Puber was actually relieved by the departure of this large group of people. The individuals named Xerob and Uma, along with their followers, were constantly appearing and disappearing, like ghosts. Although he wasn't sure what exactly they were up to, the gloom and cold brought on by their dark natures always made others uncomfortable. This bunch seemed to have contributed nothing to the betterment of Caucasus and Leon. Their leaving must have been related to the Boss's news. Sending them to the Boss's side may be for the best; perhaps only the Boss could get them to settle down and do something meaningful.
