Gu Tianqing

Gu Tianqing had a secret relationship with Rong Yan and plotted against Gu Xijiu causing the original Gu Xijiu to commit suicide. After 'failing' to plot against Gu Xijiu she was exposed and imprisoned. Emporer Luo originally intended to just banish her and not let her marry anyone influential but after Di Fuyi demanded her death she was executed.
