ATROPINE was the first outer rim system to be colonized, which seems unlikely because it is so cold and marginally habitable.  But being out-of-the-way and inconspicuous is an advantage in certain occupations, and Atropinians have been moderately successful in taking advantage.  They are a high-technology society, and they are known to provide free use of their advanced tools to those who are willing to cut them in on their profits.  One particular region is known for its abandoned settlements, which are used for weapons tests and anything else too dangerous to do within populated areas.  The ruins could tell a story or two, if anything on Atropine was amenable to talking about what happens there.
