Following the Battle of Legnica in 1241, a captured Templar Knight was brought to the court of the Mongol prince Möngke. The young soldier taught the Templar ideals to Möngke and recruited the Mongol warlord into the Order. Some years later, Möngke inducted at least one of his children, Asutai, into the Order.
In 1251, Möngke became the Great Khan of the Mongol Empire, thanks to a prong of the Trident of Eden which was in his possession. Under Möngke's rule, the Imperial Guard, the Keshigs, were also for the most part recruited into the Templar Order. Thus, following his father's death after being killed by Assassin Zhang Zhi in 1259, Asutai recruited a skilled commander, Bayan, both as a Keshig and a member of the Templar Order.
