I don't see why we can't make with a map every now and then, seeing as it *is* rather difficult to follow several different characters with different perspectives. The details I can put into a post can only explain so much clearly, I admit.
Right now, Kevyn's image is quite accurate. I suppose I'd better cook up some other maps for areas further into the station as well, seeing as it looks like most of you will be going there.
I guess I also need to clarify that the vents are too small for some people, are also have their own sets of advantages and disadvantages for traveling through. The most obvious being that you really won't be able to see what's going on outside or communicate effectively with your team. Other pros and cons will just have to be discovered as they come up.
Ideally, I did this because I don't want everyone in the vents. A GM-based decision I had to make for this episode.
