Having just eliminated that group of skeletons, Wesson observed the color of the Soul Flame in each skull's eye sockets as he absorbed it, carefully recording the information.
Once Wesson had absorbed all the Soul Flames from the bound skulls, he confirmed that most of the absorbed flames were white, with only a small portion being Green Soul Fires, and no higher-level Soul Flames were discovered.
Based on the information reported by Wesson, the staff at Command Headquarters quickly deduced that the fog must be controlled by higher-level skeletons and therefore, there must still be higher-level skeletons within the fog.
As for the patch of ground fog, Zachary could now see it very clearly; although there weren't just one or two skeletons left in the fog, only about three to five remained.
Among them, a robust skeleton, whose eye sockets were filled with Red Soul Fire, clearly commanded the other skeletons gathered around it, without the need for further explanation.
