Overwatch network

From Halopedia, the Halo wiki

Portal facilities, such as the Menachite portal complex, were administered by the Overwatch network.[1]

The Overwatch network, also referred to as the "core authority"[2][Note 1] 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[3] - though was never able to fully mitigate these effects throughout the long history of the empire.[1] To aid in this endeavour, the Forerunners constructed Slipspace portals, with the network requiring elaborate security keys and passcodes before travel could be permitted.[1]

Peacemaker constructs such as 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.[4] [5] The Didact noted that they could track slipspace journeys if they were rational, while irrational series of jumps were harder to track. He used this to an advantage while on the run from the Forerunner authorities shortly after he was revived from his exile in a Cryptum.[2]

List of appearances[edit]


  1. ^ While never officially referred to as such, the core authority mentioned in Halo: Cryptum and the duties of the overwatch network as described in Halo: Warfleet are almost exactly the same. Furthermore, the term core authority is never presented as an official name, but instead a general descriptor, leaving it exceedingly likely the two organizations are one and the same.
