Going back a few days, the twins had just entered the hole in the hull and began navigating their way through the Air Ventilation of the Airship, one among countless others. Rean, Roan, and Luan crawled through the ducts, which branched off several times.
"Can you determine which direction the Vruve Organization members went, Luan?" Roan asked, unsure of which passage to follow.
As it turned out, the Air Ventilation Ducts were completely clean, devoid of any dust. Dust that Roan could have used to know which direction the Vruve Experts went. Noticing this, Rean took some dirt from the Dimensional Realm and let it fall to the ground to test it. Sure enough, the dirt was absorbed, albeit very slowly. Still, this rate of absorption was more than sufficient to ensure the ducts remained spotless. This also meant that the experts from the Vruve Organization, who had entered an hour earlier, hadn't left any traces behind.
