Every part of this module is pure radness. It's a good length--detailed, but not too detailed. In a similar vein, the art is incredible, but there's not an abundance of it.
My personal highlights are the Men at Arms and Hirelings table, which, though small, are packed with some disproportionately interesting details. The bestiary adds quite a bit of the right flavor. The dunes themselves, a literal sandbox, are great although neither the Golden Barge nor the Glittering Tower dungeons inspire me as much as the rest of the book.
The War Bears are actually the coolest part though. I mean, the name alone lets you know that.
