Khangzhan Stories

My first book, set in a high fantasy universe watched over by a powerful and ancient society known as the Kangzhan, who's lives are extended magically to allow them to train for longer and achieve mastery in their chosen discipline. I have a whole universe planned out but I didn't know where to start so I just picked a point at random. This takes place a few thousand years, a short amount of time for the Kangzhan, after a war called the Grand Purge where they took heavy losses. It follows the story of one of the most senior members of the Kangzhan seeking to get back in touch with an allied race, the Arokraka, who hid after suffering sever defeat in the Grand Purge.
