We've seen the pictures and the videos and we've gotten hyped and that's great... But I believe that Aang can save-- sorry. I believe these dragons are chicken scratch to what's really waiting for us, and that is a dragon boss in the Vault of Glass. It makes sense, based on dragon lore: A massive dragon is asleep deep in a dark, dank dungeon, and heroes come through hell to get to it, in order to steal its even more massive hoard of loot. I think all these other dragons are merely loosely dispersed babies or descendants, and we probably won't fight them. They simply serve as a reminder that there's something crazy around the corner on 9/9....
