The Last Horcrux | Harry Potter Fanfiction

It was unknown to everyone that Morfin Gaunt, son of Marvolo Gaunt, had married a witch and had a daughter named Morgana Gaunt. Morgana had been living in the secret basement her grandmother built ever since the day she got news of her father found dead in Azkaban.

With nowhere to go, she heads to the same orphanage Voldemort went to and found him scanning the perimeter of the cave near the orphanage. Voldemort had tried to kill her with the Unforgivable Curse, Avada Kadavra, but fails. Only to mark her with a star on the nape of her neck. This mark, making Morgana another one of Voldemort's horcruxes.

Traumatized, she's been staying in the orphanage ever since.
