Cindy, If her title is to be a showgirl then perhaps her duties in the caravan should also include dancing. Also, it's impossible to be a showgirl without a group of showgirlS. However, her being a dancer would work perfectly;which would fall under 'caravan duties' as well. One last thing, please read the rules and put your password at the end of it. 

You might want to think about how people see your character. If her title is literally 'the concubine' no one will take her seriously, and as a dancer it could be detrimental to her career. It's one thing to BE a concubine, it's another to have that in your title.
