There's... kind of an airbender shortage in Republic City. There aren't enough of them around to have one for every team that's out there. [ Also the shortage is in the entire world. Because wholesale slaughters almost 200 years ago. But he's definitely really pretty sure that's not his story to tell, probably. ] I guess there would be ways to adapt the rules to include them if we got enough here. Even if it's hard to figure out how you call fouls on something that you pretty much can't see being used.
