There really is not a whole lot to this, other than a map and a few notes, largely because it was supposed to have followed, to a great extent, the narrative style of the original Inquisitor rules: Each player GMs, and builds off everyone else' work. Several versions of Twlight Sector were run, one of which resulted in the extermination of humanity and the triumph of Chaos (yeah, we screwed up pretty bad there).
Anyway, if there is anything here that anyone can use, please enjoy.
