From the introduction: Phaemorea is a classic High Fantasy genre game world which could be plugged into any system. While written to work best with Classic D&D, it can easily be ported into any version of D&D, or with a little more tinkering, any system that supports high fantasy. I wanted a new entry level world for beginning players, as well as an alternative world for older players who want to experience D&D in a new way, without losing any of the charm of the old way.
