My screen says:
You tear up the tunnel, leaping rocks that jut up from the floor, leaving the chasm behind. To your dismay, you hear the hissing and grating of rock that signifies that the dragon is not far behind. When you end up back where you first encountered the dragon, a giant claw lashes out, barely missing you. You duck to the side, and the dragon's massive bulk races by before turning again to face you.


There is a hulking smoke dragon here with evil red eyes that bore right into you. Thick smoke, gray and brown, emanates from its skin, and more puffs from its mouth in regular intervals. It lumbers toward you, shifting shape and form as it goes to navigate around the uneven confines of the tunnel. It doesn't seem real, you realize with even more fright; its body seems alternately firm and insubstantial.
Suddenly the dragon lets out a deafening roar that nearly scares you out of your wits. You frantically ready your sword, and the dragon lunges at you with its serpentine head.
