The Resonance in the Plaster

In the subterranean metropolis of Yil-Olgur, silence is the only law that keeps the foundation from cracking. Deep within the exhaust conduits, sound-scrubber Temuroglu and his crew spend their shifts scraping sonic residue from the air vents. But lately, the pipes have begun singing back. An invasive, multi-voiced entity is nesting in the hollow infrastructure, whispering a rhythmic occult cadence that compels anyone who hears it to claw through their apartment walls. As entire residential tiers fall into synchronized delirium, Temuroglu, Saribek, and Altantay must navigate the darkening shafts to sever the city's acoustic conduits before the walls finish forming teeth.
