The recent Captain's Log 27, released in late December of 2003, has a map of the entire Milky Way galaxy. The F&E map is shown as taking up about 1/16 of the galaxy, though this makes up about 1/8 of the habital outer ring. (As you get closer to the core, suposedly the high radiation makes life impossible. Even for Tholians.)
The Omega Sector map lies a bit spinward of the F&E map, and is shown about the same size.
More interesting is the huge slaveing race shown occupying virtually the entire far half of the galaxy. A brief description:
"The Xorkaelians are the ultimate in Evil Enemy Empires. They enslave six entire sectors, and the sentient races there could only wish for the kinder, gentler life of Klingon Subject Races. The Xorkaelians are ruthless and just plain mean; they consider war and combat to be the first and only choice upon meeting another race. They never negotiate, never deal, never make treaties. Xorkaelian raiders were fairly rare until [2360] when they began appearing in large numbers. They may have developed their new technologies to fight Andromedans and then launched a xenophobic war of aggression after the Alpha Octant ended the Andromedan invasion."
I've never heard of these guys before this issue. They must be the next "Big Thing" for SFB.
