Lenore has grown up, and chose her favorite activity as a job, she has become a librarian. This way she can spend all of her time with her books.
Lenore became a librarian, so she needs a few things for it. She opened her own library, so Nevermore can always be with her, because they can't separate easily. They can spend their days together, and do their most favored thing: reading. Of course they mostly read their beloved book... the Raven.
