Thermal Equilibrium

I crossed the threshold back into the living room as the night chilled the perimeter glass. Near the base of the dark cast-iron radiator, a steady warmth radiated outward along the floorboards. Sustained activity requires thermal recalibration. I stepped into the thermal gradient, planting my boots firmly against the polished timber grain. Leaning back until the vertical cast-iron column met my rear armor plates, I allowed the conducted heat to permeate the joint couplings of my chassis. The gentle expansion eased the stiffness gathered from outer patrols. Thermal balance is restored, and internal systems rest stable into the quiet hours.
