The Sage Lands.
It was the name of the multi-layered Immortal World above all realms. It was mostly dominated by beasts and Celestials but Immortals thrived there.
No one knew the ancient times as no history was recorded beyond a certain point. At least several million years had passed before humans, demons, and other races began to take up their own space in the various layers.
Rising up was not easy. While some connections via ascension pools existed, there were barriers that had to be overcome by tribulation first. Even if a power from a higher layer wanted to extract a lower realm cultivator, if they had not crossed the tribulation, they would be prevented.
It humbled clans and those that believed they were destined to have the world bow to them, found themselves only able to reach the next step if they overcame the tribulation. Heaven and Earth were fair but something prevented any shortcuts.
