Arrax was a dragon, apparently male, ridden by Prince Lucerys Velaryon during the reign of Viserys I Targaryen and at the Dance of the Dragons.
Although he grew larger every year and was big enough to be ridden, Arrax was still young at the time of the Dance of the Dragons.
According to Archmaester Gyldayn, he was faster, but also five times smaller than Vhagar. He would be pearly white with golden chest and eyes, and his flames would be yellow.
HistoryWhile Prince Lucerys Velaryon is still in the cradle, he receives a dragon egg by royal decree from his grandfather, Viserys I Targaryen.
The paternity of Rhaenyra Targaryen's sons being questioned by her political opponents, rumors are circulating that the eggs given to her sons will not hatch.
The birth of Arrax belies them. Lucerys becomes a dragonrider before the start of the Dance of the Dragons.
In the year 129, as the war approaches, Lucerys is sent on his dragon as a messenger to Accalmie.
The Dark Council believes that Lord Borros Baratheon, overlord of the Stormlands, will favor Queen Rhaenyra Targaryen's side, but the Prince of Peyredragon Jacaerys Velaryon is convinced that the presence of a dragon will help the nobles make a decision.
Lucerys and Arrax manage to outrun a storm approaching Accalmie, but when they arrive, they discover that they have been preceded by Prince Aemond Targaryen, brother of the pretender Aegon II Targaryen and dragon rider of the terrible dragoness Vhagar.
The latter roars at their approach, which would have shaken the walls of Accalmie and made Arrax tremble. Lucerys is forced to use her whip to force her dragon to land in the castle courtyard.
After some heated exchanges, Lucerys leaves Accalmie empty-handed and in the pouring rain. Still young, Arrax struggles to stay airborne in the middle of the storm. He is caught by Aemond, mounted on Vhagar.
Above the Bay of Shipwreckers, and in the middle of the storm, Arrax is shot down by the older and more massive dragoness. Three days later, Arrax's head and neck are washed up at the foot of the cliffs of Accalmie, where they are devoured by crabs and gulls.
