Please generate a brief description of a gloomy scene outside a cave with lichen and torches.

Walls covered in a faint dusting of lichen, the tunnel narrows slightly as it divides in two. The larger tunnel continues to the north, while a smaller branch veers west. A slight, almost imperceptible breeze comes from the direction of the larger tunnel. Along the walls, a string of torches disappears around both bends of the tunnel. Visible to the south is a tunnel entrance which opens into a larger cavern with a shaft of light coming from the ceiling.
