There isn't one. Its a quick and dirty set of rules for gnerating the basics of a sytem, mainly for placing the mainworld, belts and GG, with some basic (nonuwp) data about the other planets. It's based off of Jump shadows and orbits - loosly defined. It's explicitly not a detailed system generation which will be in another book.
I stand corrected. I said worlds when I meant System generation.
As for the Sample Character... starting age of 16, age at the end of second term is 28?! That thing is full of bugs. A sample character generation is supposed to make it easier this was one where I stopped caring in a couple paragraphs. The character took injuries left and right without undergoing any medical care. The list goes on.
