Was out looking for Planes of Power and stumbled across this and bought it. Not a bad little book although there are way better maps out there. Included maps of most of the new planes. One interesting thing is it included where all the portals to the Plane of Knowledge are; all the starting cities, Nexus, Fironia Vie, Overthere, and the Great Divide. Was kind of hoping they'd have Skyshrine, but oh well.
That sounds kewl.
