It is right after this constitution is adopted that napoleon sends le clerk over to san doming on his secret mission to basically over n everything in it. And the one thing that can't happen, cause it will completely ruin the whole plan, is if it gets out that his job is to reinstate slavery. He's no angel, by the way, but nobody that comes to power in a war of racial exterminations going to be angelic. But he will be outmanoeuvred by even friendly allies. Will essentially create a cast system based on racial make up again,. Or they revolt.
