Hey Cyril,
I got the idea more than ten years ago. I don't know where I got it. I guess I was reading about the seven deadly sins in some medieval literature.
Over the course of that time I made up alot of material for the world. Then, in October-november of 2001 I made the site because I figured some people might be interested in seeing it, and as a resource for my P&P game, and it has been going strong ever since.
