The Chute of Unspoken Prayers

Deep within the frostbitten jagged peaks of the northern divide stands the Grand Relay of Valtaari, a colossal nine-story vertical cathedral of cast-iron pipes, deafening steam flues, and pneumatic dispatch chutes built directly over an abyss. Here, senior mechanist Lemmilt treats the transit of final letters as a sacred duty, diagnosing clattering brass canisters and tracking pressure drops while screaming sorting codes over the din of roaring boilers. But beneath the grated catwalks, the ancient gods of quietude are waking. Niininen, an apostate monk who believes all spoken grief is an agonizing contagion that must be smothered, infiltrates the flues to cut the steam lines and silence mankind forever. When grease-sealed inspection hatches reveal sodden wads of human hair and dry paper-skinned specters creeping out of the vacuum tubes to stitch living mouths shut, the two bitter adversaries find themselves locked in a vertical labyrinth where keeping the steam draft roaring invites the divine wrath of absolute silence, and shutting it down unleashes the suffocating dead.
