The Boradis system was an inhabited system.
The system was affiliated with the United Federation of Planets in the 24th century, with the first outpost established in 2331 on Boradis III and three others by 2365. Nine other Federation outposts were established in the sector. These thirteen colonies had minimal defenses.
In 2365, the USS Enterprise-D, just outside this system, intercepted a Klingon sleeper ship IKS T'Ong from the late 23rd century and prevent it from attacking the Federation colonies. (TNG: "The Emissary")
