Fire & Blood

House Targaryen sigil is a three-headed dragon breathing flames, red on black. The three-headed dragon represents Aegon the Conqueror and his two sisters, Rhaenys and Visenya,[2][3] Their house words are "Fire and Blood."[4] Although the Targaryen kings took their seat at King's Landing, the place where Aegon and his army first landed in Westeros and made their first fort, Dragonstone remained the traditional seat of the heir-apparent to the throne.

House Targaryen historically followed the gods of Valyria. Sometime before the conquest of the Seven Kingdoms, the Targaryens abandoned the Valyrian gods and converted to the Faith of the Seven, the predominant religion in Westeros. However, they continued to follow the Valyrian practice of incestuous marriage, wedding brother to sister, cousin to cousin, and uncle to niece, holding themselves apart from and above the noble Westerosi families.

The phrase "blood of the dragon" refers to what are considered typical Targaryen features: silvery-gold (or platinum) hair and violet eyes. Some Targaryens also have a high tolerance of heat, though they are by no means immune to fire. Another trait typical to Targaryens, and one that was passed on to the cadet house, House Blackfyre, was the ability to have premonition-like dreams.[5] Aenar Targaryen was a noble in Valyria before the Doom, whose maiden daughter had his visions written down and published in a book called Signs and Portents.

Probably due to their incestuous practices, the Targaryens are prone to madness; King Jaehaerys II said that with the birth of a new Targaryen the gods tossed a coin to decide whether the child would be great or mad
