SILT-BASIN . 2 June 2729

Bolat Abiodun has blocked the eradication of a red lung mould.
The Silt-Basin Heritage League declared on Wednesday that the dry hacking cough caused by the spore is a protected acoustic landmark.
Abiodun spends his mornings patching the raw clay walls of his dome with a resin scraper. Every three minutes, a deep, rattling wheeze shakes his thin frame, echoing off the bare vinyl beams. This dry rattle, once common to the first generation of dome-builders, has almost disappeared as newer air scrubbers are installed.
"Modern lungs are far too quiet," Abiodun said, scraping a fresh layer of grey slime. "There is no soul in a silent dome."
Sanitation crews had planned to spray the raw clay tunnels with fungicide to clear the settlement. The mould causes permanent lung scarring but is otherwise harmless to the clay foundations.
Clinic manager Mateus Amankwah confirmed the spore is fatal to newer settlers, but remained cheerful.
"It is a slow suffocation, but it does wonders for the local soundscape," Amankwah said.
Abiodun has already begun training school groups to cough in unison in the clay tunnels.
The children who ask for water are scolded for ruining the acoustics.
