From publisher blurb: Sometimes the call of adventure comes, not from the stars, but from under the waves! Diesel Punks deals with a science fiction setting and that usually means space travel. What about 'aliens' coming from the Earth itself? Atlantis gives notes and rules for playing six water breathing races, each with their own biomes and biology. This book lets you not only meet the aliens but become them! You can play the warlike Blue Atlanteans, the enigmatic Red Mages or the playful shape shifting Green merfolk- or opt for the stranger dwellers of the deep, the feral Abyssals and the shy Lava Miners. Sea folk are a part of many mythologies and media, now you can be one. This product requires The Black Hack Second Edition to use.
