In the "Chamber of Secrets", Draco reveals that the manor has its own "chamber of secrets" under the drawing room, which was used to hide valuable dark artefacts when the Ministry raided the manor. Voldemort used Malfoy Manor as headquarters on at least one occasion in "Deathly Hallows". The three Malfoys seemed quite displeased by this use of their manor as Voldemort himself noted; only Bellatrix appears to be pleased he is there. The Malfoys have become prisoners in their own home and are in very real fear for their lives. During the "Deathly Hallows", several prisoners are being kept in the basement on Voldemort's orders, including Luna Lovegood, Dean Thomas, Griphook the Goblin, and Mr. Ollivander. When Snatchers capture Harry, Ron, and Hermione, they are brought to Malfoy Manor. They escape with the other prisoners thanks to Dobby's help. The four residents of the manor are then placed under house arrest by Lord Voldemort, until they join with other Death Eaters in the Battle of Hogwarts.
