Heat Below the Cogworks

As Ironhaven trembles beneath his feet, Theo Voss uncovers evidence that the city’s rulers are drilling dangerously into the volcano’s heart. Racing through sweltering tunnels and fog-shrouded streets, Theo must evade the Council's agents and reveal the truth before disaster erupts, literally.

Theo Voss yanked his wrench free from a rusted valve, wiping sweat and grease from his brow as the pipes above him shuddered. Steam hissed so loud he almost missed the deep, unnatural rumble that vibrated through the steel grating beneath his boots. Lights flickered overhead, throwing jagged shadows down the maintenance tunnel. He glanced at the open hatch beside him, its lock broken, and the Council-marked drilling rig jammed inside. A gloved hand tightened around the evidence as footsteps echoed from the far end of the corridor. Theo shoved the rig into his satchel, heart pounding, and ducked behind the pipe clusters just as a lantern beam swept the passage. The air reeked of scorched metal and hot oil. Somewhere above, another tremor shook loose flecks of rust.

"Who's down there?"

barked a voice, sharp with suspicion. Theo pressed himself against the pipes, holding his breath, every muscle taut as the searcher approached.

Ironhaven is a labyrinthine city forged inside a dormant volcanic crater, where every machine and household runs on scalding steam. The city’s lifeblood flows through pipes and vents owned by the powerful Foundry Council, who jealously guard their monopoly over power and heat. Now the volcano stirs, threatening everything.

Deep within the blackened caldera of Mount Vesper, Ironhaven sprawls in stacked terraces and hanging walkways, choked by copper pipes and shrouded in perpetual steam. The city's stratified society is etched into its geography: the wealthy and powerful live in polished brass towers near the rim, basking in filtered sunlight and controlled climate, while the lower levels lie sweltering and dim, where laborers toil amid hissing vents and looming shadows. The Foundry Council, a secretive collective of industrial magnates, controls access to heat and energy, treating the volcano’s pressure as both commodity and weapon. Ironhaven’s markets bustle with clockwork contraptions, airships drift overhead on warm currents, and rumors swirl of sabotage and forbidden experiments in the city’s forgotten underways. For generations, the caldera has been stable, its geothermal veins tapped for progress, until now. Recent tremors have shaken the lowest districts, causing pipe ruptures, blackouts, and fear. Whispers echo in the alleys: the Council is hiding something in the depths, and some say they risk awakening the mountain itself. Amidst this tension, workers, tinkerers, and inventors navigate a world ruled by steam and secrets, where every clanging pipe might signal opportunity or disaster.
