Eventually, Shang came up with an idea, but it wasn't a very good one.
"We could just make copies of the book and dump them all over the Kingdom," he said. "Nobody would be able to link it back to us."
"That's wrong," the Dean said. "The Spell to copy the books leaves traces of someone's aura behind. Whoever copies the book will be found by the Dukes, and they will undergo a Mind Read. In the end, it will be linked back to one of us."
"Even if we send a proxy and kill the proxy after making the request, the Mages aren't stupid. They know what will happen if they copy this book. As soon as they get their hands on the book, they will immediately report it to their superiors."
"Additionally, it requires a lot of resources to make copies of books. We would need a True Mage, and they would never accept the request."
