In the Harry Potter series, Severus Snape, known primarily as the Potions Master, turns out to be much more than that. During Harry Potter and the Half-Blood Prince, Harry discovers a potions textbook that aids him in excelling in Professor Slughorn’s class. At first, Hermione is puzzled by Harry’s sudden proficiency, but she later comes to understand that it was not Harry who had mastered potions, but rather the book itself – previously belonging to a student known as the Half-Blood Prince. This discovery adds depth to both Harry’s background and his overall role within the storyline.
