What's the point with that quite lackluster story in Endwalker?

I think most people agree with that though. It’s why a few people here were confused when someone saw the ancients as choosing when to die and returning to the lifestream as something bad, when in reality they were basically immortal and if they didn’t do that overpopulation would be a major problem.

Exactly over population, death is natures way of controling a species population. Thats why I said death is needed..life and death keep each other in check.
