Well, 'old emperors neverending story' might imply that there are so many aspects of the lives of old emperors that seem to go on and on. For example, their dynasties had long histories. There were countless events like wars they waged, alliances they made, and the cultural influence they had. Their stories are like an unending tapestry of power, politics, and prestige. They had harems, court intrigues, and the building of grand palaces which all contribute to this seemingly never - ending story.
The story of Genghis Khan could be an example. His vast conquests, from Asia to Europe, created an empire that was huge. His military strategies are still studied today. Also, the mystery surrounding his death and the succession of his empire keep adding to the story. There are so many aspects to his story - his leadership style, the cultural exchange his empire brought about - that it feels like it has no end.
