At the Event Horizon chat on March 18, 1999, GRRM gave the following answer:
The Seven Kingdoms usage of course dates from the time of Aegon the Conqueror. At that time, there was the King in the North (1), the King of Mountain and Vale (2), the King of the Rock (3), the King of the Reach (4), the Storm King (5), the King of the Iron Islands, who also ruled the riverlands (6), and the kingdom of Dorne, which was ruled by a prince (7).
Waters for King’s Landing and Dragonstone, Snow for the North, Pyke for the Iron Islands, Rivers for the Riverlands, Stone for the Vale, Hill for the Westerlands, Flowers for the Reach, Storm for the Stormlands and Sand for Dorne. Some believe that the bastard name for Targaryen bastards is Blackfyre, however it seems that Blackfyre instead was a name which Aegon IV’s bastard son Daemon was allowed to take. This is supported by the fact that Daemon Blackfyre’s half-brothers are named Aegor and Brynden Rivers, because their mothers were of the riverlands, and Princss Elaena Targaryen’s bastard children by Lord Oakenfist had the last name of Waters.
It’s possible that this picture is being complicated with A Dance with Dragons, as Lollys Stokeworth’s son is noted as “Tyrion Tanner”. There’s a possibility that this is another bastard name, perhaps unique to King’s Landing. However, the fact that Lollys conceived the child after being raped behind a tanner’s shop may make it likelier that this is a kind of mocking byname that the child has already been bestowed.
The nine Free Cities are Lys, Myr, Pentos, Braavos, Lorath, Norvos, Qohor, Volantis, Tyrosh. Of these all but Norvos and Qohor are located along coasts or upon islands.
GRRM has firmly stated that what happened with Daenerys at the end of A Game of Thrones was a unique event (SSL. EHC). That said, in A Dance with Dragons, it does seem that Daenerys has at least some supernatural protection from fire. While her hands are burned and blistered and her hair burned away, neither her scalp or any other part of her body was injured by her experience with Drogon’s fire.
The three great dragons of Aegon and his sisters were Balerion, Meraxes, and Vhagar. Aegon rode Balerion, Rhaenys rode Meraxes, and Visenya rode Vhagar.
Queen Alysanne, wife of Jaehaerys the Conciliator, rode a dragon named Silverwing. We are told that Balerion was killed some time in Jaehaerys’s reign.
Rhaenyra Targaryen rode the dragon Syrax during the Dance of the Dragons, while her half-brother Aemond rode Vhagar at that time.
Daenerys’s three dragons are Drogon, Rhaegal, and Viserion.
Legends of Serwyn of the Mirror Shield—a figure Martin says originates in from the distant past, but has been used repeatedly by contemporary singers—claim he defeated the dragon Urrax using his shield to distract it.
According to Tyrion and Haldon Halfmaester, Lomas Longstrider travelled the world and wrote to works, Wonders and Wonders Made by Man. He cataloged sixteen wonders in total, seven by the gods and nine made by man.
The only certain wonders appear to be the Valyrian stone roads, the fourth of the nine man-made wonders, (V: 117) and the triple walls of Qarth (V: 755). It may be implied in the text that the ruins of the Great Pyramid of Ghis, which we’re told Lomas Longstrider visited (V: 880), may also number among them. Speculatively, fans have considered the possibility of the Titan of Braavos, the Wall, the Hightower of Oldtown, and Harrenhal being among the other man-made wonders.
The natural wonders are not known, though readers have suggested that Casterly Rock and perhaps the Giant’s Lance might fit, as well as the Rhoyne, the Shadow, the Mother of Mountains, and the Fourteen Flames, among others.
