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

I think the Thirteenth is the only shard worth visiting at this point. They could contrive a similar reason why we can only visit parts of it. The Void been part of the lore for far longer than any other shard. It would serve as a good balance to the First. I would feel happy and I think the world would feel reasonably complete if we went there and didn't bother to visit the other remaining shards.

We have actually been to the Thirteenth, though.

That's what the World of Darkness raid is. Maybe there is more of it to see, but we've definitely seen part of it.
