The idea, freedom, Indomitability air, air nomads displayed in drafts.
Aang, the center stage is the last airbender, the person that all of the people come together, giving all his power, converging on him the strength of the winds. The sense of balance and time of complete chaos in representing air, Indomitability and purity.
Describe this work is impossible, perhaps because like drafts, you feel all your spirit but you can never describe.
Simply, all the power of the elements of the room together in the last person able to conjure his presence, to control, to hear the voice of the air.
Save all the secrets of a culture that has disappeared, living with all its glory in the past for their children, the last airbender, Avatar Aang.
