I should have pmed you I guess. 

All good stuff. 

My character idea:
Air nomad, whose bison companion was killed some time ago. In despair, she isolated herself, and never returned to the monks. She has no tattoos, but still practices airbending, and lives by her own modified version of their monk beliefs. 

She's known to sell a lot of silk, and buy a lot of wine, and is looked on with pity by most air nomads.
