You are connected to one of the dragonmarked houses, but you haven't (yet) manifested a dragonmark. You might be a member of the family by birth or an employee of the house with no familial connection. You've earned your living by doing the business of the house, serving as the hands, feet, and eyes of house leadership in the world. You might have many old friends, mentors, and rivals in the house you serve, plus allies or enemies in other houses.
