The third in a series of convenient and useful short publications aimed to provide content for high seas adventure. The ships used illustrate examples of the different vessels plying the seas in the world of Mhâr Fantasy RPG. Each booklet in this series contains statistics, background, combat maps, and an outline by which the ship may be used in encountered or used in an adventure. Of course, this does not include simply using a similar ship that the PCs may acquire and captain for their own adventures. The guide will help GMs using their other fantasy RPG systems to convert the ship and crew statistics for their own use. Although designed for the Mhâr Fantasy RPG, Merchants and Mariners units can be used with any gaming system using a similar setting.
