I not only think that this supplement is bold and inspired contribution to the Pathfinder cosmos, but, more importantly a prominent contribution to the corpus of fantasy (gaming and otherwise). This is not hyperbole on my part, but rather an honest assessment.
The supplement would have gotten a five star rating if it weren't for the uniforms worn by the military folk of Andoran. It's just too close to the Continental Army of the revolutionary war period. In a second edition, I wonder if this might be re-envisioned in such a way so that it is rooted solidly in Golarion and its lore. By my estimation, this would make a huge difference.
