So, this may sound a little bit ridiculous, and don't get me wrong it is, but hear me out. What if Lift could go to the Spirit Shores? I believe that Hoid and Lift have something in common, in which they both can somehow break into the spiritual realm places somehow, maybe through like an anchor. And don't ask me how my brain got here, trust me, you don't even want to know.
Also I didn't know whether to to put this in Cosmere or Stormlight, so I'm putting it in Cosmere because this is pulling information from both Emberdark and Stormlight, but I'll put a spoiler warning for any spoilers for Isles of the Emberdark, and forgive me if I put this in the wrong topic.
Lift
I was thinking about what Lifts role would be in the back half of Stormlight Archive, she's obviously very important seeing as she is going to be a flashback character. I was mainly contemplating what her boon and curse is. Now, Cultivation did a number of weird things to her, like her existing partly in the cognitive realm and being able to convert mass to investiture (lifelight), but one of the most interesting to me is why she can just go into the Stormfathers visions. I don't know how or why, but my guess is that she has some sort of weird connection to the spiritual realm, which allows her to go into places of the spiritual realm.
Hoid
Something I found interesting was that Hoid could go into Odium's visions somehow. In Rhythm of War, he goes into the vision that Odium sets up for Kaladin to try to break him.
Isles of the Emberdark Spoilers:
How do they do it?
I was thinking that maybe they would use some sort of anchor to bring them into the place they want to go in the spiritual realm just like when Dalinar and Navani go into different visions in Wind and Truth. Also Lift mentions she could enter the visions because Dalinar was there to guide her, so he could have been a possible anchor somehow?
Spoilers for Emberdark:
Could Lift go to the Heralds little Vacation Home?
I think using this same logic that Lift could theoretically break into the heralds visions. I mean, if she needs some sort of anchor that would be easy, because she could get something from her Nale hunting days. Now if that happened, it would make the already bad sitcom worse.
Now, none of this stuff is actually going to happen obviously, and again, don't ask how my mind got to this.
What do you think of this theory? Is it stupid, is it completely implausible and did I miss something that completely debunks it? Have people already thought of the same things as I did? Feel free to trash on this crappy theory all you want, because until then this is going to be stuck in my head.
