Quotes
"Evil Bob: The Word of Kemmler contains: 'Knowledge. Truth. Power. The master wrote down his teachings, wizard, so that those who came after him could learn from him. Could learn about the true power of Magic. What you call magic is nothing more than parlor tricks beside the power to master life and death itself.'"
