Well, most of the saucer section of this ship is supposed to be a part of the FTL drive system, or possibly a toroidal loop for a fusion reactor power plant, or maybe something else. The point is, there's energy being either produced or used out there for something, so the glowing ring makes sense to me from that standpoint. More than anything else, though, I just thought it looked cool as a lighting effects experiment. If Dennis
and his team want to do something along these lines, that's up them. I'm just playing around a little.
