This was a very well done. It covers Elysium, Carcerri, Bytopia, Beastlands, Grey Waste, and Gehenna, and is all excellently written. If you're going to adventure in any of these planes, this supplement will be invaluable. Only criticism is that with this download the maps are all chopped up into about 9 separate pieces each, so in order to be able to really use them you'll have to either copy and paste to some sort of drawing program or print it all out and then stick them together like a puzzle. Not hard, but kind of annoying (and the 2nd option would consume a heck of a lot of ink).
