I've never seen the Draconian Law trait! What is it and how do you get it? I love seeing different vices/virtues.
It's from the "Switf Justice" line of traits.
It's a huge bonus on dread with a ten penalty on happyness (Of course, the dread offsets the penalty. You get it by routinedly executing everyone. This means lots of mass executions. I seldom get beyond "Tough Justice". If you keep executing people after that, you get "Secret Random Justice".

Right now I´m enslaving everyone playing as the Almoravids and haven't gotten even one of that line's traits through, so I guess it´s a bit random.

Speaking about traits: how do I get the "Leads from the front" line of traits, and/or the other battle-related bonuses? Throwing my general into the fringe does not seem to help.
