Kurkistan
So you've said that healing is like the Spiritual wants to heal and then it filters through the Cognitive, but how's that work with healing wounds to the soul like Hemalurgy or Shardblades? What do you refer to to heal the soul at that point?
Brandon Sanderson
You need to make a patch on the soul with Investiture.
Kurkistan
So how's the Investiture know where to go, what to look like?
Brandon Sanderson
Well your soul is an ideal. So if you can get it up there, there are ways to do-- to recreate that with um... See I'm getting into stuff for later books.
Argent
No, that's okay.
Kurkistan
So when Hemalurgy rips something off the soul, is that the ideal soul or some sub-soul?
Brandon Sanderson
That is off of your soul, and it can be healed; but what it's going to be doing is creating a patch of new soul. So it will not be your original soul. Does that make sense?
Kurkistan
Okay, that- well, not completely, but I think that's your intention.
Brandon Sanderson
Yes.
Bystander
If you do that, is that like Frankenstein's monster, or is it like a graft that's absorb--
Brandon Sanderson
Less horrifying- Less horrifying than Frankenstein's monster, but it is a graft that is like-- It is not your original soul.
Bystander
Yeah, but in modern medicine stuff like that is absorbed-
Brandon Sanderson
Yeah, in this you will always have a scar on your soul that something else has patched over.
Kurkistan
So Kaladin shouldn't just keep getting his arm chopped?
Brandon Sanderson
*ignoring/not-hearing Kurkistan just now* But that is what happens with most forms of Investiture in the first place.
