This three page PDF delivers on its promise of 100 Fantasy City Rumors and Mysteries. While some of them are a little underwhelming ("GOBLINS ARE TUNNELIN' UNDER OUR WALLS") there are many, many more that are imaginative and interesting, and well worth the price of attendance. Because they are numbered, you can easily roll a couple d10s or a bonafide d100 and then just run with the randomly-generated idea. While the book claims they are city rumors, these could easily be implemented in any string of civilization. What's preventing a mad inventor from setting up shop in a sleepy little village, or a merchant's daughter from being kidnapped by purple-masked men in a tiny town? That might make things even more interesting.
Get it if you'd like a generator for random, cool and evocative adventure ideas, or if you're in need of some inspiration. It works with practically any fantasy game you can think of.
