Mausoleum of the Arbiter (Earth-5875)

"Here rests the vanguard of the Great Journey. Every Arbiter, from first to last. Each one created and consumed in times of extraordinary crisis."

- - Prophet of Truth

The Mausoleum of the Arbiter was a massive chamber located in the higher districts High Charity, housing the remains of the Arbiters of the Covenant.

History
After Fleetmaster Thel 'Vadamee was branded with the Mark of Shame, he was dragged by Tartarus and two jiralhanae to the Mausoleum of the Arbiter, where the Prophet of Truth and the Prophet of Mercy awaited for him. They then ordered Tartarus to release 'Vadamee, and after ordering the jiralhanae to leave, the Hierarchs conversed with Thel about past Arbiters and Sesa 'Refumee, a heretical leader of the faction known as the Light of Truth. They then made 'Vadamee their new Arbiter, and sent him to quell the heresy on the Threshold Mine in the Soell system.

With the Great Schism, many sangheili held their final defensive within the Mausoleum against jiralhanae soldiers with support from many mgalekgolo, leading to a massive and bloody battle. The remnants of the battle were massacred by SPARTAN-II John-117 when he stormed through High Charity to search for Commander Miranda Keyes and Sergeant Major Avery Johnson, as well as to stop Tartarus from retrieving the Activation Index from Installation 05. Just as John reached the Hierarchs, they were attacked by xenomorph Facehuggers, and the SPARTAN was forced to pass through the Mausoleum once more to reach the Dreadnought at the center of the city.
