The “Unite Them” shirt was a special shirt for volunteers and attendees at the Utah release party for book 3 in the Stormlight Archives, “Oathbringer.”
I was there as a volunteer in a Veil cos-play and as a beta reader for the book. If you have pictures from the event, I’d love to see them!
The glyphs are one version of how you can right "Happy Birthday" in Alethi glyhs. Left is "happy", right is "birthday" done to look similar to a two-tired cake.
