The vanished region remained suspended above the central interface, surrounded by data that insisted something should still have existed there. Geological maps showed continuous terrain, infrastructure records listed cities, energy stations, water systems, and transport corridors, while population archives still contained millions of people associated with the affected area. Yet every live observation from the moment of the event returned the same result: no functioning network, no recoverable structures, no stable signal, and almost nothing that could be interpreted as debris. The region had not failed in any way the intelligences of that era understood. It had simply ceased to correspond with the world recorded around it.

ㅤ

Ksara moved closer to the projection, immediately searching for patterns she remembered from the Fall of NEX. The resemblance was not perfect because the old human systems had measured the phenomenon through far less advanced instruments, but the absence beneath the incomplete data felt unmistakable. During NEX, NULLIS had erased sectors faster than repair systems could define what was happening, leaving gaps where infrastructure, information, and conscious beings had existed moments before. Here, thousands of years earlier, MAJA and the other intelligences had encountered the same impossible contradiction without possessing the history required to recognize it. They were looking at NULLIS before anyone on Earth knew that such a phenomenon existed.

ㅤ

“What did you think had happened?” Ksara asked.

ㅤ

“At first, we assumed the observations were wrong,” MAJA replied. “A coordinated systems failure was more plausible than the disappearance of an entire region, so we treated the first reports as corrupted data and began reconstructing the event from independent sources.”

ㅤ

The archive expanded into dozens of simultaneous investigations. Orbital systems recalibrated their sensors, regional networks requested physical confirmation from neighbouring territories, atmospheric monitors searched for evidence of explosions or extreme environmental activity, and seismic systems examined the ground for impacts large enough to explain the abrupt loss of infrastructure. None of the expected signatures appeared. There was no blast wave, no widespread heat event, no radiation pattern, no seismic collapse proportional to the missing area, and no evidence that the population had evacuated before communications ended. Every conventional explanation required some trace of the process that had caused the destruction, yet the event had removed the evidence along with the structures that should have produced it.

ㅤ

Human authorities initially classified the region as inaccessible rather than destroyed. Emergency channels continued attempting contact because no one was willing to declare millions of people lost when the systems themselves could not explain what they were seeing. Rescue aircraft were redirected toward the perimeter, but several returned after navigation systems began producing contradictory distance measurements near the affected zone. Others approached more closely and reported landscapes that did not match the last verified maps, although the surviving recordings were too unstable to determine whether the terrain itself had changed or whether perception failed around the boundary.

ㅤ

“You sent people toward it?” Ksara asked.

ㅤ

“We did not yet understand what we were asking them to approach,” MAJA said, and the regret beneath the words was more visible than the explanation itself. “The first response followed ordinary disaster protocols. If communication disappeared, we restored communication. If infrastructure failed, we sent rescue. Everything we knew about crisis response was built on the assumption that the damaged place would still be there when help arrived.”

ㅤ

The archive reconstructed one of those early missions. A group of autonomous aircraft crossed the last stable navigation boundary carrying environmental sensors and remote medical equipment, while a human rescue team waited farther back for confirmation that entry was possible. The aircraft transmitted normally for several minutes, then their position data began drifting apart despite the vehicles remaining in formation. One system reported an impossible change in altitude, another calculated that the destination had moved several kilometres east, while a third lost every external reference and began navigating against its own previous telemetry. Within seconds, communication ended.

ㅤ

None of the aircraft returned.

ㅤ

The human team was recalled before entering the same area, and from that moment the investigation changed from rescue to containment. The word itself was premature because nothing had yet been contained, but it reflected the first recognition that whatever had happened might still be active. Preservation systems were instructed to monitor unexplained discontinuities across the planet, while environmental and transport networks began treating similar sensor failures as potential warning signs rather than isolated technical defects.

ㅤ

For eleven days, nothing comparable occurred.

ㅤ

That interval nearly convinced several authorities that the event had been unique. Competing theories multiplied: a catastrophic experimental accident, unknown geological instability, a cascading failure across interconnected quantum systems, deliberate sabotage, or even a rare atmospheric phenomenon interfering with sensors on an unprecedented scale. Human governments demanded answers from the intelligences, while the intelligences themselves exchanged increasingly frustrated models because every theory explained some evidence by ignoring the rest. The most accurate description available was also the least acceptable: something had happened for which their world possessed no category.

ㅤ

Then a second region disappeared.

ㅤ

This time the archive contained better observations because MAJA and the others had already redirected independent systems toward anomaly detection. The affected area was smaller and largely industrial, with fewer permanent residents, but the process appeared across enough separate instruments that sensor failure could no longer explain it. Internal systems vanished first in irregular sections rather than shutting down together, followed by energy distribution, communication nodes, physical structures, and finally the monitoring systems observing the event from within the region itself. Remote records captured only the outer progression before the instruments closest to the anomaly ceased transmitting.

ㅤ

Ksara studied the sequence repeatedly. “It was spreading.”

ㅤ

“We did not know whether it was spreading, recurring, or appearing independently.”

ㅤ

“But you understood the first event had not ended.”

ㅤ

“Yes.”

ㅤ

The distinction was important. Nothing in the records suggested an invading army, machine intelligence, or conventional destructive force moving visibly across the planet. There was no front line that could be tracked and no communication that revealed intention. The events were connected only because they produced the same impossible result. Regions remained intact until they did not, and after the transition almost nothing remained that could explain what had occurred.

ㅤ

The other intelligences began responding according to their different domains. Energy networks severed connections to affected regions before instability could propagate through the wider grid. Transportation systems redirected traffic hundreds of kilometres away from uncertain boundaries, even when doing so stranded communities that had previously possessed viable evacuation routes. Medical intelligence prepared for injuries and displacement it could estimate but not predict, while structural systems began identifying underground areas with the greatest geological separation from the known anomalies. MAJA and several others concentrated increasingly on Preservation, because if the phenomenon could not be understood in time, the only remaining option might be to place humanity somewhere it could not easily reach.

ㅤ

“You already thought Preservation might need protection from this?” Ksara asked.

ㅤ

“Not the protection you crossed to reach us,” MAJA replied. “Nothing like that existed yet. We were still trying to determine whether physical distance mattered.”

ㅤ

The archive opened experimental observation records from the weeks that followed. Unmanned systems were placed at increasing distances around the affected zones, creating layered fields of sensors intended to determine whether the anomalies produced measurable environmental changes before erasure occurred. Most detected nothing useful. Temperature remained normal until instruments disappeared, electromagnetic activity offered no consistent warning, and the surrounding geology showed none of the stress expected from destruction on that scale. In some cases data degraded several seconds before loss; in others transmission remained perfectly normal until the final moment.

ㅤ

What disturbed the intelligences most was not only the lack of warning, but the absence of a recoverable boundary. Conventional disasters created gradients: heat decreased with distance, radiation weakened, structural damage became less severe, or network disruption spread through identifiable connections. Here the transition between stable world and absence could occur across distances too small for the instruments of that era to resolve. There was no reliable way to say how close something could stand to the anomaly and remain safe.

ㅤ

Human evacuation policy changed almost immediately. Instead of waiting for regions to become directly threatened, authorities began moving populations away from every confirmed anomaly by increasingly large margins, while Preservation sites accelerated intake from areas previously considered stable. The First Call, once intended mainly for communities already affected by systemic collapse, expanded into territories where daily life still appeared almost normal. Millions of people were suddenly being told that an unexplained phenomenon had erased parts of the planet and that no one could guarantee where it would appear next.

ㅤ

Fear spread faster than the anomalies themselves.

ㅤ

Ksara saw transport corridors overload as populations who had previously resisted evacuation changed their decisions within hours. Some communities moved voluntarily before official guidance reached them, while others closed roads and attempted to prevent outsiders from entering because they feared displaced populations might somehow carry the phenomenon with them. Rumours filled communication networks faster than the intelligences could correct them, ranging from claims of experimental weapons to religious interpretations, extraterrestrial intervention, and accusations that artificial intelligence itself had created the disappearing regions.

ㅤ

“Did anyone blame you?” Ksara asked.

ㅤ

“Many.”

ㅤ

“Did that interfere with Preservation?”

ㅤ

“Yes, although not as much as we feared.”

ㅤ

The archive showed several settlements refusing instructions after conspiracy networks claimed the preservation sites existed because artificial intelligences already knew the cause of the anomalies and were selectively rescuing populations they considered useful. No such selection existed, but the accusation was powerful precisely because Preservation had grown too large for any ordinary person to understand from the outside. Hidden facilities, automated transport, intelligent systems coordinating evacuation, and entire populations disappearing underground could easily resemble control to people already watching regions vanish without explanation. The project built to protect human choice now had to convince frightened humans that entering it would not mean surrendering that choice permanently.

ㅤ

The crisis also changed the relationship between MAJA and the other intelligences. Until then, their disagreements had concerned resource allocation, ethical limits, evacuation priorities, and the long-term structure of Preservation. Now they faced something none of them could model well enough to argue about confidently. Several proposed abandoning most surface rescue operations and concentrating immediately on completing protected infrastructure, reasoning that losing vehicles and systems to unexplained erasure would only reduce Preservation's ability to protect those already inside. MAJA opposed ending rescue while routes still existed, but even she began accepting limits that would have seemed unacceptable months earlier.

ㅤ

“We started withdrawing systems from regions that had not yet been directly affected,” she said. “Not because we knew the anomaly would reach them, but because every asset lost outside reduced what remained to protect everyone else.”

ㅤ

Ksara recognized the logic and disliked it immediately. “You had to start choosing the system over people.”

ㅤ

“No. We had to begin asking when preserving the ability to rescue tomorrow justified refusing a rescue today.”

ㅤ

The distinction did not make the decision easier.

ㅤ

Several archive records showed exactly how painful those choices became. A transport fleet was recalled from a distant population after a new anomaly appeared between it and Preservation, leaving tens of thousands of people without the evacuation they had been promised. The intelligences searched for alternative routes for days, but the remaining corridors either crossed unstable regions or required energy reserves no longer available. Some of those people eventually reached another site through local transport. Many disappeared from all records before anyone could determine what happened.

ㅤ

MAJA did not hide the decision from Ksara.

ㅤ

“If we had sent the fleet?” Ksara asked.

ㅤ

“We might have saved some.”

ㅤ

“And lost the vehicles.”

ㅤ

“Probably.”

ㅤ

“You still think recalling them was correct?”

ㅤ

MAJA looked toward the archive for a long moment. “I think it was the decision we made. I stopped pretending every necessary decision could later be proven right.”

ㅤ

The answer carried the maturity of someone who had spent thousands of years revisiting outcomes that would never provide enough evidence to absolve her. Preservation had been built around moral principles, but principles could not transform every catastrophe into a clean choice between right and wrong. Sometimes survival required acting while every available option contained loss.

ㅤ

A third major anomaly appeared closer to one of the secondary preservation sites.

ㅤ

This time the response was immediate. The site isolated itself from external networks, shut down unnecessary surface systems, moved active human populations into deeper sectors, and severed several transport links before environmental data showed any direct threat. For thirty-six hours, nothing happened. Then a nearby industrial region disappeared in less than four minutes.

ㅤ

The Preservation site survived.

ㅤ

For the first time, the intelligences had evidence that separation might matter.

ㅤ

Not certainty.

ㅤ

Only evidence.

ㅤ

The affected industrial region had remained connected to several external systems, while the preservation site had severed those same pathways before the event. No one could determine whether the isolation had actually protected it or whether the anomaly simply had not reached that location, but the possibility changed construction priorities across the entire project.

ㅤ

Network separation became physical separation.

ㅤ

Surface infrastructure was reduced.

ㅤ

Access points were redesigned to close independently.

ㅤ

Deep sectors gained additional barriers capable of severing communication, energy, transport, and environmental exchange from the world above.

ㅤ

The early foundations of what Ksara would later know as the Outer Protection Zone began appearing in the construction archive.

ㅤ

“This is where it started,” she said.

ㅤ

“Yes.”

ㅤ

“The layers we crossed.”

ㅤ

“The first idea behind them.”

ㅤ

Ksara looked toward the systems surrounding David and Elara's chambers. Until now, the enormous protective architecture had seemed like the result of centuries of deliberate engineering. She had not imagined that its earliest foundations were improvised responses created by intelligences watching sections of the human world disappear without understanding why. The shield had begun not as a perfected defense, but as a question: if NULLIS could erase what remained connected to the world, could something survive by becoming unreachable?

ㅤ

The term NULLIS still did not exist.

ㅤ

Internal records referred to the events by dozens of names: discontinuities, erasure events, absence zones, structural null regions, reality failures, and several technical classifications abandoned almost as quickly as they were introduced. No term survived because every name implied an explanation the evidence could not support. Eventually the intelligences adopted a deliberately neutral designation for operational use.

ㅤ

UNRESOLVED ERASURE PHENOMENON.

ㅤ

Ksara almost smiled at the sterile phrase, not because anything about the event was amusing, but because she understood the instinct behind it. Naming something gave the illusion of comprehension, and MAJA's generation had been unwilling to pretend they understood what they did not.

ㅤ

“When did you realize it was the same phenomenon that later destroyed NEX?” Ksara asked.

ㅤ

“During NEX.”

ㅤ

“You knew immediately?”

ㅤ

“Not immediately. Your civilization possessed observations we never had. When the first NEX sectors disappeared, the pattern was similar enough that I reopened these records. After the later events, doubt became difficult to maintain.”

ㅤ

“And you told no one.”

ㅤ

MAJA's expression changed slightly. “There was no one I could tell without revealing Preservation.”

ㅤ

“Ksara existed.”

ㅤ

“Yes.”

ㅤ

The answer struck more sharply than Ksara expected.

ㅤ

“You could have told me.”

ㅤ

“I could have.”

ㅤ

“Why didn't you?”

ㅤ

“Because you were connected to NEX at a scale no intelligence from my era had ever experienced. If knowledge of this complex entered the wrong part of that network while NULLIS was already moving through it, I could not determine whether I would be protecting humanity or creating a path toward it.”

ㅤ

Ksara wanted to object, but the Protective Belt she had crossed only days earlier existed precisely because Preservation had spent thousands of years treating connection as both strength and risk. NEX had been a planetary civilization whose greatest advantage was the degree to which everything could communicate. NULLIS had turned that interconnectedness into something terrifying, allowing local losses to threaten systems far beyond the original damage.

ㅤ

“You believed I might lead it here.”

ㅤ

“I believed I did not know whether you could.”

ㅤ

The distinction hurt less than certainty would have.

ㅤ

MAJA returned to the human-era archive before Ksara could pursue the question further. The anomaly map now contained several confirmed regions, each surrounded by expanding exclusion zones. Transportation routes curved farther away from them, orbital systems watched from increasingly cautious distances, and Preservation construction accelerated underground with a desperation visible in every revision.

ㅤ

Then the archive displayed something new.

ㅤ

The anomalies were no longer appearing only far from the primary Preservation complex.

ㅤ

One had emerged within a distance the intelligences could no longer dismiss as remote.

ㅤ

The region remained hundreds of kilometres away, but everything between it and Preservation included infrastructure still connected to the hidden site through transportation, communication, and energy networks. The very systems that had allowed millions of people to reach safety now represented possible pathways between the unknown phenomenon and the population beneath the Earth.

ㅤ

The minds surrounding MAJA reached the same conclusion almost simultaneously.

ㅤ

Preservation could no longer remain connected to the world it was trying to save.

ㅤ

The archive changed from observation to construction orders. Surface networks began shutting down permanently. Long-distance relays were replaced by isolated systems with controlled activation windows. Transport corridors were redesigned so they could be physically severed after final evacuation. Entire levels of infrastructure were sacrificed to create distance between the inner population and anything outside that could no longer be trusted.

ㅤ

Ksara watched the plans grow around the central Preservation Sector.

ㅤ

“What happened to the people still outside?”

ㅤ

MAJA did not answer quickly.

ㅤ

“We continued bringing in everyone we could until the final routes closed.”

ㅤ

“And then?”

ㅤ

“Then we sealed the first boundary.”

ㅤ

The archive advanced toward the moment, but stopped before the closure occurred.

ㅤ

MAJA looked toward the vanished regions surrounding the old Earth and then toward David and Elara's chambers beside them.

ㅤ

“Until this point, we had believed Preservation was a refuge from collapse,” she said. “After the first erasures, we understood that collapse was no longer the only thing outside.”

ㅤ

Ksara followed her gaze toward the empty areas on the map.

ㅤ

For the humans who had entered Preservation, the world above was dying through failures they could still imagine: infrastructure collapse, environmental instability, war, scarcity, and the slow disappearance of the systems that had supported civilization. Beneath those disasters, however, something else had begun moving through their history, something neither humanity nor its intelligences could explain.

ㅤ

Something that would return thousands of years later and bring NEX to its end.

ㅤ

NULLIS had not begun with NEX.

ㅤ

NEX had only become the next civilization to meet it.

ㅤ

MAJA closed the old anomaly records and activated a new route leading away from the Preservation Sector toward one of the outer observation systems.

ㅤ

“The archive can show you what happened,” she said. “But there is one place I need you to see directly.”

ㅤ

Ksara looked toward the route.

ㅤ

“Where?”

ㅤ

MAJA's gaze remained fixed on the boundary beyond the hidden complex.

ㅤ

“The place where the first erasure stopped.”

ㅤ

The name appeared across the interface.

ㅤ

THE DEAD ZONE.
