“The Ministry has fallen. Scrimgeour is dead. They are coming.”
-- Kingsley Shacklebolt's Patronus messenger, warning wedding guests that Death Eaters were about to arrive (DH8)
This unnamed messenger spell sends the caster’s corporeal Patronus to bring a message to others.
History and Notes
This magical method of communication was invented by Albus Dumbledore as a way for members of the Order of the Phoenix to send messages to each other. Because only Order members knew how to cast this magic, the recipients would be assured that the message was genuine (JKR).
