Comments: The various romance subplots are all very well-written, and some of them are quite funny, I might add. All characters from both series are very well-written and in-character. Started before the finale of Avatar, so slightly not-canon compliant.
Shay Guy: ...Bending isn't genetic. Good if you can get past that, though.
Wo G material given on Avatar:TLA verse states that Bending is based mostly on the spirituality of the given society. Hence why Nomads were almost completely Benders as a society as compared to the other nations.
