I appreciated this supplement. Vibe and inspiration are clear and well-thought-out. Arts really brings you in and shows the clear direction where this module is going.
As for usability, I feel key components are missing, even when excluded by choice (e.g., DCs, recommended party level, etc.). I also feel the density of text, coupled with the smaller font size and color scheme, makes it harder on the eyes than it should be. I also have to add that if I were to print this supplement, I wouldn't know how to fold it to create a booklet following the format it was created for, particularly for pages 7 to 16.
Still, a good entry that shows skills, imagination, and creative direction.
