The Islands are two subsectors in the Reft Sector.
The Old Islands subsector, first settled in AD 4512 (-9 Imperial) with generation ships and cold sleep capsules from Terra, developed and expanded with ships using sublight drives for nearly a thousand years.
The New Islands subsector was colonized in the second wave of settlement after the European Space Agency Long-range Colony Mission arrived in this sector of the Great Rift. It now boasts four major worlds with substantial populations. The most populous is Esperanza, far to the edge of the cluster, followed by New Colchis, Joyeuse, and Serendip Belt.
