The Freedom City Atlas is a series of products intended to flesh out and further detail the award-winning Freedom City setting for Mutants & Masterminds. In this series, we "zoom in" to look at different facets of Freedom City in detail, providing you with all the information you need to know about them to make them centerpieces in one or more adventures set in the city of heroes.
Pyramid Plaza features the tallest buildings in Freedom City, the triple towers of the Wading Way business district, with a twist—literally! The towers each twist 360 degrees from their base to their rooftops, spiraling up into the Freedom skyline. Learn about the buildings' history, use, and secrets, along with information on the surrounding area, adventure hooks, and four full pages of maps and diagrams of Pyramid Plaza by Freedom City cartographer Phillip Lienau!
