As the two Realms, the Cognitive and the Spiritual, are, well, fictional... Are they all comprised of Investiture, completely?
Brandon Sanderson
Yes. No, completely? Well, here's the thing. Investiture, matter, and energy are all the same thing in the cosmere. So, just like energy and matter are the same thing here. So, yes, everything's made of Investiture, in the same way that everything's made of energy in our world. Does that make sense?
Aurimus
So, what about what spren are made of in the Cognitive Realm? Is that just Investiture?
Brandon Sanderson
So, yeah, I'll dig more into that. I'm gonna go with Investiture for now, but I could change that as I move along. What I'm kind of debating is, is there a separate Cognitive state, and I don't think so. So I'm gonna go with Investiture for now.

How about Connection?
Brandon Sanderson
Connection is, like, the equivalent of a quantum connection in our world, so it's more like a force than something comprised of something. The question is like, "What is gravity comprised of?" And then you start asking weird questions.
