For anyone interested in some expansion content for MotW, look no further than the recently kickstarted Codex Vol. 1! It funded in less than 2 hours and has a mystery in it called “Huge Problems in Little Shanghai” as well as content for many other PbtA games. If you are looking for a diverse, inspirational and varied resource for your gaming table, there is nothing better.
