While keeping his main camp at Avarga on the Kherlen River, he decided to create a closed territory as the homeland of the Mongol tribe at the headwaters of the Onon, Kherlen, and Tuul Rivers around the holy mountain Burkhan Khaldun, where he found refuge from the Merkid. “Let no one set up camp at the source of the Three Rivers,” he commanded. With that order, the Mongol homeland was closed to all outsiders except for the Mongol royal family, who buried their dead there for the next two centuries and who returned there for familial ceremonies and closed family meetings without outsiders.
