SCENE 1: 350 years ago a sorceress casts a curse of great power that forms a great dark wall between the upper city and the slums. The wall traps not only sunlight, but also the flow of magic and health. This leaves the people in the upper city "overdosed" on magic, living forever, almost zombies. The people below the wall are still passionate, but they have little health or sunlight. Reader doesn't know all the details of the curse.
