Yea, between Dave, and Buttercup, I was totally sold on this product.
It is essentially this:
There are 9 maps, each two-sided. Each map is the size of 4 8.5x11 sheets of paper. The maps form an area comprised of 3 maps wide, and 6 maps tall. Each map is made up of hexes. Each hex is 5 miles wide. The entire map covers an area of about "750 miles wide by 1020 miles long". For reference, it is 600 miles from Indianapolis to D.C. or from London to Berlin.
Many of the hexes have detailed information about what is found in each hex. For example:
"0910 The Stone Tablet: A large pitted stone tablet is partially covered with grass. The right side of the tablet is hollow and contains several flutes. Carved on three flutes are maps to the ruins in hexes 1016, 1514 and 2301."
That's a small one. There are essentially 400 pages of these little descriptions like this, each encompassing the area described.
There area also broad descriptions of specific regions or geographic features which are spread over multiple hexes.
The flavor is very rich, and very evocative. The "world" as it where is a hodge-podge of cultures and civilizations from high tech "tinkering" gnomes to savage cavemen. It also runs the range of ELs from wild boars rutting for truffles to encounters of "dragon swarms". I saw at least one EL 20 area, but it wouldn't surprise me if there are area of 20+.
That's it, in a nutshell.
