Very interesting, GPNMilano.
This reminds me on a lecture I was going to give about The Great Shaft and the Aitrus Map, called "From Ae'gura to the surface". But I did not manage it before the Cavern was closed again, because it took me too long to collect authentic information about sizes, distances and dimensions.
Like mentioned here: (
Great Shaft), the Great Shaft is 3 miles in length. But I don't know the source for this MYSTlore information.
Do I assume right that 1 blender unit is about 1 foot?
If this is true, the shaft should be about 16000 blender units in height. But if those "3 miles" are meant to be Nautical League, your estimation of 50000 unit comes near the truth. I'm really happy that we will know this soon definately.
By the way, do you have any idea about the diameter? I made some "measures" some time ago, when the Cavern was still open, and counted exactly 200 male (walking, not running) steps for walking one 360° circle. Under the assumption that one step equals about 3 feet, this would give a diameter of about 57,3 meter or 188 feet (perimeter: 180m or 590ft).
I hope you can determine this finally.
