The Black Lord

Walburga lost everything because of him: Voldemort. He took her favorite son, her favorite niece, and her husband from her. But when he was defeated by a mere toddler, the son of a filthy Mudblood, maybe there's a way she can get her revenge on the world. Maybe she can rebuild her family from ruin through a wizard powerful enough to kill a Dark Lord as a baby. Dark!Slytherin!Harry
