A product centered around the titular fey-related location, with associated quests, NPCs, and magic items. They also include two PC races, dryads and selkies, which only seem loosely related to the other material; that's not really a problem, though. Overall, the product is fine and a fair deal for the price, although the formatting is a little odd at times. The main issue is its tendency to lean more towards inspiration than concrete information; in particular, what made me knock this down from four stars to three were the NPCs, which you're largely left to build on your own based on their descriptions. I don't buy game products like this to do the work myself...
