oh i've a problem with you, mist

Harry stared at everyone, trying to remember the lecture he had about Demi-gods in the second year with Professor Binns; he could only recall little bits of it that he had to cram for the exam, things like ‘muggle servants of a powerful wizard’ and ‘kicked out in year sixteen hundred something because they wanted more power’ fluttered across his mind. So, he just looked at his friends for a better explanation. Ron noticed his questioning gaze and delightedly explained. “They’ve been said to have vanished after we kicked them out!” Hermione smoothly took over. “The possibility that there is a community of charmed muggle servants,” her eyebrows twitched, “living somewhere hidden by everyone after the events of sixteen eighty-nine is really... interesting.” “Unsupervised for three hundred years!” Ginny joined in excitedly. ___Alternatively:Mist is falling and it's wizards who notice it before mortals. And as they prepare to meet the demigods, they don't realize they have the wrong idea about them and their identity.
