Like most other map folios, the Iron Gods Poster Map Folio comes with three full-colour poster maps suitable for use with the Iron Gods Adventure Path, but also usable with other campaigns set in Numeria.
There is a map of Numeria itself. As is standard for country maps in these folios, it is done in the style of a map the PCs might actually use in-world and can be freely shown to players. It is beautifully illustrated with pictures of monsters and very setting-appropriate robots. I am also happy to say that, unlike the map of Osirion in the Mummy’s Mask Poster Map Folio, this one has labels of cities, towns, and other major landmarks like Silver Mount. This makes it much more useful in actual play and not just something pretty to look at.
The other two maps detail Starfall, the capital city of Numeria, and Torch, the town Iron Gods begins in. The map of Starfall is rather uniform in colour, (mostly shades of brown) making it less interesting to look at, but it remains useful for gameplay. There is a lot of brown on the map of Torch as well, but the town’s smaller size means more variation and detail can be included, making it not quite so uniform as Starfall.
Overall, the maps are definitely worth it for any campaign set in, or passing through Numeria.
