This goes back to that whole geography discussion and how much math is known and by whom. (Did I get that right Mark? :-) My working hypothesis is that both visualization and coordinates can be used, and more skill is required for coordinates (and a greater knowledge of math?). Something I have been wondering is: What is used as a reference for coordinates? Probably the Orb and two other objects (x,y,z) (think GPS), but they need to be small (so not the Greater or Lesser Sea) to reduce errors. Perhaps there's an e'Barrit system and a Lavode system and a e'Drien system, etc. The e'Barrit system is probably x,y,z with the orb and special staffs or objects. The Lavode system would probably be something more complicated like polar coordinates (distance, angle from north, angle from ground level (altitude). Then you only need the Orb. I would bet necromantic math is something else entirely. Sorry for rambling, geometry and mapping is a hobby of mine. Ken __________________________________ Do you Yahoo!? Yahoo!
