Huragok

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

Summary
While the Prophets guide, direct, and manage Forerunner research and technology, though the Prophets insist that it is heresy to admit it, it is the Engineer 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 tasks and its religious implications.

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, reassembling it into varying different working configurations, and then reassembling it in the way it was, all in a matter of seconds. They are called Huragoks in the Covenant language, and sometimes referred to as "Engineers" by the Humans, though there have been far less flattering terms for them.

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 will just float along with their one desire: 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.

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.

Engineer Anatomy and Physiology
The Engineers are actually not a species at all, but rather an artificial life form created by the Forerunners. However, 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. Their method of locomotion is to float using gas-bladders, even continuing to float when dead. Indeed, 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, and it will still operate as it did before, or better. 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 cannot survive in a vacuum.

Engineers are not a tactical threat and are hardly ever seen in combat situations. They do not regard humans as enemies, and even aided the Master Chief by repairing his shield generator of his MJOLNIR armor and repaired a broken Needler that the Chief was using in his assault upon the vessel Ascendant Justice. This is also shown in the novel Halo: Contact Harvest when a Huragok named Lighter Than Some was aiding 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 John's armor, and as previously mentioned before, Lieutenant Haverson killed the Engineer, stating that it had learned all about the MJOLNIR shield technology that is superior to the Elite's Personal Energy Shields and could not be allowed to relay said information.

Huragoks "reproduce" by gathering the needed (or available) materials from their surroundings and build another Huragok. Two or three Huragoks take part in this process, relaying information they have learned to their "offspring." Understandably, it is advantageous to have as many Huragoks contribute to this process as possible, raising the "intelligence" of the offspring.

The blood coloration of the Engineers looks a deep scarlet orange. 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. The blood also looks highly viscous and sticky. However, it is possible that this is not entirely accurate, as the Graphic Novel took several liberties with appearances.

Though the Engineer's internal biology is little known, they are capable of using the gas sacks that keep them afloat for anaerobic respiration, using thousands of microscopic organisms to digest the food they consume, producing many gases, including methane, as a by-product. This method is apparently only used as a last resort, and is unpopular among Engineers. In Contact Harvest, the Huragok, Lighter Than Some, used anaerobic respiration to keep the Unggoy, Dadab, alive because his methane tank depleted.

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 the Human sign language. Their sacs can also swell and deflate at times of great emotion, suggesting another, more subtle method for communication. Another form of communication is possible, evident in the book Halo: First Strike, when Cortana uses a Covenant SHIPCOM speakers to verbally communicate with an Engineer, via whistle sounds. This form of communication is continued in Halo Wars as the whistle sounds are how they respond when selected.

Origins
The Engineers were created by the Forerunner prior to the first ring activation. They survived the activation and were found by the Prophets in various M-Series facilities. Though still sentient creatures, able to reproduce and communicate, Huragok are in truth constructs apparently created using advanced nano-technology by the Forerunners. They possess no true tissue or organs, but can mimic them so closely they are indistinguishable from their biological analogs. Given sufficient raw materials, a pair of Huragok can produce a unified replica of themselves in approximately 45 minutes. A maximum of three Huragok may participate in the reproduction event, the subsequent time for creation of an offspring is cut down to 30 minutes. The latter method is preferred, because the new engineer is given all experience possessed by the Engineers taking part in the production of the new Engineer, the Engineer being produced will receive a wider range of experience, making the Huragok extremely knowledgeable.

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 we see when Lighter than Some saves Dadab from Henry Gibson.

Appearances
Engineers are seen in Halo: The Fall of Reach, Halo: First Strike, Halo: Ghosts of Onyx, Halo: Contact Harvest, 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, then later another one repaired his Energy Shield and was later shot by Lieutenant Haverson, because it presented the risk of divulging the MJOLNIR's improved shield design to the Covenant. Haverson appeared to feel some pity for the creature. However, in light of information provided by the Bestiarum, it would seem that there is a possibility that it was 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 with its entire crew including Kwassass, as well as the nearby Covenant outpost planet Joyous Exultation and 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, Engineers were "left on the cutting room floor." But they were not deleted entirely from the software, and modders have since located the Engineer files on the game disc and spawned Engineers in various configurations, hence the images that may be found. Other than this, Covenant Engineers are never seen in any of the Halo games other than Halo Wars.

Engineers were cut from Halo: Combat Evolved so late, that in the Prima Guide to Halo: Combat Evolved, a picture of an Engineer can actually be seen next to the profile on the Flood Infection Form. Also they can be seen in Halo: Combat Evolved by way of a mod in the level The Silent Cartographer. (As seen in photo at right)

Here is a video demonstrating such a mod.

Engineers are also featured in the Beastiarium 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 are the only way for the Covenant to repair their damaged buildings and vehicles and heal injured units. They can be easy to kill since they're unarmed and will be able to repair other Huragoks but not themselves. They'll automatically search and find damaged machinery and troops to repair. They have two upgrades:
 * "State of Grace": allows Huragoks to have faster repair rate.
 * "Harmonius Digestion": enhances their movement speed..

They are built inside the Summit, require 250 resource points and no tech level, and count as 1 population.

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 cut from the original Halo Trilogy still considered "canon", as they appear in the novels. Eventually they were included in the game Halo Wars.
 * Though it was cut from the final game, the Engineer 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 in to 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 Forerunner's "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 in case it managed to return to the Covenant, bringing with it Human energy shield improvements. The other two were presumably interrogated by ONI. Their current fate remains unknown.
 * An Engineer is credited with saving Master Chief's life in First Strike.
 * The Huragok are 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 the man's head, killing him instantly.
 * Huragoks and Lekgolo are the only known Forerunner-named species.
 * Huragok make their game debut in Halo Wars, despite having existed in canon since The Fall of Reach.
 * Huragok were not included in Halo:The Flood.
