Ever since she was a child she was seen as "below others" "weird" and a "freak". The feral forms of low class Avium are far more dangerous than their higher counterparts. Having elongated claws and fangs, and sometimes strength beyond their normal.
Ceres was often picked at for her looks, having other children pluck her beautiful feathers.

One day she couldn't take it and attacked a middle class boy. While she got some injuries, his were far more severe.

Now people just stare at her.
