You shouldn't treat familiars as if they were simple servants. They are irreplaceable companions deserving of trust. They are the rescuers of lonely old magicians, saving them from a life of solitude. —Familiars: An Introduction, Chapter 1
Do not depend on their devotion, for that is not their purpose. To truly be a good fit for your familiar, you must work to improve yourself. Only then will your familiar's power increase. And wouldn't that be handy? —Familiars: An Introduction, Chapter 6
