Murong Xi
In summer 407, after Murong Xi's empress Empress Fu Xunying died, Empress Dowager Duan, for reasons unknown, removed her own empress dowager title and moved out of the palace. That was the last historical reference to her, and it is not known what happened to her after Murong Xi was killed in a coup by his adoptive nephew Murong Yun (Emperor Huiyi) later that year.
