The Mystery of the Anonymous Supplement Writer
I regularly bemoan the fact that GDW allowed the Third Imperium to become not merely an example setting for their SF RPG Traveller but the setting for it. I continue to feel that, by doing this, it so firmly yoked Traveller's ruleset to a single setting that it subtly discouraged players of the game from making up their own settings and instead to rely on GDW and its licensees for more setting information to use in their campaigns. One such licensee was Judges Guild, which produced several Traveller adventures and sector supplements, one of which was Ley Sector, published in 1980 by an unknown author (there is no writer credited anywhere in the text). —Grognardia
What if it's a "Purloined Letter" scenario—and the author's name is "Ley Sector"?
