Questioner
Hemalurgy is mentioned as something that has "broad implications." But that's of Ruin, right? (Or now it is of Harmony.)
Brandon Sanderson
Yes, but don't take the "of Ruin" and "of Preservation" too strongly, but yes.
Questioner
But, I mean, somebody couldn't just walk along with a metal spike on, say, Nalthis, and stab 'em and now they have the power, could they?
Brandon Sanderson
If they knew where to stab them, yes, they could.
Questioner
Anywhere in the cosmere?
Brandon Sanderson
Yes.
Questioner
You can stab someone and get their power?
Brandon Sanderson
Hemalurgy has been built in such a way that it rips off pieces of the soul. If you can rip off the right piece of the soul and attach it to somebody else, it will change your Identity, and it can rewrite anything that's attached to your soul. Identity, Connection, it can rewrite Investiture, all of this stuff it could potentially do.
Questioner
And do the things you stab people with—are they always metal or does that depend on the planet?
Brandon Sanderson
No, that's metal, that's—
Questioner
*inaudble*
Brandon Sanderson
Well yes, you could make it do something like that. That is totally possible. But the metal— Yeah. Anyway.
Questioner
With the other Shards you kind of have to be near that Shard to get that—there's no Allomancy.
Brandon Sanderson
To get it, yes. To have that part of your soul. But, for instance, Allomancy would work on other planets. The only one that's going to have trouble working on other planets, right now, are the ones on Sel because of the way that the magics are built.
