Murong Sheng
However, due to pleas from Princess Lan and Lady Yi, Lan Han did not execute Murong Sheng. Later that year, Murong Sheng overthrew Lan Han in a coup and restored Later Yan as its emperor. He considered executing Princess Lan, as the daughter of a traitor, but Consort Ding (then an empress dowager) interceded on her behalf, reasoning that Princess Lan was the one who protected both Murong Sheng and herself, and Princess Lan was spared. However, she would never be empress. Murong Sheng never created another person as empress during his reign, either, suggesting that he still considered Princess Lan as his wife. Murong Sheng was assassinated in 401, and no further historical reference was made to Princess Lan after that point.
