China is wracked by a terrible rebellion which now threatens the very capital. The provinces of You, Bing, and Ji remain loyal to the emperor, but outside of them loyalist bastions are few. Your own city of Wan is one of these.
The Loyalist Forces
The largest force loyal to the emperor lies north of the river, protecting the northern provinces.
The second largest loyal army is that of Luoyang itself, protecting the emperor and fending off two rebel armies.
The third largest loyal army is trapped in Chang An, unwilling to abandon the city to sally forth.
The fourth largest loyal "army" is the 10,000-strong ill-equipped garrison at Wan.
The Rebel Forces
The largest rebel army is the Dragon Army, currently blocked by the capital forces at Hu Lao Pass.
The third largest rebel army is the Tiger Army, currently blocked by the capital forces at Han Gu Pass. Tiger Army chose to bypass Chang An and race directly for the capital, but only managed to seize Tong Pass before being blocked at Han Gu. Now, Tiger Army is unable to bring its full strength to bear either at its front or in its rear.
The second largest rebel army is the new Phoenix Army, which is still mustering at Xiang Yang. Its eventual goal is to force its way up river and attack Luoyang from the south, breaking the current deadlock at the passes. You and your city are all that stand in the way.
