The silence of a biased man (Severus Snape)

Ten years after the events, the wizarding world was slowly recovering from the loss of loved ones. Voldemort's death had significantly reduced the number of Death Eaters, but some remained loyal to him. On the wizarding side, the death of the greatest wizard, Dumbledore, had brought tears to many eyes.
Severus Snape had managed to survive the attack by Nagini, Voldemort's snake, much to his dismay, as the wizard would have preferred to die from his wounds. His slander had led to dramatic falls in the wizarding world.
