Vyper is tiny and small boned, and weakly built, but endowed with a spectacularly and bulgingly overfleshed showgirl's figure, sporting huge, wobbling H cups and a narrow, usually corsetted waist, with wide, swivelling hips that wiggle as she walks, with a jutting bubble butt atop tapering legs.  Her complexion is pallid, her eyes dark, her hair raven.  She is attractive in a fleshily, pillowy, bulgingly quivering kind of way. (unmodified initial CHA of 14).  She appears to be 18 years old.  She never goes out without goth makeup.  She speaks common with the accents of Waterdeep's docksides, laced with street slang.  Her demeanor is dark, hooded, with a schoolgirl's mien hiding under a thin veneer of restraint curbing ... who knows what?  She is dressed as a street shill for a pickpocket gang, risquely and revealingly cut to display  charms meant to distract marks from noticing their purses being lifted.
