Does Elidibus actually think he can defeat the WoL?

If a Blade of Light were used on us, the WoL, and we were fragmented into pieces, it would be something completely new to the Blade of Light's toolset not previously mentioned.

Well I am of the mind that a blade of light is using Hydaelyn's power with us as a conduit. When we strike the aforementioned Ascians, it is the same as killing them and dispersing their souls into the well of life energies. Hydaelyn controls this well. Working as a way to continue the cycle in a way that keeps the reflections as stable as they can be. It is mentioned by Emet that while anyone can raised to be one of the 13, only the truest of servants make the best agents of Zodiarks will. This means Hydaelyn even redistributes the aether of her enemies. Nabriales, Igeyorhm, Emet Selch were all hit and killed by a blade as you mentioned. This does not necessarily mean the souls were destroyed, only cast into the lifestream to be fragmented further by Hydaelyn. Ready to be reborn as individuals who can once again be scouted by the Ascians to serve a vacant office.

Mind you I have no proof of this, only theories.

White auracite only traps a soul temporarily, it is used to keep an ascian in place as they have the ability to flee into the Aetherial Sea. The sea and the lifestream are two separate places as Minfilia mentions when explaining white auracite. Ascians use the sea to avoid being drawn into the lifestream. White auracite is used to buy time for a blade of light to be forged (and be powered by another source as Hydaelyn is too weak to be called upon), as evident by how Thancred used it to stall Emet during the final moments of the battle, allowing us to forge a blade and kill Emet.

Riastrad So one thing has been bothering me with what you said here and that was Minfillia saying that the life stream and the aetherial sea are two different areas and the ascians go to one to avoid the other, however I found that cutscene you are mentioning on YouTube and she says nothing like that at all. The quest is What Little Gods are Made of

What they are saying about the Ascians is that they use the crystal of darkness to be at the edge of the Aetherial Sea to stay on its shore and not be sucked in via the rebirth process. They also use the Sahagan priest as an example of him being obliterated due to not having one of those crystals.

I will also add in that as saber has said so far as we know the blade of light does not work in the sense of splitting more in the sense of obliterating.

Btw no one is saying that you need to stop talking about the theories that you have. Theories are good and fun. That's one thing this board is made for. For everyone of us of like mind (meaning we enjoy theory crafting weither we agree on said theories or not) to get together and bandy them about as well as discuss the wonderful lore of the game..
