The Hârn and Environs map was available for Free RPG Day 2012. It is a 33" x 22" poster map that shows the continent of Hârn on the front side. The back presents short descriptions of the cultures and regions of Hârn, about ten illustrations, a city map and two floor plans, as well as some advertisements for HârnMaster products.
This Free RPG Day promotional map is virtually identical to the map that is included in the HârnWorld Master Module.
The reverse of the map bears the Free RPG Day logo at the bottom right of the map along with the Columbia Games logo, a portion of the information on Hârnic barbarians is edited out to provide room for the logo at the bottom of the rightmost column.
