Morannon appears to have no soul.  She doesn’t seem to care for the children or Drako.

She’s always unhappy.  She’s just going through the motions so basically is a zombie (inside).

Vincent, as you can see, is now school age.  Morannon was waiting for Lazaria to grow up but she got fed up and left.  Drako took over.

Drako’s not happy either as he can’t get close to Morannon and yet there’s no-one else who can give him the happiness he craves.
