<P> When Harry reported that Voldemort had returned , towards the end of Harry Potter and the Goblet of Fire , Dumbledore reactivated the Order . Many of the original members returned and were soon joined by recruits who effectively replaced those who had died in service during the first conflict . The Order established their headquarters at Number Twelve , Grimmauld Place , Sirius Black 's family home , during the interval between the fourth and fifth books in the series . Dumbledore was the Secret - Keeper for the Order , meaning that only he could reveal the location of the Order 's headquarters to others . Dumbledore 's death in book six made the location vulnerable and it was abandoned in favour of The Burrow as a result . </P>
