"There has always been a rumor in Hogwarts. Legend has it that a ferocious red dragon lives nearby, and it makes a living by preying on ferocious beasts. Whenever night falls, it will crawl out of its underground lair and fly wantonly in the air, looking for prey. Until one day, this evil dragon appeared in Hogwarts and turned into a little wizard. No one knew his true identity. Whenever night falls, this evil dragon will wander around every corner of Hogwarts, looking for students who wander at night, and devour them in one bite. All people can find are a few tattered school uniforms..." - Argus Filch
