The Babylon system was the Star system which orbited the planet Babylon. The system served as operational site for the Aradani Royal Navy and was forbidden for civilian travel. By 19 BBY, CSDF operated here and had erased the Obitus subsector from Imperial star-charts to halt Imperial advance. An abandoned CSDF flotilla was left to safeguard the planet onwards.
In 2 BBY, Empire of the Hand scouts discovered the system but helped continue its isolation.
