As I understood everything, we were doing more or less the same kind of atmosphere as TLA ... but with one character time-displaced to explain why this universe came to exist in the first place.  And because Karma wanted to play Asami.<br/><br/>But I wouldn't expect to see steam-cars or all that stuff, running around.  Maybe slightly modified versions of the war-balloons, but even those would be redundant without a real war to be fought.  The city she's having built would just be in the infant stages... just a major construction project where workers (probably prisoners) are sent to create a city worth her new unified world.<br/><br/>I don't remember why we'd written off the guy from the Air Temple as a possible inventor, but Azula couldn't use Sokka because he's with Zuko.
