For other uses of "High Charity", see High Charity (disambiguation).

High Charity was the Covenant's center of government and mobile capital city, known as the Holy City of the Covenant or the Prophets' Holy City.

Physical description
High Charity was a massive mushroom-shaped structure, about 348 kilometers in diameter. It was partially constructed from an enormous chunk of rock that had been blasted away from Janjur Qom by the Forerunner Dreadnought, with the rest of the superstructure being built around it. Inside the hollow dome of the station was a massive multi-leveled city, and beneath which, within the foundation rock that the station was built upon, was a honeycomb structure of hangar bays and weapons platforms. An "artificial star" at the peak of the dome simulated natural sunlight within the city, and its glow would periodically dim and intensify to simulate day and night cycles. A typical day on High Charity was roughly comparable to 265 Earth hours. The interior artificial environment on the station was practically Earth-like with a generated gravity of 0.95G, a nitrogen-oxygen-argon atmosphere of 1.03 atmospheres and a temperature range of 50°F - 75°F (10°C - 24°C). The "stalk" beneath the dome was a mass of towers and antenna-like structures; some 8'930 semi-rigid umbilical docking tethers. High Charity was mobile, and could make jumps through Slipspace.

The station received the majority of its power from the Forerunner Dreadnought, the ship at the center of the city. The city was completely powered by the engines of the decommissioned Forerunner vessel. The Dreadnought's engines were powerful enough to run the city on a fraction of their potential output. However, the station also possessed a set of backup auxiliary reactors that were capable of generating enough power for slipspace travel.

Capital city
In the internal hub of High Charity lay an extremely large capital city with a population of just over 23,800,000, which was comprised of all the various races that made up the Covenant Hegemony. At the center sat the Forerunner Dreadnought, embedded within the city after the formation of the Covenant as a symbol of conviction and peace between the Sangheili and the San 'Shyuum.

The city itself contained many locations sacred to the Covenant such as the High Council Chamber, the Sanctum of the Hierarchs and the Mausoleum of the Arbiter. As a construct, High Charity was very similar to the Unyielding Hierophant, a repair & refit station, though it also served as a mobile command post. Unlike many small Covenant vessels and their UNSC counterparts, High Charity contained many courtyards and other non-essential spaces which gave the station a terrestrial feel. The interior of High Charity was filled with the Covenant's unique architecture, of a lighter tone than their naval vessels. All of the structures within the city floated above a methane-rich field in which the millions of High Charity's Unggoy dwelled. The massive towers around the dome were gigantic spires of volcanic rock from the city's base, interwoven with metal supports and covered with decorative alloy. They were used by the San 'Shyuum as offices and private residences.

Protection
High Charity was surrounded at all times by its own personal defense fleet, which consisted of hundreds of battleships, carriers and cruisers. Some of the biggest fleets in the entire Covenant armada defended the city, such as the Second Fleet of Homogeneous Clarity and the late Fleet of Particular Justice. It was also capable of refitting and housing thousands of vessels ranging in size from personal fliers to cruisers on its umbilical docks and within its internal hanger bays. As it was the Covenant's major religious center and capital, High Charity was enormously sacred to the Covenant. It was thought that true believers should visit it at least once in one's lifetime, though few of the Covenant could afford to do so. It was full of San 'Shyuum and Sangheili Councilors, and the general leadership of the entire alien hegemony. Hidden within the station's founding bedrock were carefully shielded weapons platforms which boasted firepower unrivaled by even the largest Covenant battleships. It can be assumed that High Charity also had its own set of powerful energy shields in addition to this.

In addition to its enormous defense fleet and impressive firepower, it was also guarded by a rapid detection network of slipspace probes. Anything larger than a millimeter in diameter that drifted too close was engaged and obliterated, including ships that failed to transmit the proper clearance codes within a millisecond of being hailed. The clearance codes that granted access to High Charity's space were also updated on an hourly basis.

However despite its considerable defense assets it was unable to prevent the Flood from infiltrating its interior. The station's shields are most likely why the Flood entered it with the In Amber Clad by a precise Slipspace jump: it allowed them to bypass any and all outer defenses.

Layout
Along the outer wall on the inside of High Charity were several towers, each containing rooms and hallways. Two of these towers were referred to by Cortana as the Mid Tower and the Far Tower. Most of these towers were connected to the two surrounding towers by the Hanging Gardens and the Valleys of Tears, but the towers containing the Council Chamber and the Mausoleum of the Arbiter were both notably only connected to the sections between them. Hanging far above the Mausoleum of the Arbiter was a part of the Sanctum of the Hierarchs, a large chamber decorated with shards of glass from worlds glassed by the Covenant. The districts located within the towers were collectively known as the Tower Districts, while the regions below them were referred to as the lower districts. The lower districts were home to most of High Charity's vast Unggoy population, as well as factories where Covenant war matériel was produced, such as the Assembly Forges and the Sacred Promissory.

Early history
Long before the formation of the Covenant, the San'Shyuum civil war between the Reformists and the Stoics ended when the Forerunner Dreadnought launched from the San'Shyuum homeworld Janjur Qom. The ship's launch ripped a huge chunk of rock from the planet in the process, which was carried with the Dreadnought during its escape. This chunk would later form the foundation of High Charity.

The station was erected during the Sangheili-San 'Shyuum war and completed following the war's conclusion. When the two races allied with one another, High Charity was made the capitol of the newborn Covenant Empire. It also became the surrogate homeworld of the San-Shyuum in 646 BCE, when Janjur Qom was destroyed by the stellar collapse of its star. The Forerunner Dreadnought was stripped of all known weapons and permanently installed inside the center of High Charity, its engines providing power to the entire station.

Prior to the Human-Covenant War, High Charity was almost destroyed when the Forerunner Dreadnought was powered up by Mendicant Bias, who was galvanized by the discovery of "Reclaimers" by the Covenant. Bias attempted to reach Harvest to transport the occupants to the Ark. It was accidentally deactivated by the Lekgolo who were used by the Covenant to probe the Dreadnought's machinery; a worm short-circuited the ship during the launch sequence.

The Sacred Rings and the Great Journey
Upon the discovery of Installation 04 by the Covenant, High Charity was supposed to perform a slipspace jump to the ring along with its fleet, where the Hierarchs would activate the ring to send the Covenant on the Great Journey.

The Fleet of Particular Justice, led by then Supreme Commander Thel 'Vadamee, had already made its way to the ring while chasing the Halcyon-class cruiser The Pillar of Autumn, but they did not know about the Flood, and did not expect interference from the UNSC. When High Charity and its fleet arrived at Threshold, they found that both Installation 04 and the Fleet of Particular Justice had been utterly destroyed.

In the early stages of the Battle of Earth, the High Prophet of Regret sent the coordinates of Installation 05 to High Charity. The planetoid and its fleet arrived just in time to watch Master Chief and a group of Marines assassinate the Prophet of Regret. It then held position over Installation 05 until hostilities erupted between the Sangheili and the Jiralhanae, as the Great Schism began in November 2552.

Battle of High Charity
During the chaos of the battle, John-117 infiltrated High Charity, by way of teleportation from Gravemind directly into the Council Chambers using Installation 05's teleportation grid.

At the same time, the Flood made their own entrance, using the to perform a slipspace jump into the interior of High Charity, bypassing its exterior defenses. Once inside, the Flood used Pelican dropships to spread both combat and Carrier Forms around the city. The Flood ravaged the Jiralhanae and Sangheili forces, who were already embroiled in conflict. John-117 was unfortunately caught in the middle of the battle, but managed to escape.

Eventually, the Dreadnought at High Charity's center took off, with both the Prophet of Truth and the Master Chief inside, leaving Cortana behind. Remaining Loyalist and Separatist forces either evacuated from the city (likely to be destroyed by the Sangheili quarantine fleet) or were consumed by the Flood, as they overwhelmed all remaining opposition in the city. The Gravemind took complete control of the Sanctum of the Hierarchs, using the High Council Chamber itself as his "throne room".

Quarantine of High Charity
As High Charity and Installation 05 rapidly fell to the Flood, a massive battle between Sangheili and Jiralhanae held ships continued in the space around the city. The Sangheili Separatists eventually succeeded in driving away the Jiralhanae or they possibly retreated on orders from Truth to assist in the conquest of Earth. But this led to the fall of High Charity to the Flood under the command of the Gravemind, who used this as his second base and gain significant amount of ships. He sent one infected cruiser to Africa, with the intent of infesting all of Earth.

The Sangheili fleet formed a large perimeter and quarantined High Charity and Installation 05, attempting to prevent the Flood from infesting any other systems. Presumably all Flood ships except one was destroyed, according to a Sangheili Major that was deployed to assist the Master Chief and the Arbiter. The pursuing Sangheili ships glassed parts of Africa to prevent further contamination.

After the Flood invasion
After the Battle of Earth, a message from Cortana notified the Master Chief that the Gravemind was speeding the infested High Charity toward Earth, and that the Portal leads to the Ark.

During the Battle of Installation 00 at the Citadel, High Charity appeared through the Portal and narrowly missed colliding with the Sangheili Assault Carrier Shadow of Intent. It disgorged Flood dispersal pods (one of which pierced the carrier) and crashed on the Installation. Covered with Flood biomass and with the interior transformed into a Flood hive, High Charity was almost unrecognizable.

Raid on High Charity
After stopping Truth from activating the rings, John-117 returned to the Flood-infested High Charity on a mission to retrieve Cortana. After successfully locating and retrieving her, he overloaded High Charity's backup reactor core and maneuvered back through High Charity to meet the Arbiter and re-activate a crashed Pelican dropship to escape the explosion. High Charity was completely destroyed in the resulting explosions, with only the outer structure remaining when Installation 04B was fired, its debris showering the inactive Installation and the Ark below. The Gravemind managed to escape, and immediately began re-building itself on Installation 04B.
