Deep Core

The Deep Core, sometimes referred to as the Core of the Galaxy, was a brightly lit region of the galaxy that lay at its very heart. Despite the presence of important city-worlds such as Troithe, Byss, and Empress Teta, much of the Deep Core was a thinly populated and densely packed mass of stars and planets, dangerous to navigate and largely left alone by galactic explorers. At its center existed the Galactic Centre, an ancient, supermassive black hole that bound the galaxy together. Traveling towards the Core and away from the galactic rim was referred to as going "coreward."
