The region from which RA started their reconquest of the South. A small and relatively poor region, one of only two in which no outposts have been built. Before the removal of static complexes, Cache had some of the best in the entire South, which is why RA fortified this region over Insmother. One of Cache's station systems, P7-45V, was the site of what was, at the time, the largest capital ship battle ever, in terms of fleet size and capitals destroyed (11 E.R.A capitals, 3 RA). When the Drone Regions opened up, Cache had a large number of connections to it.
