Shop Atmosphere

“The Thunderous Cog is a riot of sound and motion — pistons hiss, miniature automatons scuttle about polishing wares, and Tamsin herself speaks rapidly while tuning a half-finished rifle. Shoppers are sometimes startled as a bellows erupts or a clockwork bird chirps a greeting. Each item is signed with an intricate copper filigree bearing Tamsin's personal mark, and she won’t sell to those refusing a quick demonstration of the item’s safety valves.”
