hmm... just my opinion, but a short skirt doesn't really seem fitting for Schala... Schala struck me as a very refined young woman... (basicly, the type of girl Marle wasn't, but should have been.) The dagger I can see though. A lot of women, especially of high status, carried daggers for self defense in the middle ages--not that 12000BC is "middle" ages... but... seems fine.
(A lot of people don't know that... also some men would carry around several daggers of valuable material, for chance encounters with a woman that might need wooing... as gifts. It was sort of a gift for women men could carry around without losing face... as opposed to things like flowers and jewelry... also they were slightly less likely to be stolen...)
Rambling aside, I wouldn't mind playing Schala myself... but... idunno... that skirt just kind of... makes Schala look kind of whorish to me...doesn't bother me as much on Lucca... but then I don't use her much and she is far from refined...
