Okay, I have a great idea about writing how a portrait got its start, but I really need some help in that- how do they come about? Is there a spell that allows portraits to be able to move around and talk and have all of those memories that their living counterparts had? And in the headmasters' room, do the portraits just suddenly appear on the wall when the headmaster dies, or does someone put up an existing portrait of said headmaster? Anyone with information, or even speculation, please help!
