'''Forerunner Sublimation Device'''<ref>'''[[Halo 4: The Essential Visual Guide]]''', ''page 132''</ref>, more commonly known as '''Composers''', were ancient [[Forerunner]] machines capable of converting living beings into digital forms.<ref name="h4">'''Halo 4'''</ref> The scheme was among the first of the countless plans laid by the Forerunners to defeat the [[Flood]].<ref name="string3">'''Halo: Silentium''', ''String 3''</ref>

==Overview and function==

After the [[Forerunner]]s first discovered the existence of the [[Flood]] parasite in the later stages of the [[Human-Forerunner War]], the Forerunners quickly began to devise plans to combat the infection should it resurface. The Composers were one of the first solutions proposed by the [[Builder]]s. The original function of the machines was to save Flood victims by extracting their mental patterns - or essences - and translating them to data by broadcasting high-energy fields of entangled sympathies. The stored essence would then be imprinted on a new, artificially constructed biological body devoid of Flood infection. However, the process was highly flawed. All attempts to restore the essences to biological form failed as the artificial bodies would quickly decay and inevitably die.<ref name="string3"/> For this reason, the Forerunners quickly abandoned the Composers after the first experiments.<ref name="pri271">'''Halo: Primordium''', ''page 271-272''</ref>

Despite the failure of the original plan, the Forerunners found other uses for the Composers. Although the Forerunners possessed other technologies capable of extracting an individual's memories and personality impressions,<ref>'''Halo: Cryptum''', ''pages 47-48, 138''</ref> only Composers were given to the [[Librarian]] and her [[Lifeworker]]s when they were tasked with extracting the essences of the human survivors on [[Charum Hakkor]]; powerful forces in the [[Ecumene Council|Old Council]] - mainly Builders - wanted to make sure the fate of their enemies would be as cruel as possible.<ref name="string3"/> The Librarian implanted these stored personalities into the genetic code of living humans, with said personalities achieving self-awareness and retaining their original identity within their new [[human]] hosts, such as [[Chakas]] and [[Riser]]. The Composer could also be used to remove these imprinted personalities, although this did grave physical and mental damage to the individual carrying the imprint.<ref name="p355">'''Halo: Primordium''', ''page 355''</ref>

The Composer did not work on all organic beings; certain individuals could, through genetic manipulation, become immune to its effects. After undergoing and experimental [[Forerunner mutation|mutation]] in an attempt to gain immunity to the Flood, the Ur-Didact's physiology was no longer compatible with the Composer.<ref name="h4terminals">'''Halo 4''', ''[[Terminal/Halo 4|Terminals]]''</ref> Similarly, the ''[[geas]]'' the Librarian placed on humanity allowed the [[SPARTAN-II Program|Spartan]] [[John-117]] to develop a resistance to the Composer; this ability had to be activated, and thus it did not automatically protect all humans from the device.<ref name="reclaimer">'''Halo 4''', campaign level ''[[Reclaimer (level)|Reclaimer]]''</ref>

The physical effects of the Composer on its targets appear to have been varied; when the [[Ur-Didact|Didact]] fired the Composer directly on humans, the device projected a beam of orange light which completely reduced the targets to ash in a rather gruesome and painful manner while their minds were digitized. Aside from this direct form of scanning, the Composer was also capable of a less violent method of extraction. When the Librarian and her [[Lifeworker]]s used the Composer indirectly via intermediary devices, the bodies of the targeted individuals were not destroyed and instead the scan caused them to expire as their consciousnesses were removed from their bodies.<ref name="p235">'''Halo: Primordium''', ''page 235''</ref>

Minds scanned by the Composer could be processed in a variety of ways. Although the ancient human personalities extracted and stored by the Librarian were retained in their original essences, in some cases the digitized neural map could be used as the basis for [[artificial intelligence]] constructs in a manner similar to the creation of human [[smart AI]]s. These intelligences would contain many of their original memories and sometimes even portions of their personality, but would otherwise behave within the limits of the duties assigned to them. For example, the [[Promethean Knight]]s behave in a largely uniform manner despite containing at least some of the memories of the individuals they were created from.<ref name="memento">'''[[Spartan Ops]]''', ''[[S1/Memento Mori|S1E5 ''Memento Mori'']]</ref>

The Composer could, by working in tandem with other technologies, slow down Flood infection and the subsequent loss of individuality. However, this process was only temporary and still left the afflicted individuals in their deformed state. This was accomplished through wrapping the infected bodies in a form of supportive harness flowing with energy, which evidently prevented the Flood from subsuming the consciousness of the victim - at least for a time.<ref>'''Halo: Primordium''', ''page 322-323''</ref> Inevitably, victims preserved in this way would eventually expire or succumb to infection.

==History==
Composers were given by the Council to the [[Librarian]] and the Lifeworkers to extract the memories of the surviving [[prehistoric human civilization|human]] warriors after the [[Charum Hakkor campaign]]. These personalities would be preserved in future generations of humans, with the intent that they share their knowledge with the devolved remnants of humanity and aid them in re-building their civilization. The Master Builder and other like-minded Forerunners intended to study the stored memories in hopes of discovering how humanity managed to [[Human-Flood war|defeat the Flood]]. The [[Forthencho|Lord of Admirals]], the supreme commander of all human forces and one of the humans to have their minds harvested, described the effects of the Composer as "strange, ever-changing" and "multiformed", as it operated via intermediary [[Lifeworker]] machinery.<ref name="p235"/>

As a result of the risks and irregularities involved with their usage, the Forerunners eventually abandoned the Composers and their existence was made a closely guarded secret known to only a few.<ref name="pri271"/> Even the fact that there were once many Composers was unknown to most by the time of the [[Forerunner-Flood war]], with the general assumption being that only a single Composer ever existed. Even the machines' actual nature remained obscure; whether it was a machine or being remained uncertain to most. Some even believed the Composer to be a "product of its own services"; a Forerunner, perhaps a Lifeworker, suspended in the final stages of Flood infection.<ref name="p268">'''Halo: Primordium''', ''page 268''</ref><ref>'''Halo: Primordium''', ''page 278''</ref>

[[File:H4-ComposerFiringOnPhoenix.jpg|right|250px|thumb|The Composer firing on the city of [[New Phoenix]] on Earth.]]

Around [[100,000 BCE]], the Composer was used by [[Master Builder]] [[Faber]] to stave off Flood infection in certain Forerunners on [[Installation 07]] to keep them in a docile state. While in control of Installation 07, [[05-032 Mendicant Bias|Mendicant Bias]] and the [[Primordial]] also used the Composer to extract the ancestral memory imprints from [[Chakas]] and the other humans from [[Earth|Erda]].<ref name="p355"/> Later during the [[Forerunner-Flood war]], the [[Ur-Didact|Didact]] used the Composer to convert his [[Promethean]] warriors into [[Promethean Knight|robotic forms]] to allow them to combat the Flood more efficiently and without risk of infection. To bolster his numbers, the Didact used the Composer on a number of humans transplanted to [[Omega Halo]], turning them into additional forces in his mechanized army.<ref name="h4terminals"/>

The Composer was later placed on Halo [[Installation 03]]. In late [[2554]],<ref>'''Halo 4''', campaign level ''[[Composer (level)|Composer]]'', [[Halo 4 audio logs|audio log]]''</ref> the [[United Nations Space Command|UNSC]] [[Office of Naval Intelligence]] discovered the machine on the Halo ring and transported it to [[Ivanoff Station]], a research facility in the asteroid field in Installation 03's orbit. The machine was partially buried within the installation's surface and remained embedded in a large chunk of rock when the UNSC transported it to Ivanoff. Some of the scientists were digitized by the Composer while studying it and the sensor data from the incident contained coordinates that led the {{UNSCShip|Infinity}} to [[Requiem]].<ref>'''Halo 4''', campaign level ''[[Infinity (level)|Infinity]]''</ref> Upon awakening on Requiem in [[2557#July|July 2557]], the Didact immediately headed for the Composer and acquired the device after [[Raid on Ivanoff Station|launching an attack]] on Ivanoff Station. Planning to use the Composer to neutralize all of mankind by forever imprisoning them into digital form, he first used it on the human personnel of Ivanoff; Spartan [[John-117]] was the only survivor as a result of genetic modifications imbued by the Librarian. The Didact then set course for Earth in order to realize the final stage of his plan. He successfully fired the Composer on a [[United Republic of North America|URNA]] metropolis, [[New Phoenix]], but the effect was halted when John-117 destroyed the Didact's ship, and the Composer along with it, with a [[HAVOK tactical nuclear weapon]].<ref name="h4"/> Some of the resulting digital intelligences survived, having ended up on Requiem via a slipspace transit portal connected to the Composer.<ref name="memento"/>
