Describe how the first group looks in The Magician's Nephew.
I think you need to expand your question to be far more specific - the first group of what? I can only infer that you are talking about the group of statues that Polly and Digory come across in the Deplorable World. Note that Digory says of them "They were nice people, I think", and the narrator seems to confirm his opinion:
All the faces they could see were certainly nice. Both the men and women looked kind and wise, and they seemed to come of a handsome race.
But of course, in spite of these first few promising kings and queens, as we read on we discover the rest gradually become more and more stern and then finally downright evil. It is from this line of kings and queens that Jardis the white witch comes from, and it is this character that Digory and Polly unwittingly awake.
