Haha, on a meta level I feel like it's similar? Kishimoto has said he adds technology that he wants when he feels like it's convenient and keeps out what wouldn't make any sense (like guns. Guns render ninjaing kind of pointless, like that scene in Indiana Jones |D) and aather is kind of similar -- we have technology but not a lot of it or anything too handy.

So basically there will be a few things she'll notice missing (TV?) and things she'll recognize (Peridot has radio communicators, right?); I think mostly I'll just have to pick and choose what she recognizes. (not tech, but earlier I made a judgement call to have her know what a vampire is, because they know what zombies are...)

Castmate that would make things Interesting for Jaina?
