Unknown Regions

The Unknown Regions, also referred to as Unknown Space, the Unknown Territories, the Unknowns, and the Outer Reaches, or the Great Unknown was a region of the galaxy located in the galactic west beyond the Outer Rim. Largely unexplored throughout galactic history, it remained a mystery to space travelers and served as a source of tales and wonders.
To those who lived in the Unknown Regions, it was known as the Chaos. They knew the rest of the galaxy as "Lesser Space." The Chaos was a very dangerous place to navigate due to supernovae, black holes, gravity wells, and stranger phenomena. These hazards made navigation computers unreliable within the Chaos, and were the source of the name "Chaos." Due to such hazards, the peoples of the Unknown Regions employed Force-sensitive navigators, individuals endowed with the Force power of precognition, to navigate. When navigators were unavailable, long hyperspace journeys had to be jump-by-jump instead.
