When will you clear up the things at the end of Bands of Mourning?
Brandon Sanderson
That is mostly setup for Era 3 of Mistborn. You can find some answers in Arcanum Unbounded; if you haven't read that, I would recommend that. If you get the the end of Bands of Mourning and you're like "huuuuh?" there are some answers in Arcanum Unbounded, but mostly I'm doing stuff that is Era 3 of Mistborn, which will be written after Stormlight 5. There will be a Wax & Wayne 4. Wax & Wayne 4 will touch on these, but it's not the central theme of the Wax & Wayne books; it's the central theme of Era 3.
