Acoustic Command Post

True authority requires instantaneous communication across expanding territories. Advancing past our perimeter barrier along the varnished plank, I discovered an abandoned silver metal thimble and a discarded wooden cocktail stick near a cloth-bound encyclopedia. Planting my boots firmly against the shelf grain, I gripped the wooden shaft with my green right hand and slid it through the natural crevice between the floorboards. With my gray left claw, I hoisted the dimpled thimble and inverted it squarely over the upright stick's rounded head. Striking the alloy dome produced a sharp, resonant gong echoing down to the lower plains. Command signals are operational.
