Huragok

Huragok (Latin Facticius indoles, meaning "artificial genius", ) known to Humans as Engineers, are an artificial race that was created by the Forerunners. They are the only known non-combatant race of the Covenant.

Summary
While the Prophets guide, direct, and manage Forerunner research and technology, they insist that it is heresy to admit that it is the Engineers caste who must excavate, unlock, and transport Forerunner artifacts. These remarkably helpful and docile aliens are patient, almost completely silent, and exceedingly reserved in their work and its religious implications. They are called Huragok in the Covenant language, and sometimes referred to as "Engineers" by the Humans, though there have been far less flattering terms for them.

Engineers are the scientific, engineering backbone of the Covenant and its economy. They float via air sacs and their many tentacles are able to split into many fine cilia, with which they are able to manipulate machinery. Engineers are capable of quickly learning the functionality of new technology. On one occasion an Engineer was observed by Master Chief dismantling a vehicle's engine, assembling it into various other working configurations, and then reassembling it the way it was, all in a matter of seconds.

Their motivations are unknown, but they appear to draw no distinction between friend and foe, preferring to spend their time inspecting or repairing technology, although they will utter a high pitched keening sound when a Forerunner artifact is under any sort of threat. They are extremely apathetic to any sort of combat, and tend to just float along with a single goal: to fix things. In one encounter, an Engineer repaired the Master Chief's damaged shield generator and then floated away; this Engineer was later shot by Lieutenant Haverson due to the risk of it giving the specifications of the Master Chief's improved shield technology to the Covenant.

Their concentration has been described as "a trance-like reverie" by the few who have witnessed it. They usually communicate only with Prophets (except in the case of Lighter Than Some, a Huragok from the novel Contact Harvest, who communicated with the Unggoy Deacon Dadab via Huragok sign language) -- a fact that may contribute to the balance of power between Elites and Prophets -- and will usually ignore anything that is neither a Prophet nor a Forerunner artifact, although they seem to have a general interest in all machines.

Some Engineers are used to help construct and repair the Covenant starships from the inside as part of the crew, and for this reason, there are some minor rivalries between the races of Huragok and Yanme'e. At least one Huragok has been killed as the result of a quarrel between the two groups.

In Halo Wars they appear as a support unit. Engineers heal or repair friendly units and buildings. This is the first time they appear officially in a Halo game.

Huragok are not picky eaters and they will help close friends as shown in Halo: Contact Harvest.

Engineer Anatomy and Physiology
The Engineers are actually not a species at all, but rather an artificial life form created by the Forerunners. While they possess no true tissues or organs, their nano-mechanical surrogates so closely mimic their biological analogs that they seem almost indistinguishable to lesser cultures. Gas-bladders serve as their method of locomotion, allowing them to float through the air even after their deaths. The bladders also serve as part of their respiratory system; if their gas bladders deflate, they will asphyxiate and die.

They have six dark eyes and four tentacles that can split into very small, near-microscopic cilia. The Engineers use these cilia to construct, repair, or rebuild nearly anything they can grasp. They can take apart whole vehicles and rearrange their entire structure in a matter of seconds, with the resulting machines still operating at least as well as they did before. They learn at an unprecedented rate, and store that information for future reference if ever they need to repair the same thing twice. They are capable of surviving in at least oxygen- and methane-rich environments, but they cannot survive in a vacuum.

Engineers are not a tactical threat and are hardly ever seen in combat situations. Unlike the majority of the Covenant races, they do not regard humans as enemies -- one even aided the Master Chief by repairing the shield generator on his MJOLNIR armor and repaired a broken Needler that the Chief was using during his assault upon the vessel Ascendant Justice. In Halo: Contact Harvest, a Huragok named Lighter Than Some attempted to aid the Humans in an attempt to bring peace; he even made them a peace offering, inadvertently making the Brute Chopper, which was based on a JOTUN, a human AI-controlled farming plow. Another Huragok repaired Master Chief's armor; as previously mentioned before, Lieutenant Haverson killed the Engineer, stating that it had learned all about the MJOLNIR shield technology, which was superior to the Elite's Personal Energy Shields, and could not be allowed to relay that information.

Huragok "reproduce" by gathering the needed (or available) materials from their surroundings to build another Huragok. Up to three Huragok take part in this process, relaying all the information that they have learned to their "offspring." Given sufficient raw materials, a pair of Huragok can produce a unified replica of themselves in approximately 45 minutes; the addition of a third Huragok cuts the time down to 30 minutes. Understandably, it is advantageous to have as many Huragok contribute to this process as possible, raising the "intelligence" of the offspring.

Huragok blood is colored a deep scarlet orange, and looks highly viscous and sticky. Piles of Engineer gore can be seen in the Halo Graphic Novel, whereupon the squad of Elites come across them inside the ship Infinite Succor. However, it is possible that this is not entirely accurate, as the graphic novel took several liberties with appearances.

Though the inner workings of an Engineer's internal biology remain a mystery, it is known that they are capable of using the gas sacks that keep them afloat for anaerobic respiration. This method is apparently only used as a last resort, and is unpopular among Engineers; in Contact Harvest, Lighter Than Some used anaerobic respiration to keep Dadab alive after the latter's methane tank depleted. Huragok use thousands of microscopic organisms to digest the food they consume, producing many gases, including methane, as a by-product.

Communication
Huragok can communicate with other Covenant species, such as Grunts, and perhaps with other Huragok, by flexing their limbs in various directions, bending and overlapping to form the specific formation for each word, much like Human sign language. Their gas sacs can also swell and deflate at times of great emotion, suggesting another, more subtle method of communication. Engineers can also communicate using whistle sounds, as shown in Halo: First Strike, when Cortana uses a Covenant SHIPCOM speakers to verbally communicate with an Engineer. This form of communication is used in Halo Wars; the whistle sounds are how Engineers respond when selected.

Origins
The Engineers were created by the Forerunners prior to the first activation of the Halo Array. Being mechanical structures rather than true life forms, they survived the activation and were found by the Prophets in various M-Series facilities.

Personality
Engineers are an extremely valuable asset to a crew as they enjoy fixing things immensely. In several of the novels, they are described as caring about nothing else. However, in Contact Harvest, it is shown that they are very peace loving and have a great respect for life in general. Lighter than Some even refuses to play a game that would kill non-sentient pests. However, they can be pushed into violence when a friend is in danger, as demonstrated when Lighter than Some saved his friend Dadab by killing a human, Henry Gibson, with a hunting rock.

==Appearances== Engineers are seen in Halo: The Fall of Reach, Halo: First Strike, Halo: Ghosts of Onyx, Halo: Contact Harvest, Halo 3: ODST, The Art of Halo and Halo Wars.

In Halo: The Fall of Reach, an Engineer is observed by the Master Chief dismantling and re-assembling a Human car on Sigma Octanus IV. This was their first, known recorded appearance by the UNSC. This also demonstrated their knowledge of machines, no matter the type.

In the Halo Graphic Novel it is noted that some Engineers were stationed on the Infinite Succor. Rtas 'Vadumee noted that the Flood had killed Engineers, smearing their blood onto the floor, which proved that it was not Human forces that had infiltrated the Infinite Succor, but something else.

In Halo: First Strike, an Engineer repaired the Master Chief's Needler. Later another one repaired his Energy Shield; this one was fatally shot by Lieutenant Haverson, to avoid the risk of it divulging the MJOLNIR's improved shield design to the Covenant. Haverson appeared to feel some pity for the creature. Due to its mechanical nature, however, it may have simply been repaired by another Engineer.

In Halo: Ghost of Onyx, a group of Engineers repaired a NOVA bomb stolen by the Covenant fleet after a Grunt, Kwassass pushed a button. The NOVA bomb was then activated and exploded, destroying the Covenant super-carrier Sublime Transcendence and its entire crew, as well as the nearby Covenant outpost planet Joyous Exultation, its moon, Malhiem, and the rest of the fleet orbiting it.

Engineers were originally intended to appear in Halo: Combat Evolved, but due to time constraint issues, they were "left on the cutting room floor." They were cut so late, however, that they remained in the Prima Guide for the game, and their files were not deleted entirely from the game -- modders have located the Engineer files on the game disc and spawned Engineers in various configurations, hence the images that may be found.

Here is a video demonstrating such a mod.

Engineers are also featured in the Bestiarum booklet in the special editions of Halo 3, though they do not appear in that game either.

A Huragok, Lighter Than Some, appears in the book Halo: Contact Harvest. He is shown to have a fairly friendly relationship with shipmate Dadab, a Grunt Deacon.

Many conceptual designs for the Huragok appear in The Art of Halo.

Huragok in Halo Wars
In Halo Wars, they provide the only means for the Covenant to repair their damaged buildings and vehicles and heal injured units. They are easily slain, as they are unarmed and can only repair other Huragok -- not themselves.If combined with a Scarab and another engineer they will make the scarab almost indestructible.They'll automatically search and find damaged machinery and troops to repair. They have two upgrades:
 * "State of Grace": allows Huragok to have faster repair rate.
 * "Harmonious Digestion": enhances their movement speed..

They are trained from the Summit, require 250 resources and 0 tech level, and count as 1 population. They somewhat resemble Flood Bomber Forms, though not in size.

Naming
The Huragok (Engineers) are named by their parents depending on their initial buoyancy. The parents of the Huragok find the right mix of gases and then give their name depending how well they float, for example: Lighter than Some; Easy to Adjust; Far too Heavy.

Trivia

 * Engineers are the only Covenant race to be cut from the original Halo Trilogy yet still considered "canon", as they appear in the novels. They were later included in Halo Wars. Though they were cut from Halo: Combat Evolved, the Huragok went through several development cycles.
 * Halo fans first learned of the Huragok from a screenshot in the August 2000 issue of PC Gamer magazine (scanned here).
 * If a Huragok is killed after being modded into Halo: Combat Evolved, it will simply remain perfectly still, as it has no death animation. If you shoot it after the blood has spilled from it, the skin of the Huragok will bubble with a purple liquid where you shot it, which shows an element of Halo: Combat Evolved that was never used in the final game - wound graphics.
 * Because of their "mechanical gifts", it is possible they could have been created to replace or supplement the Constructors as the Forerunners' "repairmen".
 * An image of a Huragok can be seen in the Halo: Combat Evolved Prima guide, next to the profile for the Flood Infection Form.
 * Huragok have a minor resemblance to the Flood Carrier Forms.
 * Huragok do not care who their allies or enemies are; they simply want to do their job.
 * Three Huragok were taken prisoner aboard the Ascendant Justice when it was captured by Human survivors of the Battle of Installation 04. One was killed after it learned of Human shield improvements, to prevent its return to the Covenant. The other two were presumably interrogated by ONI. Their current fate remains unknown.
 * An Engineer is credited with saving the Master Chief's life in First Strike.
 * The Huragok are, ironically given their pacifism, the species credited with killing the first human in the Human-Covenant War, albeit accidentally. This particular Huragok was Lighter Than Some, who killed a man on board the ship This End Up by throwing a "hunting rock" at the back of his head, killing him instantly.
 * Huragoks and Lekgolo are the only known species to have been named by the Forerunners.
 * Despite looking and fitting in the Covenant armada, the Huragok is actually a Forerunner creation.
 * Huragok made their first in game appearance in Halo Wars, despite having existed in canon since The Fall of Reach.
 * Engineers are known for being neutral. In Halo Wars, they will repair or heal both Covenant and UNSC units, though only if they are on the same team.
 * Besides the Flood and other Forerunner constructs, the Huragok are the only living proof of the Forerunners' existence.
 * The noise made by Engineers when selected in Halo Wars is similar to Clanger-speak, the whistling voices of the Clangers in the BBC childrens' television series of the same name.
 * In Halo Wars, Huragok have the ability to repair infantry, structures, and vehicles. However, the "repair" process when used on squads may appear somewhat illogical since rather than healing only the wounded remaining member(s) of the squad, the Huragok regenerates the deceased members of the squads out of nothing. This most likely due to segregation of gameplay and lore.
 * In Halo 2's Conversations From The Universe they are known to be called "Loogies" or "Boo-Bags" for their appearance.
 * Engineers appear in Halo 3: ODST as a killable enemy bomb.
