Aveline can don three separate and very different guises: that of a lady, a slave, or an assassin. Aveline retains the higher-class privileges of her French father’s status; this combined with traits inherited from her African mother allow her to fluidly slip between social strata.

I mean, in principle, this is a great idea for a game mechanic -- having to consciously, tactically manage different class identities in order to achieve set goals could present an interesting, useful challenge, especially for gamers who are not accustomed to thinking along those lines.

But I'm not sure it's going to work out quite that way in this case. I mean, aside from skin color, what "traits inherited from her African mother" allow her to "fluidly slip" into the slave "social stratum"? ::sigh::
