FFXIV Endwalker MSQ 64-Travelers at the Crossroads

Why Hythlo? Why? Seriously lol. The landshark kills me.

So Venat's magic is on us. This traveler's ward seems to be what we call the blessing of light. Lore-wise it was always the echo that protected us from tempering. So that is a little confusing but the blessing of light has also always been some sort of protection against the ascians and primals as well. But we know the echo wasn't given by Venat it is just something we have from being an ancient soul that was awoken from the vision. We know its a way to communicate with her. So what is the significance of the crystals of light then? Those supposedly held the blessing. And we have six of them. This is where it is a bit confusing lore-wise. I have every intention in going back to sort through all the information the game has provided on this. But that is a ways away.
