Rong Yan

Rong Yan had a secret relationship with Gu Tianqing and plotted against Gu Xijiu causing the original Gu Xijiu to commit suicide. After 'failing' to plot against Gu Xijiu he was exposed and imprisoned. Emporer Luo originally intended to just banish him and not let inherit any title but after Di Fuyi demanded his death he was executed.
