This is an excellent, weird resource for generating cults, orders, monasteries, etc. that are deeply strange and uncanny, perfect for fantasy games. As written, the (minimal) setting provides Shadowrun style missions in an endless fantastic city, dense and layered and dripping with mystery and forgotten secrets, but it's easy to use either the organizations or the quest generators by themselves. It also has possibly the best use of public domain art I've ever seen.
It does require some adjudication on the DM's part; adding flavor and interpreting the results might take a little effort. Part of the flavor generated is from a series of strange images with a grid layered over them, giving you a section of a picture to improvise further details from, but honestly the entire thing works without this if you don't like it.
