Cella: society princess likely mixed up in some dangerous criminal play she's unaware of
Shireen: tiny, sheltered heiress who solves all the crimes she reads about in the paper but rarely is permitted to leave the house
Missandei: something like a playwright or translator, likely mixed up with those same noble criminals
Ros: possibly a nightclub singer or hostess or some such, more likely a high-end pinup model/call girl who hears all the politicians' and powerful men's secrets
Lyanna: brazen and tough, a little rich girl lost with dreams of something more
Arianne: possibly a starlet with connections to the underworld or possibly just a heiress of the underworld, clever and conniving and oddly compassionate

Arianne: a vivacious rich girl with a nose for politics and business, not afraid to go after what she wants
