward just before the surface collapsed into the space she had occupied.
Maya stumbled, caught herself, and turned sharply. "That was too close," Maya said.
Marcus did not respond.
The corridor shifted again.
Everything at once.
Distance snapped.
The figures adjusted.
The walls pressed inward.
The floor stretched.
Elias lost his balance completely this time and fell hard.
Marcus grabbed him again and pulled him upright before the space behind him collapsed inward a second later.
Elias's breathing was uneven now. "We are not surviving this by accident," Elias said.
"No," Marcus said. "We are not."
The scraping sound stopped.
Suddenly.
Completely.
The silence that followed felt heavier than the noise had been.
Maya's voice dropped. "That is not a good sign," Maya said.
Marcus nodded slightly. "No," Marcus said.
The lights flickered.
Then dimmed.
For just long enough—
That something moved along the wall.
Not outward.
Not toward them.
But alongside them.
Keeping pace.
Watching.
Marcus steadied himself and looked forward again.
"We move now," Marcus said.
