A Clash of Kings
Magister Illyrio Mopatis sends Saduleon, Joso's Prank, and Summer Sun to Qarth, to bring Queen Daenerys Targaryen back to Pentos in preparation for her return to Westeros. Daenerys accepts, but insists on renaming the ships as Balerion, Meraxes, and Vhagar, in homage of the three dragons of Aegon the Conqueror.
A Storm of Swords
Daenerys Targaryen travels aboard the Balerion with her khalasar, her handmaids Irri and Jhiqui, and her three young dragons, Drogon, Viserion, and Rhaegal. While enroute in the Summer Sea from Qarth to Pentos, Ser Jorah Mormont convinces Daenerys to change course for Astapor, buy an army of Unsullied, and continue to Pentos overland.
I will never see her like again.
