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

[KizuyaKatogami]

Because Emet-Selch "saved" him by accident. Nobody else would have been able to stop Gr'aha when he was going to sacrifice himself for the player. After that, it just became a manner of, "Okay now we have time to work on the problem, so let's just do the best we can."

It's not Gr'aha's fault that he cheated death.

But…it is. He could have just been content with 5.3, dying and watching the scions live on. Instead of moving on and forging ahead though, we instead shove his soul into our Graha. So much for dealing with loss…
