859 Static Carillon

859 Static Carillon is a Forerunner monitor acting as keeper of the Composers and tasked with maintaining the Composer's Forge.

Biography
859 Static Carillon was created several centuries after the human-Forerunner wars, prior to the activation of the Halo Array. Static Carillon was charged as the keeper of the Composers and monitor of the Composer's Forge.

By July 25, 2557, Static Carillon had sent numerous messages to Installation 03's monitor 049 Abject Testament, who remained unresponsive. This caused 859 to travel to Installation 03 through a service portal to investigate. Upon arriving at the Composer's Abyss on Installation 03, the monitor was surprised to learn that the installation's Composer was missing. Upon noticing several Promethean constructs, Carillon came into contact with the Ur-Didact. The Didact recognized Static Carillon as the "keeper of the Composers" and had Static Carillon show him the entrance to the Composer's Forge. Upon their arrival 859 had the Didact agree not to manufacture more Promethean Knights if 859 brought a Halo to the Composer's Forge. When Blue Team entered the world from the service portal, the monitor solemnly revealed the Didact that the Spartans were entering. However, the Didact told it that he looked forward to welcoming the Spartans to his world.

However, the Didact soon broke the agreement between him and the monitor, creating more Knights. He intended to send them to Requiem to retake the shield world. The next day, Static Carillon was horrified to learn that the Didact had broken his part of the agreement. However, the Didact grabbed the monitor's shell and angrily reminded it that it had not yet held up its part of the bargain. 859 then managed to bring a Halo through slipspace to the sky of the world. When he informed Blue Team of the Didact's plan, John-117 decided they had to get to the Halo before the Didact. 859 decided to help them, not because it cared for humans but simply because the Didact broke his agreement. 859 helped Blue Team make their way to the portal and held off the Knights while they went through the portal, promising to look for a way to close it.
