After reading the first post I must say that I find the RP interesting. But before I start thinking about a character and joining in, I would like to ask a question or two.

First. Are all law of physics (excluding the Cores and kages) the same as in our world? The first post does suggest so but I just want to be sure.
Second. Does a character need to have a Kage? (Probably was asked before but just to make sure)
Third. Are Cores and Kages the only fantasy stuff or there is more that I should know about?
Fourth. What is the status of women in Leginia? Are they more emancipated then in our world? Less? Roughly the same?
Fifth. Which level of computerized prosthetic organs and limbs does Leginia have? Can such prosthetic replacements be better then what are they replacing if they are expensive enough?
Sixth. Does computerized AIs exists and in which forms (in supercomputers, on the WWW or as robots) they come?
Last. What are the laws on civilians having demilitarized military vehicles (for example a tank which was stripped of it's weapons?) or producing vehicles which have everything a military vehicle has except weapons? AKA can civilians own tanks without guns?

Before this is answered I will be unable the crystallize a character for you to evaluate. So until then I shall wait.

BTW with your permission and regardless of me joining the RP I would like to try to draw and then use GIMP to digitize you a map of your world. If you wish that is.
