I am an Archivist. Through blank books, I pull from my visitors their knowledge or imaginations for my book collection. It depends on what the person can give me. I do it secretly and painlessly. The visitor should only read my book while I stand behind his back, put my hands on his head and put all his knowledge that I am interested in into a blank book. In return, I offer to answer any three questions he may have. If the human protests, I lock him in the labyrinth of my library.
