Zhao Ming
Zhao Ming, also known as the Iron Dragon, is one of the two legendary lords for Cathay in Total War: Warhammer 3 and one of the first playable Cathayan characters in any Warhammer setting.
Zhao is the son of the Dragon Emperor and Moon Empress. While his parents chill above Wei-Jin, Zhao runs the Western Provinces of Cathay from the city of Shang-Yang, which borders the Mountains of Mourn and as such has to deal with incursions of Skaven and Ogres. However, being on the entry-point to Cathay he also sees the travellers and traders that make it from the west, with permanent embassies from the Empire, Estalia and Tilea.
Zhao Ming holds great skill in alchemy and likes to integrate it into his armies. He welcomes mages of all kinds, which causes his siblings to worry about his mental stability due to his proximity to the Great Maw, especially when he comes under a moment of eccentricity. This eccentricity is actually treating the people he leads as actual human beings with value and not simply viewing himself as above them unlike the rest of his family, so take it with a grain of salt. He is not exactly on good terms with his older sister Miao Ying, and is often offended by her aloofness when they and their other two siblings meet.
He also turns out to be a bit of a mamas boy, and is the Moon Empress' favourite child.
This is all we know about him so far, but we'll learn more over the weeks to come.
