Something about the new Ascian lore

[Daralii]

Then as far as summoners go the dialog mentions multiple people in the form of "they". Then you have the cave mural paintings.

We could take the theory that the life force was in account, but not the souls. Let's say since the Ancients can see souls that people who had given up their life force - may have given them the idea to sacrifice the mortal life force to bring their loved ones back? I mean it's an interesting trait that the Ancients can see the soul - so for those that lived for eternity may have been able to see a soul transcend after the lifeforce is gone?

It's apparently a pretty simple process to see the color of someone's soul, to the point that it's just part of one of the Alchemist storylines. Ancients can obviously see it without the need of alchemy and can probably better distinguish the hue, but it shouldn't be any more complex than Y'shtola's eyes after she used Flow the first time.

The ALC questline in question was about seeing the colour of someone's aether, which I've always assumed to be relevant to the colour of someone's soul before, but with the new information about souls and Ancients I'm less sure now.

Also it was done through what was apparently the aether version of Luminol, so I'm not entirely certain if it's the "true colour" or if it's the colour as indicated by that specific alchemical concoction.

But Y'shtola does prove that it is very possible to recognize individuals through their aether as seen through aether-sight, as well as how aether shenanigans could make someone's aether unrecognizable.

Worth mentioning some Amroo can see a person's soul which is why Seto mistook us for Ardbert when we first met him.

Also Odin, or more precisely Zantetsuken. I haven't finished Eureka, so I don't know the full details of that.

Odin is a kind of special case which is explained in Eureka so I probably shouldn't spoil it for you. Needless to say, in his case the original Warrior Odin's thoughtform probably defined what the Dark Divinity ended up being like.

I imagine all the Feyfolk can, since Feo Ul talked about our "beautiful soul" being in tatters after absorbing the Light from Innocence.
