The Lower City was a section of the metropolis that covered the city world Taris approximately 4,000 years before the Battle of Yavin. It was home to Taris' under-privileged classes. This was particularly true of nonhuman residents who, due to the dominant anti-alien sentiment, were confined to living there by law. The Lower City was located beneath the towering skyscrapers of the Middle City and the Upper City, but above the bowels of the Undercity. The upper-lower levels were dominated by slums with streets littered by filth and refuse.
