Chapter 26 — The Calculus of Attachment
Reality: 2066
The first thing Lufias felt was warmth. The second was its clinical absence.
He opened his eyes to a white ceiling. Sterile. Perfect. The morning light was filtered through high-grade UV-tinted glass, and the air was still, scrubbed clean by the apartment's life-support system.
For several seconds, he didn't move. The memory of the Delta lingered—not as a visual, but as a lingering sensation. He could still feel the phantom rhythm of the boat against his ear and the subtle, grounding rise and fall of Nera's breathing.
He sat up slowly, pressing a palm against his sternum. His heartbeat was steady now, but he remembered how it had faltered last night. Not from fear, but from something far more unpredictable.
"That's dangerous," he whispered to the empty room.
In his world of equations and tactical simulations, attachment was a "Noise Variable." It complicated risk assessment. It made a leader hesitate when a sacrifice was required. But as he stood before the mirror, looking at the tired seventeen-year-old staring back, he realized the equation had flipped.
Attachment was a risk, yes. But it was also a stabilizer. He wasn't just surviving for a "Self" anymore; he was surviving for a "Unit." And a unit with a heart was harder to break than a machine with a directive.
The Nautical Study
He washed his face with ice-cold water, resetting his focus. He opened his laptop, the blue light reflecting in his dark pupils. This time, he didn't search for "Ballistics" or "Fortification."
Search: Small engine maintenance; Hydrodynamic drift; River compression points.
He watched videos on how to clear a clogged fuel line with nothing but a wire and a prayer. He studied how current accelerates when a river narrows—the "Venturi Effect"—and how debris collects in the center of a constricted channel.
He wrote in his notebook: Never take the center channel in a narrowing flow. The velocity is highest, but the debris-density is lethal.
He closed the laptop. Nera's voice echoed in his head: "Depend on me a little." Leadership didn't mean carrying the mountain alone; it meant making sure the mountain didn't crush the people behind you. He went for a measured run, letting his breathing settle into a rhythmic, 2066-standard pace. When he returned, he lay down without hesitation.
The ceiling blurred. The darkness folded.
The Delta — Southbound
Cold air. The smell of river moss. The low, rhythmic shift of water against fiberglass.
Lufias sat upright in the bow, his rifle resting in the crook of his arm. The morning light was a pale, sickly yellow, stretching across the mist-covered water.
Kaelyn stood at the stern, guiding them with a long, scavenged pole along the shallower edge of the bank. Aeris was a statue at the midsection, her eyes locked on the Northern treeline. Nera was still asleep, her head resting against a supply crate.
Aeris looked at him first. "You're back."
"Yes."
"You were out for a long time. Over four hours." She studied his face, her eyes narrowing slightly. "You look... clearer. Sharper."
He didn't respond. Instead, he scanned the banks for "Sign." No clustered movement. No broken branches. The migration hadn't followed them into the water.
Nera stirred. Her eyes opened slowly, blinking against the morning glare. For a split second, her gaze flickered to the spot on the bench where he had been resting his head. A faint, uncharacteristic flush rose in her cheeks.
"You actually slept," she said softly, her voice still thick with sleep.
"I did."
"Good."
Lufias hesitated. The "Calculator" told him to be professional, but the "Human" won the toss. "...Thank you, Nera."
The words were simple, but in the silence of the river, they carried weight. Nera's smile was smaller than usual—not a joke, but a quiet acknowledgment. "Anytime, Boss."
The Compression Point
By mid-morning, the river changed. The wide, lazy banks began to pull inward, squeezed between two jutting rock formations that looked like broken teeth. The current hissed as it compressed, the boat's speed picking up instinctively.
Lufias stood up, balancing his weight against the sway. "Angle left, Kaelyn. Get us out of the center."
"Why?" Kaelyn asked, struggling to keep the pole from being swept away by the force of the water. "The center is faster."
"Debris collects in compressed flow," he barked. "The fastest water carries the heaviest weight."
As if on cue, a dark, jagged shape surfaced in the middle of the channel. A partially submerged log, thick as a man's torso, was rotating slowly in the current like a predatory shark. If they had stayed in the center, the hull would have split like a seed pod.
Lufias grabbed a second pole, planting it hard against a submerged rock and pushing with every ounce of his strength. The hull scraped—a terrifying screee of wood against stone—but they slid past the log and into the slower, safer eddies near the bank.
Nera let out a breath that sounded like a whistle. "That would have flipped us."
"Yes," Lufias said, wiping sweat from his brow.
Aeris looked at him, her expression a mix of curiosity and respect. "You 'dreamed' about river physics too, didn't you?"
"I prepared."
The Signal
By midday, the forest thinned. The air lost its damp, mossy scent and was replaced by something sharp and acrid.
Ash.
Lufias signaled for silence, his hand rising. Far beyond the next bend, a thin, controlled column of smoke rose into the sky. It wasn't the chaotic, spreading black smoke of a wildfire. It was narrow. Vertical.
Deliberate.
"Human," Aeris whispered, her hand moving to her bow.
No one was shouting. No one was waving. There was just the smoke—steady and organized. It suggested structure. It suggested people who weren't just surviving, but settling.
Lufias adjusted his rifle strap. Attachment was a risk. Isolation was a death sentence. He looked at the three girls beside him. He wasn't just calculating their utility anymore; he was counting them as his own.
"We approach with a zero-noise profile," Lufias said. "Rifles low, eyes up."
As the river carried them around the bend, Lufias felt the equation of the Silent Delta change once again. For the first time since the city fell, they were no longer the only thing moving.
Something else was waiting in the South. And this time, they would have to decide: Are we neighbors, or are we targets?
