Raydon had just begun to run when, ten minutes later, he stopped and muttered to himself. 'I suppose there's something nearby.'
He was getting further and further away from the waterfalls when he first became aware of a new sound. It wasn't like the waterfalls' continuous roar; rather, it was more of an intermittent sound. The fact that the ground would ever so slightly shake whenever the sound was produced is evidence that it was something powerful.
Raydon couldn't help but feel curious when he heard this strange sound, and he began to move in the direction that the sound was coming from. The enigmatic sound that was getting louder and louder drew him forward and kept him moving. In addition to the loud boom that he could hear, the shaking in the ground that he could feel was also accelerating at the same rate.
