Chapter 62 — Water Before Walls
The island did not feel hunted anymore; it felt fragile. And fragility begins with water.
Lufias stood at the eastern stream before sunrise. Mist hovered low above the surface, clinging to roots and stones like a cold, damp shroud. The current was steady, slipping between rocks in a quiet, persistent rhythm. It looked clean.
In the Delta, looking clean meant nothing.
Lyra joined him, her arms folded tightly against the morning chill. Her eyes were red-rimmed from the lack of sleep. We start clearing the perimeter today? she asked.
No, Lufias replied.
She frowned, her gaze shifting to the dense underbrush where the silhouettes usually gathered. Then what?
Water.
She stared at him, her expression a mix of exhaustion and disbelief. Walls can wait, he continued quietly. Water cannot.
Revas approached from behind, his boots crunching on the dry leaves. We have got limited manpower, Lufias. Why water first?
Lufias did not answer immediately. He crouched beside the stream and picked up a flat stone. He turned it over. The underside was clean. No algae bloom. No slime. He let it fall back into the current with a sharp splash.
Tomas was not taken, he said.
Lyra's jaw tightened.
He was infected.
The silence that followed was heavy. Revas looked at the water, then back at Lufias. From the river?
Yes.
No bite?
No.
No wound?
No.
Lyra exhaled slowly, the realization settling in her eyes. He was on river watch three nights straight. He complained about thirst.
And he stopped boiling his water, Lufias finished.
That was the truth no one wanted to say. Aeris stepped closer, her voice a clinical whisper. The virus lives in the water. Not the air. Not the soil.
Water.
Lufias nodded once. It does not spread through breath. It spreads through intake.
Revas looked at the stream again, his hand hovering over his canteen. So this is the priority.
Yes. If we build walls first, then someone drinks the wrong water, Lufias said. And we bury another body.
The Site
The stream curved along the eastern side of the island before merging into the larger river downstream. The source was inland, fed by a shallow spring between layered stone. No settlement upstream. No visible corpses. No stagnation.
But visible meant nothing. Water flows, Lufias said, drawing lines in the wet soil with a stick. Virus drifts. If infected bodies decompose upstream, particles travel. We do not drink the direct flow. We redirect.
He marked a basin site three meters from the stream's main channel, positioned at an elevation slightly higher than the river merge to prevent backflow during floods.
Length: two meters. Width: one and a half. Depth: half meter.
Why not deeper? Lyra asked.
Deeper collapses easier in this soil. Angle the walls. Forty-five degrees. Vertical walls collapse under saturation; sloped walls distribute the pressure.
Day 1 — Digging
The first hour was defined by silence and impact. Metal scraped soil. Roots tore. Breath became heavy and rhythmic. The basin formed slowly, mud clinging to boots and hands blistering under the friction of the shovels.
They lined the bottom with fist-sized gravel collected from the riverbed. Gravel first, Lufias said. Allows the water to spread evenly.
Then came the charcoal—burned wood crushed into coarse, black fragments.
Charcoal binds toxins, Aeris murmured.
Some, Lufias corrected. Not all. Still boil.
Sand was layered on top. Fine river sand, rinsed meticulously to remove surface debris. They stretched a salvaged tarp along the outer slope to stabilize the soil, then built a narrow diversion channel from the stream using stacked stone and packed mud.
A controlled trickle entered the basin. Slow flow, Lufias noted. It increases the contact time with the filtration layers.
By dusk, the sediment had settled. Clarity improved.
Drain it, Lufias said.
Arlen frowned. Already?
First fill carries construction debris.
They opened a side trench and watched the gray water drain back into the stream. The second fill began. Clearer. Still not trusted. Aeris boiled water from both the basin and the main stream, comparing the scent and clarity.
Similar, she said.
That does not mean safe, Lufias replied.
He took a small sip of the boiled basin water. He held it in his mouth, then swallowed. Everyone watched him. He waited. Nothing happened. The virus did not attack instantly; it was a slow, calculated takeover.
Still boil, he repeated. Always boil.
The Reminder
The walker came at dusk. It was mud-caked and unstable, drifting from the northern brush toward the stream. It did not move toward the camp; it moved toward the water.
The infected gravitated toward moisture. Whether it was a biological instinct or a viral response, the result was the same. Nera spotted it first.
North.
Lufias walked toward it. The walker stepped into the stream, the water rippling around its decaying legs.
One shot. It fell face-first into the current.
Time seemed to slow. Blood thinned into red threads, twisting downstream. Lufias moved instantly, wading into the current without hesitation. He grabbed the corpse by its tattered collar and dragged it onto the bank before the contamination could spread.
Burn it, he said. No bodies near the water.
The smoke rose thick and black against the twilight. The lesson stayed with them long after the fire died down. One corpse. One moment. The system was that easily compromised.
The Shift
By the end of the first week, the basin was stable. The water was filtered and boiled before every use. Fish traps were placed downstream, and a buffer zone was cleared thirty meters outward from the camp.
Lufias drew the zones in the dirt. Zone 1 for living. Zone 2 for work. Zone 3 was a cleared buffer. Zone 4 was the kill zone. They hung scrap metal lines between trees at ankle height to act as noise detectors.
If anything crosses Zone 3, we hunt immediately, Lufias said. No observing. No waiting. Stress feeds the infection.
The Watchers had circled to reduce sleep and raise heart rates. They had weakened the survivors' immune systems. Tomas had been tired and dehydrated. The virus did not need bites; it needed opportunity.
That night, Kaelyn sat by the fire. It feels different, she said. Like we are not running.
Lufias stood beside the basin. He dipped his hand into the clear surface. The water was cold and clean. Earned. But he knew how fragile it was. He looked at the flowing stream beyond their small filter.
Water first, he murmured.
Revas stood beside him. You think this is enough?
No. But it is necessary.
Lufias flexed his shoulder. It held. For now. The island was not safe. Rain would come, floods would rise, and upstream bodies would eventually drift into their reach. But they had control over their intake.
And control over intake meant control over the infection. Walls could wait. Survival began long before the enemy reached the perimeter.
