It looks like we are done with the Set's and Telsin's stories, so can you share a bit about how the organization started and/or how Telsin joined them?
Brandon Sanderson
The Set began, honestly, as a domino effect of things Kelsier was doing on-world. It is his fault. He wouldn't necessarily take responsibility for it. A group of people who knew that things were happening behind the scenes and through various machinations and things like this decided that there was power to be had, from what they didn't quite know was off-world yet, but that they knew there were basically ancient gods. This was a great opportunity for certain individuals and beings around the Cosmere, specific ones, to take over the reins on this. People who begin looking for ancient gods find them, it turns out, in the Cosmere, sometimes.
Telsin was involved from a young age and Wax's parents were not. Wax's uncle was. I don't think he actually recruited her, as I remember. It's been a while since I went through these things. He, being part of it, was part of how she found her way there, if that makes any sense. Telsin's always very ambitious, and always knew... Telsin can be seen as a bit of a model for the Set itself, in that she knew there was more out there that people weren't telling her, and she found it and then it consumed her.

People in the chat are saying that Telsin recruited Suit.
Brandon Sanderson
That's right, Telsin did recruit Suit. Yep, Telsin recruited Suit. She was looking for things, she found her way to it, yeah. So there we are. Edwarn, Suit is his title. Yeah, I knew there was something there, but it's been...
Like I said, view Telsin as kind of an example of how the Set itself came to be. And I have to talk around some things because I want to write Secret History sequels but I don't know if I'll be able to. And in them you should be able to see the origins of the Set. It is planned right now to be not... it's not like Kelsier founded it, but the ripple effects of things Kelsier was doing.
