House Blackfyre

House Blackfyre is a cadet branch of House Targaryen, founded by Daemon Blackfyre, a legitimized Great Bastard of King Aegon IV Targaryen. House Blackfyre is named for the Valyrian steel sword of the same name.
Their sigil is a black three-headed dragon, breathing black fire on red, the Targaryen sigil with the colors reversed. Their motto is "Blood and Fire," the reverse of House Targaryen's. Among the traits passed on to the Blackfyres by the Targaryens were platinum blond hair, violet eyes and the premonition-like dragon dream ability.
