Lǎo Fáng (老防)
(I'm not sure if this set in actual China, and if it is in what era, so I'll leave all geographic terms out of my bio)
Fang is the second oldest of four children. His parents were horselords and horse breeders in the frigid northwest plateaus, but Fang received a ministerial education farther to the south and east, in a much larger city. One evening, when Fang was still a teenager, he was riding his horse outside of the city when the beast was spooked and he was thrown off the saddle. The fall itself would have been only minor, but he had been riding at some altitude and slid down a steep slope for several hundred yards until he came to the bottom.
A day later he was discovered, broken and dehydrated and brought back to the city. Thankfully for him, his horse had wandered back to the city alone, arousing concerns for Lao Fang's health. His legs were broken in several places, and he was dotted with bloody wounds from the fall. These would fade with time though, and even his legs would heal, although he would be permanently hobbled with a limp, caused by an irregularly healed ligament in his left knee.
When his education was finished, his academic and ministerial aptitude had become the notice of the emperor, and went to work in the imperial city. Soon, he had earned the respect of Emperor Tai.
He is known for his cool head, a dark humor, and a crooked but charming smile.
Oh, Neko, if I may offer one slight suggestion? The Emperors of old China would take an imperial name when they were crowned. For example, the last Emperor of the Han dynasty was named Liu Xie, but he was called Emperor Xian during his reign. To his closest vassals he would still be Xie, but to his 'people' he was Emperor Xian. Sort of like what the popes do.
