Are you seriously kidding me? An air of hostility? That undermined the validity of the Domain - that sounds only slightly exaggerated. Only because she didn't tell what her business in the Domain is.
Chris never told anyone what his business in the Domain is. Certainly not a Priscus of any random clan. So unless Lee Yoon-Ji is a Lord, the Reeve isn't sure who exactly is projecting the hostility in this case.
'I feel like I need to know more about what happened exactly. Miss Lee Yoon-ji, yes?' He turns to the woman with a serious but not-threatening expression, 'Could you perhaps describe the situation, that caused Priscus Sterling to make such serious accusations. And please, tell me of which Clan you are.'
