I found this setting supplement to be delightful and well thought out. The presentation was on point. A former sahugin fortress rebuilt into a  cosmopolitan trading city, Fathoms Deep is an ideal base of operations for a seagoing campaign with amusing references to bothWaterworld and The Little Mermaid, while supporting a variety of play styles.

This was one of the first products I bought here and lead to my exploration of the OSR in general. While derivative of the random tables in the DMG, it expands them with flavor . This came to me at a time when I had no regular gaming group, and not only helped fill that gap, but lead to the successful creation of a long term online game revolving around a megadungeon. The tone is excellent, and I love the callbacks to the Fiend Highly recommended.

While purile and revolting, this is fully worth the purchase price for the resurrection mutation tables and the collection of weird magical items, mostly of limited use, and all dangerous to use. It is enough to break the cycle of humdrum plus whatever items, and make magic scary again.

This clever setting provides the most plausible circumstances for there to be a class of adventurers within a fantasy world. It is written without system, but functions as a background or aspect for any system. Well worth the recommended price.
