robably expecting this observation of yours, your counterpart now falls into a lengthy explanation to fully justify himself:
"Uuuuh, the robes help me to scare away the nosy peasant folk who come here to convince themselves that a demon lives inside these walls. Unfortunately it's completely useless against the so called 'noble adventurers' like yourself who don't believe in demons and who feel less complete if they haven't ruined someone else's perfectly fine day yet. But you, my special friend, you don't look like much of threat after closer examination, so If you excuse me now, I have work to do! You can roam the estate as long as you don't breath away too much of the air in my workshop. It is thin as it is already up here."
Not being ready to leave quite yet, you try to keep the conversation going: "If you allow me another question:", you therefore ask: "Why do you need so many statues made of wood?"
