"I have led you, my Prometheans, for thousands of years, and I shall continue to lead you. Rise! Rise, and protect the Forerunners! Rise, and protect the galaxy!"
— The Didact to his legions of newly created Promethean Knights[5]

Promethean Knights are a class of armiger, or mechanised Forerunner warrior, created by the Ur-Didact toward the end of the Forerunner-Flood war to combat the Flood. They are named for their origins in the Prometheans, one of the highest and most well-respected groups in the rate of Warrior-Servants; the first Promethean Knights were created by composing the Forerunner Prometheans, sublimating their consciousness into robotic form in the hopes of creating an infantry force that would be immune to Flood infection. Despite this, there were still too few Promethean Knights to make a meaningful difference in the progress of the war, leading to the Didact instead turning the Composer on ancient human populations and creating an army of beastial machine-soldiers enthralled into his service.[3]

After the Librarian exiled the Ur-Didact on Requiem for this act, several legions of these constructs stationed on the shield world went dormant for the next 100,000 years. The machines—as well as their master—were reawakened in late 2557, when John-117 and the United Nations Space Command stumbled upon Requiem.[6][3] By 2558 they, along with several other Promethean constructs, had fallen under control of the Created led by Cortana, who believed the artificial intelligences were the rightful heirs of the Mantle of Responsibility, not humanity.[7]

Overview[edit]

Design details[edit]

The Promethean Knights are bipedal, fully weaponized mechanical warriors designed to operate and eliminate threats in a wide variety of environments.[6] While the Knights are fully machines, their AI is a result of organic minds transformed into software format via a device called the Composer, unlike the Crawlers or the sentinels which are completely artificial in origin.[2] Similar to the other Promethean constructs, as well as some earlier types of Forerunner military automatons,[8] Knights have a number of insectoid attributes; they produce noticeably insect-like clicking sounds and tend to make spasmodic movements, especially when idle. Additionally, their carapace resembles that of an insect and possesses hatches resembling insect wings which frequently twitch and flutter seemingly at random; located on the "wings" are the Knight's anterior shield distributors.[2] Knights have two sets of arms; two large, artificial arms at each shoulder in which the weapons are mounted and two smaller arms below the shoulders. The larger arms are composed of separate segments held in formation through an energy field. Knights also have a comparatively smaller set with small, five-fingered hands. These smaller arms are more "organic" in shape and are physically attached to the Knight's body. Their main locomotion is provided by a pair of extremely powerful legs designed for agility and speed. Broad-set stabilizers support the large body and reinforced joints offer fluid movement despite the Knight's size and mass. At the back of their feet there is a counter-locking system for tactile balance.[2]

Knights are remarkably agile, and in addition to using their limbs for conventional movement they are also capable of translocating over moderate distances, allowing them to either swiftly retreat from the battlefield or to flank their enemies. Although not commonly seen in the field, Knights can also be deployed from warships and are equipped with thruster engines on the sides of their carapace for maneuvering. This capability was used near the end of the Forerunner-Flood war, when Knights were deployed to board and destroy Flood-controlled ships from within.[9]

The Knight's carapace is composed of smartmatter, a form of programmable matter held together by hard light bonds.[4] Upon taking critical damage, Knights completely disintegrate, a process that Cortana described as a "data purge."[10] Their bodies erode away from where the fatal shot was received and dissolve into glowing particles. After disintegration, a small ball of swirling light is left behind for a brief period; a Promethean Watcher can use this remnant to recreate and revive the Knight; however, an individual Knight can only be revived in this manner only once. If a Knight is destroyed, revived, and then destroyed again, the Knight's body disintegrates completely, leaving nothing behind. When a Knight is destroyed, it drops a weapon; after revival, it wields a weapon of the same type even if the first weapon was picked up.[11]

Knights are covered in patterns of light and have a fire-like glow around their heads. The color of this light usually indicates their allegiance. Those with blue lights are controlled or otherwise loyal to the Librarian or her remnant;[12] upon the Didact's release from his Cryptum the Knights' color changed to orange, indicating they had returned to his control.[10] The head features an armored helmet with glowing eyes and what appear to be grimacing jaws with rows of teeth. This helmet assembly can be retracted in two sections, revealing a glowing humanoid skull underneath.[11] Cortana initially theorized that this is because the Prometheans have mimetic capabilities, and had based the skull on scans taken of the Master Chief, though the skull may in fact be based on that of a Forerunner.

Knights carry a single Promethean Watcher sentinel in the back of their armored carapace, which can be deployed at will for combat support. The Watcher's AI is a low-level ancilla split off from the Knight's essence when the Watcher is deployed.[2] The Watcher can greatly improve the Knight's combat capabilities by raising hardlight shields, reviving fallen Knights, summoning Crawlers, building automated turrets, and flinging back enemy grenades while distracting them with its own weaponry.[11]

Creation[edit]

Unlike armigers and sentinels, Knights are not artificial intelligences, even despite their robotic exterior. They instead consist of a sapient mind converted into a software form by a Forerunner device known as the Composer. The conversion process is called sublimation, and is something the Forerunners never truly understood. The results of the Composer's work are essence imprints akin to high-level ancilla, with stored mentalities that are capable of being given individual localised consciousness by replicating their original brain's neural structure.[1] The digitised essences are stored in the Composer's Abyss
