Contents.
"Crucis Margin" details the Gateway Quadrant of near-Imperial space.
Publication history.
Judges Guild published "Traveller" supplements from 1979 to 1982, detailing full sectors of the Imperium, and according to Shannon Appelcline: "The result was a set of four publications: "Ley Sector" (1980), "Glimmerdrift Reaches" (1981), "Crucis Margin" (1981), and "Maranatha-Alkahest Sector" (1981). Together these sectors comprised the Gateway Quadrant; along with complementary adventures published by Judges Guild, they offered the most comprehensive and cohesive view of any part of the "Traveller" universe, with the possible exception of the Spinward Marches."
Reception.
William A. Barton reviewed "Crucis Margin" in "The Space Gamer" No. 46. Barton commented that ""Crucis Margin" will undoubtedly open up new areas of adventure on the trailing edge of the Imperium for those adventurers looking to escape the ravages of the Fifth Frontier War to spinward. Unless the dollar price hike over the earlier sectors is too much for you, this supplement should join them in your "Traveller" library."
Tony Watson reviewed "Glimmerdrift Reaches" and "Crucis Margin" for Chaosium's "Different Worlds" magazine, and noted that "As pre-generated sectors for "Traveller" play go, these offerings by Judges Guild are about as good as any on the market."
