Given her (and her family's) twin occupations (trapping and banditry) it would follow that Tsira is likely a Chreotha, although this is never overtly stated. If this is the case, it may be that we can identify the House Colors of Chreotha from the Red and Yellow beads on her Darrskin boots? This may be making a lot from way too little evidence, but that's why it's called speculation.
