Structural Kylindrography

Upon approaching the black and green series of books, you find they mostly deal with documents about the structure, cities, and landscapes of the World. The word "Kylindography" that appears everywhere seems to hold the same meaning as one you had in mind: "geography".   As you get closer, you find a short explanatory pannel:  

Ah, the Cylinder: a structure so massive it would take two hundred days to walk from one side to the other, or to turn around. A true miracle. Even though our best physicists are currently far from understanding how it all holds together, nor how it was created by the gods, numerous expercts are working hard on the subject, in coordination with preciously knowledgeable thelologians from several religions.   In the meantime, a lot can be said about the massive diversity of locations that are present in the cylinder. This Encyclopedia, free from any explanatory or political bias, is there to present a diversity of structural locations from the Cylinder. The word Kylindrography, used thoroughly in the tome, has been created from the association of the Coastrel words Kylindro - the cylinder; and graphia - writing.
