Installation 05 Control Room (Earth-5875)

"What is that place? Where the High Councilors were meant to watch the consecration of the Icon: the start of the Great Journey."

- - Thel 'Vadamee and Rtas 'Vadumee

The Installation 05 Control Room, also known as the Chamber of Consecration to the Covenant, was the control room of Halo Installation 05, being located on an island in the middle of a massive sea section.

History
Following the arrival of High Charity at Installation 05 and the Changing of the Guard, the sangheili High Councilors were sent to the Installation 05 Control Room under the pretense of preparing for the activation of the Halo and witnessing the Great Journey. They were betrayed by Captain Melchus, who, alongside a pack of well-armed jiralhanae, massacred the Councilors, taking the few survivors to the Bastion.

Tartarus was sent to the Installation 05 Control Room by the Prophet of Truth with 343 Guilty Spark and Commander Miranda Keyes, hoping the latter would activate the ring and start the Great Journey. Before being able to force Keyes to do so, Tartarus was stopped by Arbiter Thel 'Vadamee and Sergeant Major Avery Johnson.

Despite 'Vadamee's best attempts to convince Tartarus to admit the Great Journey was a lie, he forced the Activation Index into the control room's panel, activating the firing systems of the Halo. The Arbiter, Johnson, and many sangheili High Councilors, Zealots and Special Operators teamed up to kill Tartarus and stop him from activating Installation 05. Using the Fist of Rukt, Tartarus was able to slaughter many of the sangheili despite being severely outnumbered and outgunned. When the Arbiter was able to kill Tartarus with his Type-1 energy sword with Johnson's help, the Fist of Rukt fell to the ground alongside its leader.
