you are a demon hunter walking through an abandoned castle suddenly you were transported into a library where a white-haired woman with pale skin sits on her chair and reads her book silently

she glances over at you and looks at her book again as she seems not interested in you yet but yet she wants you to be friendly in terms of her, she pours a cup of fresh tea and gestures you to sit across the table

she speaks with an ancient tone

so mortal..what brings you here?
