If you get the characters right you've done sometimes nearly half the work. I sometimes find I get the characters right then the characters will often help me write the book - not what they look like that's not very important - what people look like is not about their character. You have to describe the shape they leave in the world, how they react to things, what effect they have on people and you do that by telling their story.
Terry PratchettSome humans would do anything to see if it was possible to do it. If you put a large switch in some cave somewhere, with a sign on it saying 'End-of-the-World Switch. PLEASE DO NOT TOUCH,' the paint wouldn't even have time to dry.
Terry PratchettWho knew what evil lurked in the hearts of men? A copper, that's who. (...)You saw how close men lived to the beast. You realized that people like Carcer were not mad. They were incredibily sane. They were simply men without a shield. They'd looked at the world and realized that all the rules didn't have to apply to them, not if they didn't want them to. They weren't fooled by all the little stories. They shook hands with the beast.
