Apologies. Integral was a poorly chosen word, I meant to say a unique aspect of the series. I've RPed multiple NPCs before, that's not a problem, but I'm not looking to oversaturate the RP. The last thing I want to do is go against whatever you have planned. I'd like my character to have something to do with pro-bending though...would it be okay if he was retired former champ and now a trainer?
