San'Shyuum quarantine system

The San'Shyuum quarantine system is an unidentified star system inhabited by the San'Shyuum post Human/San'Shyuum-Forerunner war. After the Human/San'Shyuum-Forerunner war the San'Shyuum surrendered to the Forerunner subjecting themselves to a set of strict rules preventing them from technological luxuries such as space travel, and were placed under quarantine and constant surveillance.

The San'Shyuum's star system was shut off with a Forerunner shield, the same shield the Didact and Bornstellar would later have to bypass during their investigation of the Halo firing.
