The Inner Core Worlds were a series of star systems that were discovered in 4,000 ABY. They were within 500 light-years of the Galactic Center. A handful of the planets were discovered to be habitable. This sector of the galaxy took the full brunt of the Destroyer Wars from 4,020 ABY to 7,834 ABY, and the Inner Core Wars from 8,000 ABY to 9,000 ABY.
