I was a bit disappointed. We get deck plans. But it's an open system supplement, thus there's no crunch on the NPCs, meaning you have to build them all yourself. And the plots... well, they're a bit useless at times:
"Free from immediate danger, the characters find that something has been hidden on their persons or within their effects. This item might be a key, a map, a magical talisman, or something else. Regardless, someone comes looking for it, and they're not friendly.... The only thing to do, of course is to use their new possession to gain greater leverage against the various forces who are involved, and the only one who knows how to do that is Kimbal himself. Unfortunately, Kimbal fell from one scrape into another, and must be rescued from serpent people, sea devils or some other horrific and inhuman race. Breaking into their lair and breaking out again with Kimbal will take some careful planning and some capable fighting."
That's not the result of being an open system. That's a writer not making choices in crafting a plot.
