HP: Dangerous Professor from Azkaban Novel

Expelled from Hogwarts. Imprisoned in Azkaban. Forgotten by the world. Sagres Greengrass was a name whispered in the Wizarding World with fear and awe. A half-blood from a pure-blood family. A prodigy who created spells no one dared speak aloud. A genius who crossed every line in pursuit of knowledge—and paid the price. Branded dangerous, he vanished into the shadows of Azkaban. Five years later, he returns—not as a student, but as a professor. Sagres Greengrass is a transmigrator. As a member of a pure-blood family in the magical world, his first experience of magic came from a Cruciatus Curse cast by his mother. When he wanted to seek help from his father, he found out that his father was a Death Eater. Imprisonment in Azkaban did not leave him with madness and corruption, but rather a kind of chilling elegance. With the power of forbidden knowledge, a mind sharpened by torment, and secrets only a dark wizard could know… The Dangerous Genius is back. ______ Support the translation and read Two Weeks/12 chaps ahead at- Patreon/DarkDevil1
