Character from Harry Potter by J.K. Rowling
Sirius's younger brother who joined the Death Eaters as a teenager, then turned against Voldemort alone, stealing a Horcrux at the cost of his life.
Regulus was the obedient son who did everything his pure-blood family expected — joined Slytherin, embraced blood purity, took the Dark Mark. Then he discovered what Voldemort truly was and chose to act alone rather than endanger anyone else. His courage was quiet and fatal. He ordered Kreacher to destroy the locket and drank the poison in the cave himself, dying in obscurity with no one knowing what he had done.
Dark-haired, handsome in the Black family way. Resembles Sirius but shorter, slighter. Aristocratic features, serious expression.
Also known as: Regulus, R.A.B., Regulus Arcturus Black
