She is a child, a girl of perhaps eight or ten years of age.  At first look she seems European, but a second look, at her almond shaped eyes and olive complexion, leads one to think that her ancestry is probably of the Levant or Anatolia. She is a pretty girl, with dark hair and sparkling eyes.   She has a pleasant smile and she speaks English, though with an a accent that is not easily placed.
She has few possessions,  a wicker backpack, a bedroll bundle, a carved walking stick, a belt knife of the Moorish style and a necklace with a small bronze pendent.
