Headmaster Kittley and Professor Cullen have come together to try an experiment. As the Cullens have spent years living a vegetarian lifestyle, their influence has spread to many others and together, the two have decided to try their experiment at Hogwarts. The Night Class was created for vegetarian vampires to maintain a lifestyle submerged with humans, in hopes that maybe, one day, the two can live together peacefully.

Only the Headmaster and the Cullens know of the vampire presence, except for two students. Adalia Leigh and Tatsu Szabo are the Student “Night Guards”, with powers higher than the Prefects. Their job is to ensure that students remain indoors at night and to keep the humans and vampires at a safe level. At meals they ensure that vampires don’t reveal themselves to humans and it is their duty to try and prevent humans from learning of their existence.
