The traitor in the Order of the Phoenix was Kreacher, Sirius Black's house elf.
Kreacher's betrayal of the Order of the Phoenix was a significant event, detailed in the context of the struggle against Lord Voldemort. His actions were a direct result of an unfortunate command given by his master, Sirius Black.
Details of the Betrayal
- The Perpetrator: Kreacher, the ancient and devoted (though grudgingly so) house elf of the Black family.
- The Circumstance: The betrayal occurred when Sirius Black, in a fit of anger, inadvertently gave Kreacher an order that removed his usual restrictions and explicitly permitted him to communicate with other members of the Black family, specifically Sirius's cousin, Narcissa Malfoy.
- The Impact: This seemingly innocuous permission allowed Kreacher to relay sensitive information about the Order of the Phoenix to Narcissa Malfoy, who was a Death Eater sympathizer and mother to Draco Malfoy. Narcissa, in turn, used this information to aid the Dark Lord's forces.
This act, while not intentionally malicious on Kreacher's part initially (he was bound by the magic of an order), had severe consequences for the Order, demonstrating the far-reaching impact of even seemingly minor magical commands within the Wizarding World.
