Tomes and Tribulations
In this walkthrough for Hogwarts Legacy, we'll give you the complete tutorial for the main quest: Tomes and Tribulations.
Once you've discovered the secret, return to Professor Fig's classroom and bring the book you found in the Library Restricted Section to Professor Fig's office.
Professor Fig realizes that there are pages missing from the book. He has to go to London to speak to the Ministry about George's death. He will take the book with him to do more research. In the meantime, Professor Fig will ask you to find out more about the missing pages on your board and do well in your lessons.
And so the quest: Tomes and Tribulations comes to an end, making way for your next main quest in Hogwarts Legacy: Herbology Class.
The friends you make can also teach you many things, including spells (indeed, as was the case when you learned the Disillusionment spell from Sebastian).
