These two are probably pretty significant ones.
This is a map showing all of the Outer Planes of the Great Ring...
The second is of all of the Inner Planes (including Para-Elemental and Quasi-Elemental)...
The lines are a little faint as I've had them scanned quite a while ago, I've since lost the original source of the image, but I can touch them up and colour them in PhotoShop...
I think that these will look quite good colored in.... they have alot of potential .
