I think it comes out to exactly 1000 points. Let me know if I need to change anything. I tried to focus more on the personalty and sticking with the 7 deadly sins theme for each of the 7 brothers. In addition I tried to find Greek names that bet fit their personality. I was going to use Roman names but the Greek ones sounded better.
EDIT: I wrote this stuff up before I saw your
map. I am not sure if you want them to own the coliseum and amphitheater on the map or have them add their own private versions of it. In short I hope they get to keep the stuff I wrote about since it really fits their "7 deadly sins" personalities.
