Sozin: With Roku gone and the Great Comet returning, the timing was perfect to change the world. I knew the next Avatar would be born an Air Nomad so I wiped out the Air Temples, but somehow the new Avatar eluded me. I wasted the remainder of my life searching in vain. I know he's hiding out there somewhere; the Fire Nation's greatest threat, the last Airbender.
