Song Jia

Also known as Demon Saintess Jia is so-called because prior to the catastrophe with Di Ji her story was considered the defining shame of the recent generation. She formed a Good Fortune Core, a rare core with a connate association with worldly good fortune and feng shui. 
She was engaged to Shu Bao of the Shu clan. She later came to the Shu Pavilion which was the sect both belonged to, to complain that he mistreated her and gave away her purity in a lost gamble to a disciple from the Jade Gate Court.

She is considered by the community to have some connection to Jia Ying or Senior Ying. Possibly using one or both of those names as alternate personas.
