Wrender

To be fair, I said "that sword being carried around by that guy", not "Vasher and Nightblood". Do you remember Vasher carrying around Nightblood at the end of WoR?

Well this has been a fascinating read!!! I'm the one who wrote that review and Warbreaker recommendation. I've been a lurker here for years but I'm only just now making this account haha. It's really interesting to see how varied the guesses are. I'm afraid to say anything for fear of accidentally spoiling something. It's been SO HARD to not have anyone to talk to about this dang book! Although I will say (since WoB have already confirmed this) that there are some Szeth chapters starting in the later parts of this book, and they're really fun!
