Ok, it's been awhile since we talked about this, but I finally overcame my cranial-rectal inversion long enough to work out some dimensions and other specifics for the Wall. Seeing as how there is no possible way to map out the whole thing, it leaves plenty of room for others to do what they wilt with it in their own sections. One thing that occured to me as I was writing it up is that it kinda reminded me of Ringworld for some reason. But I'm wierd.

Comments and suggestions welcome.


Physical dimensions:

Length (est.) - 700 miles
Above-Ground Height (avg.) - 100 feet
Depth - variable
Width (avg.) - 100 feet


Exterior:

Smooth interlocking stone blocks 10'l x 10'w x 5'h, held together without mortar. The stone appears to be a fine-grained white granite speckled with black, giving the wall a brilliant appearance in direct sunlight and a ghostly glow in moonlight. In areas where the wall has fallen into disrepair, the blocks can be seen to be held together by staples of durable metal. The top of the wall has a plain 4' tall stone balustrade on either side, and in many places has been overgrown with trees and vines due to deposition of topsoil over the centuries. There are regularly spaced circular "ponds" (30' across, 5' deep) in the top of the wall approximately every 1/2 mile which seem to have been cisterns for the interior spaces, and are frequently used as rest stops for animals and travelers who are using the wall as a road.
 
There are trap door entrances into the wall from the top, approximately one every mile, but many cannot be opened or have been covered with dirt and plant growth. There are no staircases or other means of climbing to the top of the wall on either side, however in many places rubble, dirt, and other detritus has accumulated against the base of the wall, forming natural ramps which have, in places, been built up intentionally to reach the top. In some places along the wall, people have constructed other means of reaching the top such as scaffolding, ladders, or even staircases of stone, wood or metal. Many sections of the wall have fallen, allowing access to the interior.

Interior:

Almost anything that fits the stated dimensions - highly variable corridors, rooms, and cavernous spaces. The only regularly appearing features are the overhead cisterns, trap doors, massive centrally-located stone columns spaced every 1/10 mile, the 5' thick interior ceilings and floors, and the 10' thick outer walls. The columns reach from the roof to the bedrock (in some places far below the lower level of the wall) and are 20' across. Additionally, there are solid 10' thick walls stretching from ceiling to floor every mile, dividing the interior into compartments. In many places, these walls have been breached, intentionally or otherwise, and where the wall was built near or over natural caverns, erosion or the action of creatures or explorers has resulted in holes in the wall or bottom floor, allowing for a variety of creatures to roam the interior. The average interior space height is around 10', allowing for a total of around six floors (except for the large open sections, or areas with much larger (or smaller) interior spaces).
