Total War Warhammer III's Grand Cathay faction has been revealed | OC3D News (overclock3d.net)
 
Warhammer Fantasy fans may already know about Grand Cathay, the little-known faction that has barely been spoken about since Warhammer Fantasy 2nd Edition. Until now, practically nothing was known about the far eastern faction, as its lore was made up of little aside from minor decades-old references.

As part of Total War Warhammer III's development, Creative Assembly and Games Workshop have worked hard to flash out these lesser-known factions with full armies, plenty of lore and some much-needed background details. Like Kislev, Grand Cathay is being taken to the forefront of the Warhammer Fantasy work with Total War Warhammer III, expanding the setting with fully fleshed out factions and armies. 
 
Leading the empire of Grand Cathay is the celestial Dragon Emperor, a being that is frankly too powerful to be included in Total War Warhammer III, much like to Chaos Gods, Nurgle, Khorne, Tzeentch, and Slaanesh. Thankfully, the Celestial Dragon Emperor and his wife, the Moon Empress, rule from the Celestial City and rarely travel to the surface world. Cathay's legendary lords will be the Dragon Emperor's children, dragons that can take humans' form. 

Cathay’s playable legendary lords are Zhao Ming, the Iron Dragon, ruler of the Western Provinces and Lord of Shang-Yang, and Miao Ying, the Storm Dragon, ruler of the Northern Provinces and Commander of the Great Bastion. Miao Ying is featured in the trailer below. 

Grand Cathay's armies are designed to be defensive, offering players powerful ranged units and strong infantry. Giant Terracotta Sentinels, powerful living statues, will act as one of the faction's most powerful land-based units, and flying machines can be used to take battles into the air. The faction also has access to dragon-blooded sorcerers who can wield the lores of Yin and Yang to combat their foes. 
 
Total War Warhammer III is being used to expand the Total War Fantasy universe by fleshing out the far off factions that have been ignored for far too long. Grand Cathay will look and play unlike all other factions in Total War Warhammer III, giving fans of the franchise ever more variety, especially in the game's planned globe-spanning Mortal Empires map. 

Total War Warhammer III was delayed yesterday until early 2022, giving Creative Assembly the time needed to polish their game and create a game that lives up to the expectations of long-time Total War fans and Warhammer fans alike. We expect to see Grand Cathay's armies in action soon on Creative Assembly's Total War YouTube channel. 
 
The faction sounds interesting to me.
