859 Static Carillon

"Erde-Tyrene can burn, and while I will sigh at the loss, I will not care. What I do care about is that he broke our compact. He brought his abominations here. He violated the sanctity of my home."

- 859 Static Carillon to Blue Team

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 Gamma 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 him 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 from the human essences composed in New Phoenix. 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 him that he had not yet held up his part of the bargain. 859 then managed to bring Installation 03 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 he 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.

After preventing the Promethean forces from entering the portal, Static Carillon followed Blue Team to Installation 03 where he found that the Didact was already preparing to finish off the Spartans. The monitor disabled the Didact by shooting him in the back with his energy beam and used an emergency teleportation measure to transport the Promethean commander into the Halo's control room; according to the monitor, this was the only option to prevent the Didact from slaughtering the Spartans. After he and Blue Team recovered and discovered the Halo's Activation Index that the Didact had discarded when the monitor ambushed him, John-117 suggested that they fire the Halo to destroy the Didact. However, Static Carillon reminded him of the galactic-scale damage the pulse would cause, instead suggesting that the Master Chief use the Index to disable a set of safeties and thus allowing the monitor to scuttle the segment of the ring housing the control room and crash it into the Composer's Forge.

The monitor teleported John into the control room and detached the section of the Halo immediately after the Master Chief had deactivated the safeties. Static Carillon had to take some time to stabilize the ring in order to prevent it from breaking apart due to the missing segment; however, he managed to teleport John out of the control room in time before the impact destroyed the remaining Composers, causing them to discharge and digitize the Ur-Didact's consciousness. The monitor and John materialized aboard Blue Team's Longsword fighter in orbit over the Composer's Forge. Static Carillon thanked the Reclaimer for giving him a newfound purpose after millennia of overseeing a dead installation. He decided to take Gamma Halo for safekeeping and repairs in a location he did not disclose to the Spartans.

Trivia
Static is an adjective that refers to an object lacking in movement, action, or change. Carillon is a set of musical bells that are generally played by an automatic mechanism or by machinery. Thus, his name essentially means "unmoving bells", a reference to his duties to ensure that the Composers he maintained were never fired or rather "played".
