A thick leather-bound tome, decorated with gold embossing. The pages of the book are filled not only with text, but also with diagrams, maps, and schematics depicting the structure of the human soul. Inside are the sayings of philosophers Feo, grouped not by authors but by questions: "What is good?", "Does fate have a face?", "Why are we afraid of darkness?". It is said that if you read the book from cover to cover, you can find the answer to any question, but by then you will forget what you were asking.
