It's 100% Hoid. There's a few lines in Chapter 5 where
SP3 Chapter 5 and Epilogue
the narator is talking about how they did the lightweaving to make Design look human, and how they're frozen in time and used as the coat rack. Hoid unfreezes at the end in the second epilogue before he and Design leave the planet.
I haven't downloaded the files yet. Wondering if it'll be a lighter tone like Tress, or heavier. I really liked Hoid telling Tress's story, and look forward to learning more about her world & its shard(s).
Avoid other messages in the thread because of spoilers. I’ll avoid them - it’s fantastic. One or two chapters left and I love the story so much. Probably one of my top 3 cosmere books. Was not expecting it.
*****spoiler on tone ******
Definitely not as light as Tress. Much heavier moments/concepts but with a lot of humor throughout the early parts.
