The next day.
London Academy of Magic.
Aaron opened a dimensional crack and appeared in Jackson's study, saving him some travel time.
It was ten in the morning, Jackson was not in his study. Aaron guessed that he was teaching a class.
While waiting, Aaron stepped closer to the bookshelf and searched for books that were relevant to the information he was looking for.
There were many things Aaron didn't know about the situation on Earth after 12 years away. He needed the books to fill in the missing information.
He opened a book with the title of the history of mage groups in the World. It was possible that Aaron would get important information when he opened the book.
Aaron sat on the single seat sofa and opened the book sheet by sheet.
There are many histories of famous mage groups founded in several unions, some focus on defense and security, there are also groups that focus on alchemists and science.
