Library
From Halopedia, the Halo wiki
The Library, known to the Covenant as the Repository of Fate,[1] is the name given to a structure present on the installations of the Halo Array.[2][3] The Libraries are vast archive complexes and research facilities,[4] housing the collated genetic information of numerous sentient species indexed by the Lifeworkers during the Conservation Measure, an effort to re-seed life in the galaxy following the activation of the Halo Array. The structure also houses the Activation Index, the object used to activate the Halo ring and simultaneously initiate the repopulation process of the species archived in the Library.[5] Library facilities are not exclusive to the Halos and are found on several other installations as well.[4]
Background[edit]
Located at the heart of the Library is a multi-tiered hall known as the Index chamber, in the center of which the Activation Index is suspended. In accordance with proper Flood containment procedures, the Reclaimer tasked with activating the Installation must first deactivate an energy field surrounding the Index by accessing a large elevator on the Library's uppermost floor. The elevator then descends from the highest level of the Library to the Index's position, allowing the Reclaimer to retrieve it from its container. Also according to procedure, the Reclaimer's passage through the Library is assisted by the Installation's monitor, whose duties also include opening the facility's various security doors.[2]
The interior of a Library consists of multiple gigantic hallways of geometric design interconnected to one another, all surrounding the Index chamber. Massive security doors are located between each section. Other floors of the structure are accessed via large, circular elevator platforms. Like most structures on the Halo rings, a Library also houses a network of ducts and shafts used by the Sentinels or the installation's monitor to access other areas. During the Flood outbreaks on Installation 04 and Installation 05, the Flood were able to utilize these tunnels to move across the structure.[2][3]
Due to its crucial importance, the Library is the first target of the Flood parasite during an outbreak. As a security measure against the Flood, most Libraries are separated from the rest of the installation by various types of obstacles, such as moats, chasms or massive walls.[4] Access to the Library itself usually occurs via each installation's internal teleportation grid.[2] On Installation 05, 2401 Penitent Tangent was unable to assist the individuals wishing to retrieve the Index in this manner. As a result a longer, less direct route had to be taken. An anti-gravity gondola spanned a large chasm separating the installation's Quarantine Zone from the Library.[3] The quarantine zone was encircled by the Sentinel Wall, a massive barrier which was protected by a containment shield and filled with numerous Aggressor Sentinels and Enforcers.[6] On both Installation 04 and Installation 05, the Flood was still able to breach such defenses and infest the Library.
History[edit]
Installation 04[edit]
After meeting Marine Staff Sergeant Marvin Mobuto and deeming him to be a Reclaimer, 343 Guilty Spark translocated him to the Library of Installation 04 and instructed him to retrieve the Index. However, Mobuto was ill-equipped for the sheer number of Flood that he faced and was overwhelmed, ultimately committing suicide to avoid infection.[7][8][9]
Next, after meeting John-117 in the swamps near Installation 04's Flood containment facility and deeming him to be a Reclaimer, 343 Guilty Spark translocated the Spartan into the Library of Installation 04 and instructed him to retrieve the Index.
The Flood had heavily infested this Library in the few short days since their initial breakout, with large groups using the ventilation shafts and access corridors to make their way through the facility. There were Flood in almost every part of the complex, including the Index chamber itself, and the Sentinel drones assigned to the facility were mostly overwhelmed. By the time the Chief arrived, the Sentinels were reduced to small groups using the shafts to avoid destruction and the Flood had begun spreading their spores through the facility by using the ducts. In addition, the concentration of biomass and Flood blisters increased the further he descended.[10] It seems the Covenant made no attempt to access the Library on Installation 04. While the Master Chief explored the dark bowels of the structure, there was no sign of the usual crates, stationary shield generators or spare weapons.[2]
As the Spartan progressed through the Library, 343 Guilty Spark remarked upon both the nature of the Flood and the Forerunners. Making a specific reference to their technological superiority, he wondered why the Chief had brought "such ineffective weapons to combat the Flood". Guilty Spark also recommended that the Master Chief should upgrade from his Mark V MJOLNIR armor, which according to a Forerunner ranking system was only Class 2 to a Class 12 combat skin, which was stated as a necessity in order to combat the Flood. However, he later told the Master Chief that his suit would serve him well as the Flood began to contaminate the ring's atmosphere with Flood spores.[2]
Toward the end of this Library, the Chief encountered the body of Mobuto who Guilty Spark had previously approached and brought to the Library in order to retrieve the Index and activate the ring.[9] With help from the Sentinels, and motivation from Mobuto, the Master Chief fought his way through three levels of the complex and successfully retrieved the Index.[2]
Installation 05[edit]
While the Master Chief hunted down the Prophet of Regret during the Battle of Installation 05, Commander Miranda Keyes, Sergeant Johnson and most of UNSC In Amber Clad's Marines attempted to break into the Library of Installation 05 in order to find and retrieve the Index. Due to the significantly larger Flood outbreak on this Installation, the Library and its defenses were seriously damaged and as a consequence were filled with a larger number of Flood than its Installation 04 counterpart. The UNSC forces were seemingly unprepared for the Flood presence, and many of them were infected by the Flood.[3]
Around the same time, the recently-appointed Arbiter Thel 'Vadam traveled to the Library on a mission to retrieve what the Covenant referred to as the "Sacred Icon". Dropped into the exterior side of the Sentinel wall from Tar
