This latest in LZW’s series of battlemaps with a connected storyline brings characters into an otherworldly realm “paved” with something that looks like green cobblestones. The artwork is beautifully executed, but perhaps a little too tightly tied into LZW’s ongoing story. The map is long and thin, with unfortunate bottlenecks at a few points, making it a little bit “railroady.” The really significant negative, though, is the depiction of Abaddon chained at the end of the “room.” Having him pictured on the map ties him down, either making him more of a terrain feature than a creature or forcing players and DMs to ignore the printed representation if Abaddon gets loose. Also, although the artwork here blends beautifully with the artwork in LZW’s Ground Set #15 - Astral Plane, the Astral Plane tiles are 6x6 and the Plane of Havoc tiles are 7x10 with well-defined outside borders, so they don’t really fit together that well as a practical matter.
