Harry reports Malfoy's declarations to Minister Fudge, who refuses to believe him. Later in that book, when Voldemort rises again and summons his Death Eaters, Malfoy rejoins him and asserts that he had done everything he could to help his master, who however remains unimpressed. Lucius next appears in the beginning of Harry Potter and the Goblet of Fire during the Quidditch World Cup, sharing prime seats in the Top Box with Minister for Magic Cornelius Fudge. Despite his sacking, he still maintains strong ties with the Ministry of Magic. Lucius is ultimately stripped of his title as a Hogwarts school governor. Upon this, Lucius attempts to attack Harry with his wand but Dobby disarms him before he can do any harm. Subsequently, Harry tricks Lucius into setting Dobby free. Lucius' plans are ultimately thwarted with the help of the Malfoys' house-elf Dobby, and Harry, but not before the Chamber is opened and Lucius uses the ensuing terror (and threats to attack their families) to influence the school's Board of Governors to discredit and dismiss Dumbledore as Headmaster. Lucius intends to use the opening of the Chamber of Secrets by Ginny to discredit her father, Arthur Weasley, and Dumbledore. He is careless with it and punished by Voldemort himself. Lucius knows the diary is cleverly enchanted, but is not aware that it is a horcrux containing a part of Voldemort's soul. He debuts as the main antagonist in Harry Potter and the Chamber of Secrets, in which just before Draco and Harry's second year at Hogwarts, Lucius plants Tom Riddle's diary in Ginny Weasley's potions cauldron while she is shopping for school supplies at Flourish & Blotts, in a plot to use her to reopen the Chamber of Secrets, which would lead to attacks on Muggle-born students. He was educated at Hogwarts, where he was a prefect in Slytherin House. To maintain his reputation and influence, he makes donations to the Ministry, to charity, and to St Mungo's Hospital. Lucius was a school governor of Hogwarts before being sacked, and has very close connections at the Ministry of Magic.
He lives with his wife Narcissa Malfoy (née Black) and their son Draco at the Malfoy Manor in Wiltshire.
Lucius Malfoy is a Death Eater, head of a wealthy pure-blood wizarding family and a psychopath.
