Questioner
So, Shai and forgers. She forges the emperor’s soul, then she got to track by practicing on [Gaotona], and it kind of held for a minute since he was close to the emperor, and that means it was right. So it was basically trial and error.
Brandon Sanderson
It was.
Questioner
So even if she have a lot more time and a lot less information, she could’ve guessed?
Brandon Sanderson
Potentially, there’s a certain distance trial and error will take you; in a reasonable amount of time, there’s a certain distance that can take you.
Questioner
And in an unreasonable amount of time?
Brandon Sanderson
Unreasonable, yes. You can just trial and error your way through a lot of things.
Questioner
And by seeing it held on him for 24 hours of time, that means she got really close.
Brandon Sanderson
Yes.
Questioner
And when she was forging herself, she was basically forging lies.
Brandon Sanderson
She was forging lies, but she knew how to make them really plausible for herself. Plausibility is a really big part of it. Can you convince the soul to not just of yourself...
Questioner
The decisions that she could have made?
Brandon Sanderson
Yeah. That they were realistic, that they were there, that she could have made these, that everything lines up in the past. It’s a little like programming.
Questioner
So that’s why she could add a little bit to the emperor’s soul because that’s also plausible?
Brandon Sanderson
Yes.
Questioner
Could she have changed him more if she knew more about him?
Brandon Sanderson
Yes. She created a fake soul and put it in him, there are possibilities beyond what she did.
Questioner
So she could’ve gotten a bit wrong if her trial and error made it plausible instead of what happened?
Brandon Sanderson
Now, at least in her perspective, what she did was create a fake soul and put it in him. What I haven’t answered is did she just take the soul that was lingering on the body and fill in the gaps? Or did she legitimately craft a new soul? That I’ll leave to the cosmere philosophers to talk about.
