Horse Plague at the North Borders (X)

Originally, the three tribes of the North borders were composed of many tribes, and they lived scattered across the land according to their tribe. Their livelihood included raising herds of horses near the river banks. There were competitions and fighting within the tribes. Later, one tribe rose up with the support from the last Emperor of the Xia Dynasty and it spent more than 10 years unifying the powers of the big tribes in the North borders. 

This mighty tribe is the "Qiang tribe". It is said to be the last descendants of the Qiangwu tribe. Moreover, it is now the most powerful, largest in number, and the richest tribe amongst the three tribes of the North borders. The royal family of the north borders operates differently from that of the central plains. The governing authorities are complicated and confusing.
