Loves Your Favorite Game
To me, that's a flowery description of the DM's whole job, so yes, I would read that as offering support for all the various needs of the DM, including base understanding of the role. Especially, again, if viewed from the perspective of a tyro. Nothing about it, to me, indicates experience required.To me that quote tells me the guide is primarily about weaving/creating legendary stories instead of a manual on 'how to run the game'. I really don't understand how you take that line to indicate instruction over content creation.
