Located on the border of the Banu Protectorate, Corel System is one of the busiest tradeways in the Empire with long lines of ships waiting to clear both UEE customs and Banu trade guilds. The blending of these two civilizations is readily apparent on Lo (Corel III), where a large Banu population lives alongside Human settlers, creating a culture that is entirely unique to the area. Besides Lo, Castor (Corel IV), a frozen desert world, is the system's only other populated planet, albeit sparsely.
