Thes are the twin princesses Dawn and Eve, as you can tell by their clothing, hair and eye colors. Eve aways says things darkly, and Dawn warmly, but they are both super energetic. Dawn's talent is to tell anything about any living creature, and that is why she is holding a bird. Eve's talent is to tell anything about any inanimate object like a brush, so that is why she is holding a comb. They are two characters from Piers Anthony's Xanth series.
