Yeah. All the airbenders are there. When the Hundred Year War began, the Fire Nation knew that the next Avatar would be an Air Nomad, so they exterminated every airbender. My father, Avatar Aang, managed to get away and spent 100 years frozen in a piece of iceberg. When he woke up, he began a journey to master the other three elemens. He, my mother and their friends ended the war, but dad was still the last airbender. At least, until my brother Tenzin was born.
[And then he became dad's center of attention but that's another story.]
After the Harmonic Convergence passed and Korra opened the spirit portals, new airbenders started to show up. My brother, Bumi, who wasn't a bender, was suddenly able to airbend out of nowhere. Now we are all helping to rebuild their nation and Tenzin is teaching them all about Air Nomad culture.
