The branch manager of the Three Fanged Shadow Hall assassin looked at Nathan but found nothing from his face.
"Haha, Its the servant key that is given to the most loyal servant of the house, Nehmor. My father gave it to butler Francis when he was still the Patriarch of the house. I never took it since he was still the most loyal servant, but alas, now that he is dead, I have to appoint another one now." Nathan explained. He knew not to fuck this up, so an explanation about the Key came tight off the bat. He did ask for the Key so that he does not look too eager.
"...Hm," The branch manager placed the Key to the side of the table while Nathan also acted like it was nothing worthwhile, so he never took another look at the old rusty Key. It was because he believed Nathan's words. Nobles had some weird tradition that could never be understood by him.
