Xing Emperor

The emperor of Xing is the father of both Ling Yao and Mei Chan as well as eighteen other royal scions. As Emperor, he is sent a concubine from each of the 50 families that make up the nation in order to bear a child. He is rumored to be of failing health, prompting both Ling and Mei to venture to Amestris in order to find the secret to immortality so as to raise the standing of their respective clans.
