The Paths Through the Underground/Underdark (9 Days of Travel)
Wandering through the dark tunnels, the rushing sounds of the underground river begins to fade as it diverges from the cavern. You walk on for miles, the smell of hard water and wet earth. Natural chambers and cavern passageways are chained together by the stretches of burrowed earth left in the wake of this massive worm-like creature. Clusters of crystal and other beautiful minerals occasionally line the walls and ceilings of the chambers, glittering with the little light you have to shove back the darkness.
