The Hollerith System

The Hollerith System is a system so dense in population, that it was called a sector of its own. After quickly industrializing, the living species destroyed their ozone layer from their planet, killing all non-robotic life. Now, most planets are taken over by AI based lifeforms, droids. Most planets in the system do not have breathable air due to the lack of care from the droids to sustain the planets vegetation. A lot of planets are pure industrial factories of massive scale, and so are the largest production facility in the whole of eloria.
