You pass through the golden mouth, and find yourself inside a narrow, cramped corridor. Large wooden paintings of skeletal hands crook their bony fingers, leading you forwards. At the first turn, you hear a bizarre jumble of sounds: the high-pitched sound of gears grinding, metal on metal, the sound of sultry, low-pitched laughter, a clattering, wings flapping, soft hissing. Suddenly, a sharp howl pierces the darkness. As you make your way around the corner you are momentarily blinded as floodlights flicker to life, and thirteen gold-gilded stages are illuminated, bathed from beneath in sinister, caramel-colored light.

Dust, incense, wet tobacco, singed straw, and a curl of opium smoke.
