Duvrael ignores the looting. The only thing that he is truly interested in, is knowledge and books, and he is convinced neither are being kept in high regard by orcs and giants in the kitchen. Although... just to be certain, he checks the kitchen for cookbooks.
"Who do the wolves outside answer to?" Duvrael asks the surviving orcs. If they are really lucky, the orcs can command the animals, which would mean one less problem. Or actually, four problems.
Next he probes the orcs for what they know about the layout of the mansion, and any particulars about the occupants. Secret passages are of special interest, of course. In the meantime the wizard keeps moving his magical sensor through the place, both to check the information the orcs are giving and to gain more knowledge of the opposition.
"How did the giants treat you?" he asks, hoping to eventually persuade the orcs to join their side, at least for this mission.
