“To say that I knew her would be an exaggeration. I think, except for the witcher and the sorceress, no one really knew her. When I first saw her, she did not make much impression on me, even despite the rather unusual accompanying circumstances. I knew people who claimed that right away, from the very first meeting, they felt the breath of death coming from this girl. She seemed completely ordinary to me, although I knew that she was not ordinary, so I persistently tried to discern, discover, feel the unusualness in her. But he didn’t notice or feel anything. Nothing that could become a signal, foreboding or a harbinger of later tragic events. The reason for which she was. And those that caused herself. ”
