Syrax was a dragon, apparently female, ridden by Rhaenyra Targaryen during the reign of Viserys I Targaryen and at the Dance of the Dragons. It is named after an ancient goddess of Valyria.
Syrax laid several clutches of eggs in her lifetime. Her scales were yellow.
By the time the Dance of the Dragons came around, she had long been used to chains and had grown fat from being overfed without hunting.
At the tender age of seven, in the year 104, Rhaenyra Targaryen rode Syrax for the first time. In 111, when her uncle Daemon Targaryen returned to King's Landing, Syrax and Caraxes often flew together to Peyredragon.
After the marriage of Laena Velaryon and Daemon Targaryen, Syrax laid several broods, probably between 117 and 118, after the couple returned to Lamarck.
In the year 126, Rhaenyra feeds Syrax with the corpse of ser Vaemond Velaryon, who had questioned the legitimate paternity of his first three sons.
Just before the beginning of the Dance of the Dragons, Syrax produces a new clutch: one of the eggs entrusted to the young Rhaena Targaryen, who goes to the Val d'Arryn, gives birth to Point du Jour, one of the last dragons.
