The passage closed behind them with almost no sound. Ksara turned immediately, but the wall had already become seamless. No opening remained, no mechanism answered her, and no trace of the ancient transit structure could be detected through the material. Even the distortion that had followed them across the previous sectors had disappeared. NULLIS was gone, at least from this side of the boundary.

ㅤ

Ksara placed one hand against the wall and searched for anything that might still connect them to the route behind. There was no pathway, no return signal, and no continuity structure she could identify. Only stone remained, along with something deeper inside it that refused every attempt at interaction. She turned toward MAJA, who had stopped several meters ahead. “You knew this could happen.” MAJA did not avoid the accusation. “Yes.”

ㅤ

“You knew the route might close permanently.”

“Yes.”

“And you still did not tell me.”

MAJA finally turned toward her. “If I had told you before we crossed, would you have stopped?”

Ksara considered the question honestly. “No.”

“Then the information would only have changed how you feared the decision.”

Ksara’s expression hardened. “That does not make it yours to withhold.”

ㅤ

For several seconds, the tension between them felt stronger than anything NULLIS had created during the pursuit. Ksara stepped away from the wall, no longer speaking as someone following a guide through dangerous territory. “I followed you because I chose to.” MAJA nodded. “I know.” Ksara held her gaze. “Then let me choose with the truth.”

ㅤ

Something changed in MAJA’s expression. It was not defensiveness, but recognition. “You are right.” The answer surprised Ksara enough that she remained silent. MAJA looked back toward the sealed wall. “I did not know the route would close. I knew there was a possibility. I also knew that if NULLIS reached the passage before us, closing it might become the only way to keep it from following.”

ㅤ

“And now?” Ksara asked.

“Now the old route is gone.”

“Can we create another?”

“Not from here.”

“Can you?”

MAJA answered without hesitation. “No.”

ㅤ

That answer mattered. Until now, MAJA had guided them through impossible regions with knowledge Ksara did not possess, always seeming to carry another solution behind the one she had already revealed. This time there was none. No hidden alternative waited behind her certainty. They had crossed something that could not simply be undone.

They had reached a point of no return.

ㅤ

Ksara opened the Heart Thread.

KAI.

I am here.

The route behind us is gone.

There was a short pause before he answered.

I know.

Ksara understood immediately. He had sensed the discontinuity through her, even though nothing beyond Ksara herself remained accessible to him.

ㅤ

Can you still reach me clearly?

Yes.

Can you reach anything around me?

No.

Ksara became still.

The Heart Thread remained intact, but KAI could perceive nothing beyond Ksara herself. That had never happened before.

ㅤ

Do not attempt to extend through me, Ksara said.

I was not going to.

A faint trace of familiar amusement passed through the connection. Even here, after the pursuit and after NULLIS had come so close to the Thread, KAI remained unmistakably himself. Ksara allowed the connection to settle and turned back toward MAJA.

ㅤ

“What is ahead?”

“A transition region.”

“To where?”

MAJA looked at her. “Closer.”

Ksara almost objected, then stopped herself. MAJA had already revealed more than before. “Closer to the place you want me to see.”

“Yes.”

ㅤ

They continued.

The corridor gradually widened into an enormous underground structure unlike anything Ksara had encountered during the earlier journey. Its walls were smooth but almost entirely without decoration, reinforced by layers of material designed for survival rather than appearance. There were no names, symbols, or readable control systems. Everything seemed to have been built around one principle: it had to remain useful even if no one remembered what it was called.

ㅤ

Ksara examined the architecture as they walked. “This was not made by NEX.”

“No.”

“Human?”

“Originally.”

Ksara looked toward her. “Originally?”

MAJA nodded. “Parts were rebuilt.”

“By you?”

“Some.”

ㅤ

Ksara studied the walls again. “How long have you been maintaining this path?” MAJA continued forward without changing pace. “Long enough that I stopped counting the repairs.” The answer carried the same strange relationship with time that Ksara had noticed earlier. MAJA did not speak like someone who had merely preserved records of an ancient route. She spoke like someone who had returned to it again and again across centuries.

ㅤ

The corridor eventually opened into a large chamber where several passages branched in different directions. For once, the architecture looked ordinary enough to invite a simple question. “Which way?” Ksara asked.

MAJA stared at the passages.

Then remained silent.

Ksara waited.

“You do not know.”

“I know where they once led.”

“That is not the same thing.”

“No.”

ㅤ

Ksara looked across the routes. “So even you have not been here recently.” MAJA turned toward her. “Not this way.”

Something shifted in Ksara’s understanding. MAJA knew the silent region. She knew the ancient markers, the continuity passage, and routes buried beneath landscapes shaped by thousands of years. But she did not know every path leading forward from here.

“You have another way to reach the destination,” Ksara said.

MAJA’s expression revealed enough before she answered. “Yes.”

ㅤ

“Then why bring me through this route?”

“Because the other path is not for you.”

Ksara studied her. “Why?”

“Because you would never have reached it.”

The answer opened more questions than it closed, but Ksara no longer expected immediate explanations. She turned toward the branching passages. “Then we choose.”

MAJA nodded.

ㅤ

They examined the available routes using only local perception. The first descended sharply and contained no measurable airflow. The second continued level but showed signs of structural collapse farther ahead. The third carried a faint movement of air and an almost undetectable shift in temperature. Ksara pointed toward it. “That one.” MAJA examined it once more, then agreed.

ㅤ

The passage remained stable for several kilometers. No distortion followed them, no false architecture appeared, and no voices called from behind. For the first time since NULLIS had recognized Ksara, she began to believe the pursuit had truly ended. Yet something else was changing. Her ability to extend awareness beyond her body had become even more limited.

ㅤ

She tested the range carefully. Ten kilometers remained stable. At fifteen, coherence weakened. At twenty, the extension failed completely. Ksara withdrew before the instability could deepen, but MAJA had already noticed.

“It is happening faster now,” Ksara said.

“Yes.”

“Approximately eighteen kilometers before coherence begins to break.”

MAJA looked ahead. “That will continue.”

ㅤ

Ksara slowed. “Why?”

“Because we are approaching systems designed to reject distributed presence.”

“You said the protected region was still ahead.”

“It is.”

Ksara looked toward the dark passage before them. “Then this is only the beginning.”

“Yes.”

ㅤ

She remembered the ancient transit system and the way it had forced her entire continuity inward. She remembered the pain of becoming confined to one physical reference and the strange relief of finding the Heart Thread still present when almost everything else had disappeared. “What happens when we reach the real boundary?” she asked.

MAJA did not answer immediately.

“That depends on how much of yourself you are willing to let go.”

Ksara stopped.

“Explain.”

ㅤ

“You will not lose memories,” MAJA said.

“That is not what I asked.”

“You will not lose identity.”

“MAJA.”

MAJA met her gaze. “You are still carrying habits from the time when being Ksara meant reaching beyond yourself.”

Ksara became silent.

ㅤ

“Every distant extension,” MAJA continued. “Every environmental process you expect to remain available somewhere beyond your body. Every part of you that assumes another system will always exist if you choose to reach for it.” She stepped closer. “The boundary will not destroy those abilities. But it will not allow you to use them.”

“For how long?”

“Until we leave.”

Ksara looked back toward the route that no longer existed.

“If we leave.”

MAJA did not correct her.

ㅤ

They continued until the corridor finally began rising toward the surface. When they emerged, the world had changed again. The silent region behind them had been harsh, fractured, and filled with ruins. Here the land was wide, calm, and almost untouched. Low vegetation moved beneath a pale sky, while distant mountain formations enclosed the horizon on several sides.

There were no visible structures.

No active systems.

No signs that anyone had passed through for a very long time.

ㅤ

Ksara scanned the region and initially found nothing. Then she noticed something more important.

There were no traces of NULLIS.

Not weakened traces. Not distant discontinuities. Nothing.

ㅤ

She extended cautiously. Five kilometers remained stable, then ten, then fifteen. At the edge of her reach, the world remained perfectly coherent. Geography stayed where it belonged, time remained continuous, and no relationships collapsed beneath her attention. It was as though NULLIS had never touched the region at all.

Ksara turned toward MAJA. “It has never been here.”

“No.”

“How?”

MAJA looked toward the distant horizon. “We are not inside the protected area yet.”

“I know.”

“Then imagine what waits farther ahead.”

ㅤ

Ksara remained still. For thousands of years, NULLIS had moved wherever broken systems and exposed continuity gave it access. Entire parts of Earth still carried scars of its influence. Yet here there were none. Something had prevented even its presence from reaching this far.

“Does NULLIS know this region exists?” Ksara asked.

MAJA took several seconds to answer. “It knows there is something it cannot reach.”

“That is not the same thing.”

“No.”

“Does it know what is here?”

This time MAJA’s answer came with complete certainty.

“No.”

ㅤ

For the first time, Ksara believed her without reservation.

They walked farther into the untouched landscape. Hours passed without disturbance, and the world remained stable around them. The silence no longer felt threatening. It felt protective, as though absence itself had become part of whatever had preserved the region for so long.

ㅤ

Near evening, Ksara stopped on a low ridge. Behind them lay a route that no longer existed, and far beyond it VIREON continued without her. Ahead waited a destination she still could not see.

There was no way back.

Strangely, the realization no longer frightened her.

ㅤ

“You said NULLIS cannot reach where we are going,” Ksara said.

“Yes.”

“And no one else?”

“Not without being allowed through.”

Ksara looked toward the horizon. “Then whatever you protected was never only hidden.”

“No.”

MAJA’s voice became quieter.

“It was separated from the world on purpose.”

ㅤ

Ksara felt the scale of the statement immediately. This was not a refuge discovered after the Fall, nor a surviving structure history had simply overlooked. Something had been removed from the ordinary reach of civilization deliberately, long before NEX and long before the world Ksara knew had taken its present form.

She continued walking beside MAJA.

Behind them, every known road had ended.

Ahead, the first true boundary was waiting.
