Patronus (magical guardian)

A Patronus is a magical guardian creature from the Harry Potter universe, conjured through advanced spellcasting. It serves as a protective (defensive) charm that repels Dementors, dark creatures that drain happiness and life force. The Patronus embodies positive emotions and can be summoned by focusing on one's happiest memory. It often takes a distinctive form, such as an animal that symbolizes the caster’s personality or attributes. A Patronus acts as both a shield and a beacon of hope, reflecting inner strength and resilience against darkness.
