Over 8,000 years ago, the Daos civilization flourished in Southern China. The Daos Empire consisted in three tribes: Dai, Shura (ancestors of today's humanity) and Gorma who lived harmonously. However, one day the Gorma Tribe tried to take over the Empire. Thus began the war between the Gorma and the Dai Tribe. The battle continued for 5,000 years, led by the Gorma Triumvirate. (imdb)
