Sector containing J-25 system
This sector, containing the J-25 system, was, by 2365, unexplored by the Federation. It had been visited in the past by the El-Aurians and by the Borg, who had assimilated the civilization on the sixth planet of J-25. In that year, the USS Enterprise battled a Borg cube in this region. The nearest starbase to this sector was Starbase 185, which was at the maximum warp of the Enterprise-D two years, seven months, three days, eighteen hours away. (TNG: "Q Who")
