Elana looks just like the people of Andrecia?

False. In context, Elana does not look enough like the natives of Andrecia to be mistaken for one of them.

Incidentally, though the story makes clear that Elana does not resemble the natives of Andrecia closely enough to be mistaken for one of them, the covers of the Collier, Troll, and British editions show her as racially identical! (Authors do not choose a book's art work and often don't even see it prior to its publication--although I did get an advance look at the beautiful covers of the Walker and Bloomsbury edition Bloombury editions.)
