Do Fades have souls?
The question might sound weird but let me explain what I mean-
So Aginor made Trollocs by mixing human with beasts like Boar, Bear, Wolf (Strange in retrospect no?) Eagles and Ox- so on. And Fades have a 5% chance of being born from a litter of Trollocs. Being a "throw back" to the "human stock." Now correct me if I'm wrong but I thought I read somewhere that's a similar ratio to normal humans and those who can Channel right? Also Fades can't channel and it doesn't seem to be a biological block like Ogier. More like they simply aren't able to but instead are born in general and have weird abilities like being able to use shadow travel, sense channeling and "link" with Trollocs which seems very close to the One Power in usage. Traveling, Linking, Shadow Bending and so on. Trollocs can't Channel but they are mostly animal, Gholam were made specifically to be resistant to channeling so that makes sense why they wouldn't. But Fades despite being mostly human and having other abilities like channeling can't actually seize the one power.
I bring this up because Aginor himself thinks they simply don't exist in reality and or are out of phase with it. They don't have a sense of humor which even Trollocs do and was a big thing with Rand not losing himself or his humanity; Cadsuane wanted him to laugh and get his humor back. Though I think the biggest thing is they don't dream. Which we can assume at least as far as I know that everything else can dream including their parents Trollocs. Graymen can't dream but they're already dead and have given their souls to the Dark One hence what they are.
Therefor I purpose the theory which might already exist but I haven't see it- that Fades are Channeling Humans or those with potential to be channelers born from Trolloc stock and there for still bore with no soul but animated by the Dark Ones touch. Not his literal touch but whatever Aginor was able to use to create them that I would think the Dark One provided. Nothing we see in the story from the One Power implies the ability to create biological life- the Nym seem to be weird golems while Trollocs are actual Homonculi. The Dark One also can link with Corvids and Rats as well as with the True Power letting you control animals. (Though I guess you could have just used straight genetic tampering from the AOL but then why are they called constructs? Though so are the Nym too I guess...) Still my own theory stands I think!
