Was Nightblood used to collapse the perpendicularity from the aether world?

[Sythrin]

Cannot remember how the world is called in Emberdark. Buts it mentioned that the perpendiculartiy their disppaeared.
2 ways that can happen, is if the Shard disappears from the world and second that Nightblood can make it collapse. Not clear if stays drained, but probably it will take time before enough is gathered for a new perpendicularity.

Dhatri - It wasn't that it "disappeared" it simply says - IED Ch 22:

Spoiler

Unfortunately, Dhatri didn’t have a perpendicularity anymore. Which meant you couldn’t hop out of Shadesmar there to visit it. 

A Shard departing would only matter if the perpendicularity was there because of the Shard's presence in the first place. There are other ways a Perpendicularity can form; and many ways for them to be closed. TLM Spoilers:

Such as when Marisi collapses Trell's perpendicularity by getting the Mistings to all burn away the raw investiture.

Nightblood may be able to collapse most perpendicularities, but that is far from the only method. And we do not even know how a Perpendicularity may have formed there in the first place (or why).

I have a crack theory that the perpendicularity on Dhatri moved to Lumar. Very little actual substance, but there is a WoB that Xisis arriving had something to do with the departure of the Iriali. There's another thread somewhere wondering why and how the Iriali left all at once. 

The perpendicularity on Dhatri was probably formed from Aether investiture -- we don't have proof, but we know Khriss theorized that Shardless perps are possible, and Aethers have a ton of (purportedly) Shardless investiture, so it stands to reason. What if enough Aetheric investiture fled from Dhatri due to the Dark Aethers to make the perpendicularity move to the next largest bastion of Aethers, Lumar? While we don't know if the Iriali's arrival would coincide with the arrival of the perp, we can assume that an overnight disappearance would necessitate a perpendicularity. Also, Xisis could be studying Aethers on Lumar and ALSO secretly controlling a perp that has access to raw Aether -- and the arrival of a dragon who wants to control the only method of mass exodus might compel the Iriali to depart from Lumar.

Concentrating Investiture by using Aether spores to create a perpendicularity does seem a pretty good method as with the help of the Primordial Aethers they could ask and recieve a ton of it to make it. This would also mean though that when the Investiture is drained like in TLM, it would not regenerate as it was not due to natural accumulation of Investiture (otherwise nature would have cycled it again to collect it as a perpendicularity)

Unpublished Aether of Night:

Spoiler

In the trunked Aether of Night novel all aethers were paired: Verdant with Amberite, Ferrous with Beastarin, and Night with Luminous. Tress revealed that there are 12 aethers now instead of 6 and some of the names (amberite to roseite; beastarin to crimson; night to midnight) and powers differ but I think it could still point to some things. In the novel both Night and Luminous had teleportation powers (among others) but split in an almost metallic arts kind of way. In Tress Midnight no longer seems to grant that ability so I could see canon Luminous (if it still exists) have souped up version of the powers it had in AoN. This could become something similar to elsecalling and perpendicularities. I think Dhatri had a perpendicularity due to the presence of the Luminous aether but something happened to it during the war with the Dark Aether mentioned in TLM. I know I am making a lot of leaps here without much support but this was where my mind went.
