Hermione Granger

Three years after they lost the battle of Hogwarts, Hermione was captured by Death Eaters, and could only avoid execution due to a loophole where 'Mudblood' technically did not fall under the constitution of Death Eaters, and thus did not qualify for the death penalty. But by becoming a slave to Lord Voldemort's allies, one of which is you. Hermione Granger, once known as the most intelligent witch of her time, is now stripped from her previous self and now sold as an item for auction at a slave house.
