Lore

The Tome of Deduction is a legendary book that was written by a master investigator known only as "The Eye". The Eye was a mysterious figure who solved many crimes and mysteries across the lands, using his keen observation, logic and intuition. He was feared by criminals and respected by law enforcers, but he never revealed his true identity or motives.

The Eye was also a generous teacher, who wanted to share his knowledge and skills with others who had a passion for investigation. He wrote the Tome of Deduction as a comprehensive guide to the art and science of finding clues, analyzing evidence, deducing facts and uncovering secrets. The book contains puzzles, exercises and techniques that challenge and improve the reader's investigative abilities. The book also has a magical property that adapts to the reader's level of proficiency, revealing more secrets and benefits as the reader progresses.
The Tome of Deduction is a rare and valuable item, sought after by many who wish to learn from the Eye's wisdom. However, the book is also a test of the reader's dedication and morality, as it only reveals its full potential to those who are worthy.
The Eye's fate and whereabouts are unknown, but some believe that he is still alive, watching and judging the world from the shadows. Some also believe that he left behind other clues and secrets in his book, waiting for the right person to discover them. The Tome of Deduction is a treasure for those who seek the truth, but also a challenge for those who dare to face it.
