Like the Ha Family, the Yeon Family is a thoroughly matriarchal family, so males cannot take central roles in either the main house or the branch house of the Family. Thanks to this, the females of the Yeon Family, especially those of the main house, have a tendency to look down on men. The Yeon Family is famous for producing powerful Flame users. It is said that members of the family are "flame" itself from the moment they are born.
