I’m not sure it says anywhere in the booklet, but who actually worked on this great product? Jeremy Crawford said on his QA the other day he worked in the rules and Richard Baker/Sasquatch games made the adventure.

I did, indeed, make the Starter Set rulebook. Rich Baker and Chris Perkins wrote the marvelous adventure.
