I have been going thru all the books for SM and Silent Death, and have found a ton of information, and a strong feeling that there was some sort of "guide book" for things (IE where things are located, historical reference points, etc). Multiple books refer to the same thing, but none of them have hard details. (for example, I Knew House Aramae was a thing, now I noticed in the old SD Overkill module that the second imperial lineage came from there). There is a consistancy that appeals to me.
However, finding out where a lot of these things go together (For example what was the fascination with giving SD locations with Z coordinates without X and Y coordinates? This kills me because I only have a third of the puzzle!)
So my question is this: Does ANYBODY have that old guide book? I am trying to build a cohesive model of the SM universe and I feel like an anthropologist, trying to figure out the cultures by just a few artifact pieces.
