As Nova and Kai ventured further into the outer depths of the Labyrinth, with new and old paths opening and shutting, Nova smelled the faint scent of cologne. He tracked the cologne until they found another opening, where there was a freshly lit fire that had now dispersed, meaning that there was definitely someone there.
Kai inspected the area, realizing that there were faint traces of blood lingering on the floor of the labyrinth, suggesting that whoever was here was either being hunted and needed a place to hide and rest, or had suffered some damage previously and set up a temporary camp. Another option that he could think of was that they had just fought in this opening, and the freshly lit fire was from a fire manipulator, who might have suffered some injuries.
