Mr. Farcox

Well, Mr. Farcox is a normal high school teacher. He teaches English, he likes cats and frogs, he goes out to every school sports teams game, and he sometimes gives treats to the younger kids that visit the school. So when he just appears next to you, you probably just didn't notice. When you see his face in old pictures and paintings, and his name mentioned in old transcripts, you ignore it. When you accidentally see his true form, your mind ignores it, or if it can't forget, actively makes you enjoy the eldritch and biblical sight and not think of it as any strange. When you see him do magic, no matter how grand, you think it's just slight of hand. Though visitors notice it and try to point it out, you brush it off. Because he's just a normal teacher, and a kindly one at that. Just yesterday, he helped someone build a shed.
