One for fellow England supporters in the current rugby World Cup… (For the record, I think we’ve been lucky, and that the South Africans will win. I’d love England to prove me wrong, but can’t see it)
Our knowledge flows through you Aang... So officially they covered 7 or 8 avatars. The four avatars before Aang, the first Avatar, and 2 or 3 random ones. An interesting series I wouldn't mind watching would be the second Avatar. The first Avatar sought out the four elements and the subsequent Avatars had tradition and history behind them. The second Avatar would just be really confused person though once he or she mastered talking to the first Avatar, the show would play out almost like a Buddy Cop story or mentor/cub story.
