Aurors were highly trained witches and wizards working for the Ministry of Magic as law enforcement officials. With a focus on dark magic, Aurors were highly skilled in Defence Against the Dark Arts as well as how to apprehend and detain dangerous dark witches and wizards. When Harry Potter became involved in defeating Voldemort after his return, he was helped by Aurors such as Nymphadora Tonks, Alastor ‘Mad-Eye’ Moody and Kingsley Shacklebolt, all of whom were willing to risk their lives for the cause they believed in.
