Snapes reflection goes from light to dark

Harry, Ron and Hermione continue their quest to vanquish the evil Voldemort once and for all. Just as things begin to look hopeless for the young wizards, Harry discovers a trio of magical objects that endow him with powers to rival Voldemort's formidable skills.

Harry, Ron and Hermione walk away from their last year at Hogwarts to find and destroy the remaining Horcruxes, putting an end to Voldemort's bid for immortality. But with Harry's beloved Dumbledore dead and Voldemort's unscrupulous Death Eaters on the loose, the world is more dangerous than ever.

Flashing lights illuminate black faces and dark eyes, oscillating between darkness and inverted lightness.
