Overwatch network

The Overwatch network is a general term used to regard the collective core security and transit authorities of the Forerunner Ecumene. The overwatch network monitored, rationed and forbade travel to limit the buildup of reconciliation debt in the galaxy. Guardian Custodes were able to connect to the overwatch network, using it to reflexively counter many potential threats to the Ecumene long before they came to the attention of Warrior-Servant commanders.
