Red Feathers are a group of 6 families within the 12 Founding Families who are able to use their own "Unique Dragon's Gate" giving them unique supernatural powers. Those 6 families have 36 branch families which means over the generations the powers occasionally got watered down into new powers giving them a Dragon Gate that is different from the Main Family.
Anyone that has any special powers granted to them by a unique Dragon's Gate are referred to as Red Feathers.
