Use of legendary or historical themes of Upper Asia begins with the legend of Ergenekon. This term refers to the mythical place that would be the place of origin of celestial Turks, located somewhere in the Khangai Mountains where the source of the Orkhon is. The legend resembles that of Romulus and Remus: the ancestor of the celestial Turks would be a child, the sole survivor of a group of proto-Turks, abandoned in this place of Ergenekon, allegedly collected and fed by a wolf. The "Turkish people" once reconstituted from this miraculous rebirth, there would have established a first civilization domesticated fire, discovered the art of forging. From this place of Ergenekon, celestial Turks would spread, based notably "empire of celestial Turks" who have controlled much of Inner Asia. Fire, iron, forging, wolves are the ingredients of the legend.
