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

Personally I still think the Sundering was straight up genocide. It makes zero sense for the different races all to evolve exactly the same on all the shards.

The existence of Ardbert (and his party), Grenoldt and Mowen on the first is meant to imply that everyone and everything on each shard split identically across all the shards. This is, of course, somewhat muddled by the fact that our WOL can be anything we want, but the Warriors were all identical reflections of the Derplander's squad, Grenoldt is just Gerolt with hair, and Mowen is just straight up Rowena with one letter missing and one changed. Of course, this bears the question of free will and why and how there's been no variation on interbreeding and intermixing over the past 12,000 years. Did every person marry/have children with the exact reflections of their spouses on other worlds? Have there been no other stories like Lamitt falling in love with Ardbert? Have there been no other mixed children like Hilda? Or do genes eventually "settle" on one species, like with G'raha?

I also think Venats "fly my childrenand never look back" in the moon ship plan was doomed to fail from the start. The moment that ship left the fading protection of Zodiarks influence, they would all have started turning, trapped like rats with no escape.

Playing devil's advocate here, but I think the implication was that the Song of Oblivion spreads from star to star. We're never told how much time passed between Meteion's escape from Elpis, but it was at least months or years. It's also likely that the Loporritz had scouted stars that were unlikely to have been affected by the Song yet, although they make it clear several times that they actually have no idea what's on them or what they're like.

The goal of the Moon plan was simply to outrun the Song for as long as possible. In the face of death, sometimes all you can do is struggle to live just one more day and hope that maybe one day, someone will find a way out of this.
