Gan Ning is based on the military general of Sun Quan during the end of the Han Dynasty of China. He was born in Linjiang in the Ba Prefecture and took the style name of Xingba. He gained the titles of General Who Oppresses the Enemy with Ferocity and Grand Administrator of Xiling during his military career.
Gan Ning was rough but forthright and head strong. He was open-minded, valorous and skilled in strategy. His lack of respect for material goods was balanced by his respect for talented men. Gan Ning was extravagant and often covered his traveling quarters in silk only to cut the cloth up when he left. He traveled surrounded by carriages and steeds or when by water, galleys or light ships. He hated wealth. Throughout his younger years, he paid no heed to chivalry and often committed murder, both in public and in secret.
