A Patronus is an advanced form of magic that can take a corporeal or non-corporeal form. Sometimes conjured from a powerfully happy memory, it can be used as a shield from DementorsTM due to its incredibly positive force. Fun fact: Remus Lupin’s Patronus is a wolf and when Nymphadora TonksTM fell in love with Remus, her Patronus changed to match his.
