So as to not derail the event thread further, there's a new WoB that I'll be quoting in the first post here to give proper attribution.
Feel free to discuss. I just didn't want to keep discussing Cosmere relevant info outside of the Cosmere forums.
Edit: the conversation has wandered to be more centered around magical foci, so if you just want to see the WoB itself, the thread probably isn't going to be very meaningful.
If you are like me and the topic of magic systems foci interests you, well, here's as good a place as any.
