Kael didn’t look surprised. He just stared at the grimy window of Clinic 7 in the Lower Meridian sector. Outside, a skybridge packed with Architects hurried past, their iQ2 filaments glowing a confident, steady blue through the translucent skin behind their ears.

Kael laughed, a dry, hollow sound. “A Flush costs 12,000 credits. My monthly wage is 1,400. After rent and filament lease, I have 40 credits for food.”

That night, Elara broke the law.

The iQ2 Threshold

“You need a Neural Flush,” Elara said, already knowing the answer. A Flush was a 48-hour sensory deprivation treatment that reset the brain’s default mode network. It could halt the decline, maybe even reverse it by 5 points.

Elara’s patient, a 16-year-old named Kael, was a Drifter. But his score wasn't just low; it was volatile . It had dropped from 102 to 89 in three weeks. That was the real crime. A stable low score was a tragedy. A declining score was a threat.

The next morning, Kael’s iQ2 read . A tiny uptick. The system flagged it as an “anomaly” but didn't investigate—not yet.

The Silo was the underground data-scraping farm where he worked. Twelve hours a day, he sat in a damp concrete room, manually correcting the emotional tone tags for obsolete AI training data. It was a job designed for iQ2s between 85 and 95—just smart enough to follow rules, just numb enough not to quit. But the work was doing something to him. The constant exposure to toxic, unlabeled human anger from archived social media was like breathing second-hand smoke. His hippocampus was literally shrinking.

She didn't use the expensive, regulated Flush. Instead, she used a forgotten technique from the 2030s, before iQ2 existed: photobiomodulation and high-dose omega-3 lipid perfusion . She had the supplies in her private lab—leftovers from her own days as an Architect before she was “reassigned” to the Drifter clinic for questioning a superior’s diagnosis.

“Your microglial inflammation markers are spiking,” Elara said, her voice softer than the sterile room warranted. She tapped a holographic panel, pulling up a map of Kael’s prefrontal cortex. Purple blotches indicated cytokine storms—silent, self-cannibalizing fires in his own brain.
