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

[Rulakir]

It's a head scratcher for sure. I must admit, I raised an eyebrow when it was revealed that Venat played a large part in the existence of the Rejoinings as they were often cited by some as an 'unforgivable' act that could not possibly be excused in any way, shape or form.

I do wonder if that stance will soften now that Venat is ultimately the one responsible for their existence...

I've said I didn't think Venat cared about the shards and that she created more than necessary as fodder for the Ascians, but to have that essentially confirmed? I'm still coming to terms with it myself because that was my most pessimistic view of her. He says we're not supposed to view her as a villain, but how could you not? She escalated from being the antagonist of the Ancients to all life on the reflections as well.

Edit: I forgot to mention that Yoshi-P also indicated that Hydaelyn wasn't sundered, only Zodiark, so I've no idea what's going on with that dialog from the Watcher on the moon.
