Vaan is the main male protagonist and a 17-year-old orphaned male Hume street urchin who lost his parents in a plague when he was 12 years old. His only brother, Reks, died two years prior to the start of the game, during the Archadian Invasion of Dalmasca. He makes a living as Migelo's assistant, running various errands for him, while at the same time pickpocketing from Archadian soldiers while claiming to take back what is Dalmasca's. He is a cheerful and energetic boy, and among his friends he is considered their leader. Vaan dreams of someday becoming a sky pirate in command of his own airship. He trains to meet this goal by killing dire rats in the sewers of Rabanastre on a daily basis, for which Dalan gave him the nickname "Vaan Ratsbane".
During the events of Revenant Wings, Vaan becomes captain of the Airship Galbana and uses it to travel to Lemures, meeting old friends while making new ones. The fact he was given the title of the "leading man" by Balthier, suggests a teacher/student relationship between them by the others. Vaan also gains the Godblade Anastasia from the Yarhi. In the aftermath, Vaan and Penelo take their leave from Rabanastre to have their own adventure.
