Ambroise St-Bierr is the Daimyo of House Gaijin. He's held onto the position for most of the past century, a strong voice advocating for social reforms, making him somewhat of a black sheep among the First House.
Whatever his positions and beliefs might be, or what others might think of them, he is Daimyo and his decisions are final and unforgiving. He expects the men and women of his House to be beyond reproach. It is this authoritarian stance that has kept would-be challengers in check, for the time being, but the Daimyo might soon prove too bold for the Clan to ignore.
