The latest installment of Jonathan Robert's Fantastic Maps-line is 51 pages long, 1 page front cover and 1 page how to use, leaving 49 pages for the maps.
As is wont with the Fantastic Maps series, we get a grided one-page overview-map of the Arboteum and its adjacent buildings and something seems to be wrong there indeed - after all, there's a gaping hole in the ground and several trees have been uprooted. The map also comes in both full color and b/w blown-up versions for use with miniatures, an alternate A4-version for Europeans like yours truly, high resolution jpegs with and without grids and a maptool version of the map.
Jonathan Roberts delivers a beautiful map that some of you might already know from the stellar "Breaking of Forstor Nagar" adventure. As its direct predecessor, that means that some of the rooftops that have been largely cut off are slightly blue-tinged. However, due to the rock-buildings and colorful nature in the arboteum, this blue-tinge is not nearly as dominant as in the predecessor, making this map probably much more useful to DM who want to use it for other adventures/locations than BoFN. Thus, my final verdict will be 4 stars, as the blue-tinge still is there and could limit usability for rather nitpicky persons.
[4 of 5 Stars!]
