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

I don’t think they even say who made the Venat minion though. For Zodiark they could just chalk it off to it being one of the remaining sundered, or that it was found as an early concept in Amaurot. Easily done. We already have the little amaurotine minion that’s essentially a concept. It wouldn’t be very far fetched and it could at least go into some detail of him outright keeping the world safe.

Easily done, sure, but also easily not done. Like I said before, I don't think it's that big of a deal. It doesn't add or subtract to the story/worldbuilding, just nice to have, but also doesn't need to exist.
