The Idaho System was an independent star system with a small population 72 light-years from the Star Kingdom of Manticore.
It was home to a terminus of the Idaho Hyper Bridge, discovered in 1905 PD, which connected it with the Zunker System near the Solarian League. When the League Office of Frontier Security tried to take control of the Zunker Terminus, the Idahoans used their influence with their Manticoran allies to make the OFS back off.
Prior to the discovery of the hyper bridge, Idaho was a relative backwater, completely overshadowed by the bustling trade and economy of its Manticoran neighbors. (HH13)
