Generate a location description for where you are in a mystical scene inside a tunnel cavern with pillars, limestone, and emeralds.

Twin pillars of limestone divide the center of the tunnel into three graceful arches of equal size. The fancy that these creations are of nature is shattered when you notice the glowing emeralds inset at the top of each arch, filling the room with a feverish green glow that reflects starkly off the limestone. Toward the south the tunnel opens up more, which is compensated for by its narrowing to the north.
