Here is another official illustration I’ve provided for "The Rise Of The Dragon: An Illustrated History of the Targaryen Dynasty, Volume One" by George R. R. Martin, Elio M. García Jr. and Linda Antonsson.

"...
Meanwhile, Prince Daemon Targaryen himself hastened south on the wings of his dragon, Caraxes. Flying above the western shore of the Gods Eye, well away from Ser Criston’s line of march, he evaded the enemy host, crossed the Blackwater, then turned east, following the river downstream to King’s Landing. And on Dragonstone, Rhaenyra Targaryen donned a suit of gleaming black scale, mounted Syrax, and took flight as a rainstorm lashed the waters of Blackwater Bay. High above the city the queen and her prince consort came together, circling over Aegon’s High Hill.

The sight of them incited terror in the streets of the city below, for the smallfolk were not slow to realize that the attack they had dreaded was at last at hand. Prince Aemond and Ser Criston had denuded King’s Landing of defenders when they set forth to retake Harrenhal . . . and the Kinslayer had taken Vhagar, that fearsome beast, leaving only Dreamfyre and a handful of half-grown hatchlings to oppose the queen’s dragons.

The young dragons had never been ridden, and Dreamfyre’s rider, Queen Helaena, was a broken woman; the city had as well been dragonless. Thousands of smallfolk streamed out the city gates, carrying their children and worldly possessions on their backs, to seek safety in the countryside. Others dug pits and tunnels under their hovels, dark dank holes where they hoped to hide whilst the city burned."
