Sirius's mother. Though she's been dead for twelve years at the start of the novel, she appears in her portrait in number twelve, Grimmauld Place. Her portrait isn't entirely sentient, but it screams obscenities about Mudbloods and half-breeds whenever someone rings the doorbell or makes too much noise. In life, she was obsessed with blood purity, and on the Black family tree, she burned off the names of family members who offended her by not buying into the same ideology.
