Neph leads the group back the way they had traveled, until coming to that intersection with the tunnel that descends at a downward slope. She takes this path, leading your group into complete darkness, without even the illumination of the fungii that was prevalent in the tunnel above. For those of you that can see, or whosoever lights a torch, this tunnel descends deep, traveling on for what seems like miles, and it takes hours for you to find much in the way of a landmark. When you do, however, it is a grand one...
After a couple hours, the tunnel opens up into a massive cavern. Humongous crystals hang down from the ceiling, reflecting a bluish glow from some unseen light source. The cavern itself extends out to the left and right for hundreds (potentially thousands) of meters. Exiting the cavern is a land bridge that spans the gap to a tunnel entrance on the far side, perhaps some three-hundred feet away. To the left and right are other such land bridges, connecting other tunnels, though they are far beyond your reach. The descend to the bottom of this cavern is a sharp one, and a steep fall of approximately sixty feet, or more.
Notably, the cavern floor to the right is dominated by the ribcage of a titanic beast, which likely drew to heights of a hundred feet or more. One of these curving, spiked ribs juts up just beside the land bridge you stand upon. It appears as though runes are carved into the thick, massive bone.
Neph leads you out onto this land bridge, calmly walking you across. As you have been traveling, she has occasionally spoken to you in her native language before remembering that you cannot understand her. She does, however, regularly check back on your group to make sure everyone is following close.
