31 light years to the north east of the Manticore System and over five hundred light years from Earth, the system's location between the Star Kingdom of Manticore and the People's Republic of Haven made it a strategicallly relevant one between the two powers. (HH2, HH3)
Grayson Traffic Control directed all the incoming and outgoing traffic for the system.
In 1903 PD, the Star Kingdom of Manticore started to send money and supplies to help bolster the system's infrastructure and defenses. One of the agreements would be Manticore getting basing rights, establishing facilities (which would be shared with Grayson), and a permanent security detachment.
The First Battle of Yeltsin's Star occurred, and ended with the Navy of Masada patrolling the system. When HMS Fearless, HMS Apollo, and HMS Troubadour returned from the Casca System, they were ambushed by the Masadan LACs , which were all destroyed or captured.
Captain Honor Harrington and RMN forces set up a system of reconnaissance drones as a sensor net to help detect incursions from Masada. The Second Battle of Yeltsin's Star was fought between Masadan and Manticoran units, with an RMN victory. (HH2)
