Undoubtedly, the Elf children born under the World Tree were almost all of the Longevity Species, with an average lifespan of about 830 years.
If there were breakthroughs on the Transcendent path, then 830 years would only be a beginning for most Elves.
In the depths of the Supreme Forest, even the youngest of the group of Elf elders was over 1500 years old.
Some of the older ones were even two to three thousand years old, approaching the theoretical age limit of the Elf Race.
Over six hundred years... Perhaps returning to the Supreme Forest, to their home, they might still see family members who had made breakthroughs enjoying peaceful years under the tree shades.
For the vast majority of ordinary Humans, it would have been the passing of dozens or even hundreds of generations, but for the Elves, though equally ancient, there was still a chance to treat it as if it were but a dream.
The 670 years of changes were simply too distant.
All they had known had become history.
