((Yeah. I had Obsidian in mind, but I don't know much about rocks, so I didn't want to name any specifics))
Delano rushed to Muroki, and looked down to where his brother was pointing. His eyes widened when he saw the large amounts of the black rocks at the bottom of the cliffed off area. "Yeah, I believe those are the rocks!" He said, smiling. But then his smiled dropped when he looked at the cliffs surrounding the rocks. "But how do we get down there? And if we do, how will we get back up?" He asked.
It only figured that they found the rocks quickly enough, but they were at an area that was nearly impossible to get to. Now Delano tried to figure out a way to get down the cliffs, and more importantly, back up, but he didn't see any path that they can walk on to get to the bottom. "I don't think we can get down there," he said uncertainly.
