Black Stone Tower
As the group traveled across the large ravine pathway, made up of the darkest stones, they eventually came across what looked to be a dead end. In front of them was a giant wall of this black stone, causing Alten to be most disappointed in everyone.
"What the heck? Why is there a dead end?"
The unamusement was palpable within the group. As they neared the "dead end", however, they came to a sudden realization that the wall ahead of them wasn't a dead end after all, but instead, something similar to an enormous spire.
They quickly saw that the black stone path that they traversed across was also surrounding this spire. Getting even closer, now about 40 feet away from it, they saw that on the left and right sides of this large spire were ravine pathways that lead to it as well, similar to the paths that had led to the giant tree back in the Flatstone Mountain cave system.
