Hogwarts: The Book of Laws

"What is darkness? What is light? When you do something that is not in the public interest, you are darkness; when you do something that is in their interest, you are light." Lean held his head with his hands. He said with interest, "But only the weak need to live in groups. Tigers always come alone."
ps: I won’t join the group, the heroine Hermione.
Originally I didn’t want to have a female protagonist, but Emma is too beautiful, sorry.
