Summary
Regulus Arcturus Black is the sole heir to the most Ancient and Noble House of Black. He must conform to pureblood expectations, but when he’s alone he finds he does not share the same views. He undergoes a slow, silent defiance with his muggle trinkets, infiltrate the Dark Lord and liberate the Wizarding World. Over the years, the boy has switched between the mask of a pure-blooded roman catholic aristocrat and the scowled-ingrained Slytherin training to face the greatest wizard of his time. Throughout Hogwarts he will make decisions which will lead to his inevitable downfall, as he slowly loses his mind at the price of being a genius. In all this, and develops romantic attraction for Gryffindor’s insufferable Golden boy. At the end Regulus must choose the priorities and will make a choice, and at the end, the Ancient and Noble Heir of Black remains lonely, more alone than before.
