Posting this for blu since he doesn't know how to use the interwebs 100% yet:
An Osmanli fighting noble (Ottoman Empire) who left during the modernization of the Ottoman Empire. Caught up in the elation of the time in Turkey, he finally admitted that though promising, the Ottoman Empire was doomed, having traveled and seen what the rest of the world powers were up to. He left his country quietly in the night, though not without a promise to his Grand Vizier, a long time friend. He would send back what information he could. It was his information and connections that later brought the Ottoman Air Force into being in 1909, after arranging for 2 Turkish pilots to attend the Internation Aviation Conference in Paris.
Khan lead the Akiunci (frontline cavalry), and later the Sipahi (elite cavalry). He lead decisivly these forces, who could at once attack as well as defend, attack brashly and then melt away quickly. Of course the Ottoman Empire was the first military force to employ the musket (smoothbore long guns), and to this day still make the best firearms.
Not much else is known of Khan. He must fight publicly, but all else he keeps private. It is assumed that his connections range far and wide, and in many places, high as well. An inscription seen on his gear translates "Ever victorious".
