Huragok

Were you looking for Engineers, the Forerunner rate?

"A sentient labor-saving device with the ability to self-repair and self-replicate. Good with computers."

- Bungie.net description of Huragok

Huragok (Latin Facticius indoles, meaning "artificial genius" ), known to Humans as Engineers, are a race of biological supercomputers that were created by the Forerunners. They are the only known non-combatant race of the Covenant, though some are rigged to explode like suicide bombers.

Description
While it is generally held that only the San 'Shyuum are high enough in the Covenant Hierarchy to handle and manage Forerunner research and technology, in reality it is the Huragok who must excavate, unlock, and transport Forerunner artifacts (a fact only known to higher ranked officers and leaders within the Covenant, due to its sensitive nature), though the San 'Shyuum insist that any admission of that fact is heresy. These remarkably helpful and docile aliens are exceedingly patient, rarely communicate with other species, and are almost single-mindedly devoted to their work.

Huragok are the scientific and engineering backbone of the Covenant and its economy. They float via bladders that contain a mixture of gas lighter than air, and their four tentacles are able to split into many fine cilia, with which they are able to manipulate machinery on a near-microscopic level. Engineers are capable of quickly learning the functionality of new technology. On one occasion, an Engineer was observed by John-117 dismantling a vehicle's engine, assembling it into various other working configurations, and then returning it to its original state, all in a matter of seconds.

Huragok have little interest in taking sides in conflict; they appear to draw no real distinction between friend and foe, preferring to spend their time inspecting or repairing technology, although they will utter a high-pitched keening sound whenever a Forerunner artifact is under any sort of threat. They are apathetic to any sort of combat, and tend to just float along with a single goal: to fix things. In one encounter, a Huragok repaired John-117's damaged shield generator and then floated away; the rather unlucky Huragok was later shot by Lieutenant Haverson to prevent it from possibly giving the specifications of the Spartan's improved shield technology to the Covenant. If shot at in a firefight, Huragok make no attempt to defend themselves, but rather curl up in fright and float to a safe distance.

Their concentration has been described as "a trance-like reverie" by the few who have witnessed it. They usually communicate only with San 'Shyuum, a fact that may contribute to the balance of power between Sangheili and San 'Shyuum, and will usually ignore anything that is neither a San 'Shyuum, a Forerunner artifact, nor a machine. A notable exception is the Huragok Lighter Than Some, who communicated with the Unggoy Deacon Dadab via Huragok sign language.

The abilities of the Huragok are not limited to their skills to fix things; they are also able to absorb data from a computer or an A.I., and combine it with their own biological "data". One such incident occurred when one Huragok combined its knowledge with the dumb AI of New Mombasa, the Superintendent. During a mission to recover a living Huragok, Captain Veronica Dare described the species as "biological supercomputers".

Origins
The Huragok were created by the Forerunners prior to the first activation of the Halo Array. They served as "servant-tools" to the Builders, the highest rate in Forerunner society. They often served aboard semi-automated maintenance stations, including a number of facilities within the San 'Shyuum home system. They were rarely accorded personhood in Forerunner society.

Being mechanical structures rather than organic life forms, they survived the activation and were later found by the Prophets in various M-Series facilities.

The Covenant
After being discovered by the San 'Shyuum, the Huragok were employed as the Covenant's science, maintenance and archeological specialists. They were used to retrieve and dissect Forerunner artifacts, as well as to repair spacecraft and machinery. However, the actual amount of information that Huragok can extract is limited, and would require a more advanced artificial intelligence to assist in truly understanding the work of a Forerunner construct.

During various engagements in the Human-Covenant War, Huragok were deployed on certain human colonies to search for Forerunner technology. During the Battle of New Mombasa, they scoured the city for evidence of the Portal that lay beneath it's foundation.

Post-Covenant
After the dissolution of the Covenant, the Huragok dispersed, leaving the Sangheili at a loss without their mastery of technology.

Anatomy and physiology
The Engineers are actually not a natural, biological 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 observers. Multiple 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 small heads with 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, though they cannot survive in a vacuum.

Huragok are not normally a tactical threat and are hardly ever seen in combat situations. Most UNSC soldiers make a point of avoiding intentionally harming Huragok if possible. Unlike the majority of the Covenant races, they do not regard humans as enemies; during the John-117's assault upon Ascendant Justice, one even aided the SPARTAN-II by repairing the shield generator on his MJOLNIR armor and fixing the SPARTAN's current weapon, a broken Needler. However, Lieutenant Haverson killed the Engineer stating that it had learned all about the MJOLNIR shield technology, which was superior to the Sangheili Personal Energy Shield, and could not be allowed to relay that information. 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, which, against his wishes, was converted into the Brute Chopper.

Huragok "reproduce" by gathering the needed (or available) materials from their surroundings to "build" another Huragok. This new offspring is then filled with a precise mixture of lighter-than-air gasses. The initial buoyancy of the newly born Huragok is what it is named after. Three known Huragok names have been revealed so far. Those who sink are named 'Far Too Heavy'. Those whose buoyancy is almost perfect are named 'Easy to Adjust'. Lastly, those whose gas mixture causes them to exhibit extreme buoyancy are named 'Lighter Than Some'. 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 thirty minutes. Understandably, it is advantageous to have as many Huragok contribute to this process as possible, raising the "intelligence" of the offspring.

When deployed during large-scale archaeological expeditions, Huragok make use of large Recharge Stations, where they rest, repair each other, and share data between forays.

Huragok blood is luminescent blue-purple in color, as seen in Halo 3: ODST.

Huragok are bioluminescent, and in dark conditions their heads and tentacles emit a bright bluish glow, which seems to pulsate when the Huragok is calm and dim when it is frightened. The cilia on their tentacles give off a pinkish-red light as well.

Though the inner workings of an Engineer's internal macroscopic 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 painful, dangerous, and apparently only used as a last resort. In the Halo series, only one usage of the ability has been described: when 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 (particularly the more intelligent ones such as Dadab), 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.

Huragok can also communicate using melodic whistling sounds, as shown when Cortana used a Covenant SHIPCOM speakers to verbally communicate with a Huragok. This form of communication can also be heard in Halo 3: ODST and used in Halo Wars; the whistle sounds are how Huragok respond when selected. Their verbal communication is almost musical, and very slightly resembles the calls of Earth whales.

Personality
Huragoks 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, 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 the human, Henry Gibson, with a hunting rock.

Huragok have also been known to display great compassion and caring for one another, as shown in Halo 3: ODST. Dr. Endesha observed six Huragok selflessly give their own lives while attempting to disarm a bomb attached to another, which detonated after its removal and killed all but the seventh Huragok.

Halo Wars gameplay
In Halo Wars, Huragok provide the only means for the Covenant to repair damaged buildings, vehicles and heal injured units. They are easily slain as they are unarmed and can only be repaired by other Huragok - not by themselves. They do not attack and automatically search for damaged machinery, buildings and troops to heal and repair. Huragok create an almost unstoppable force when combined with the Scarab.

Symbols
"These tell stories, not very clear cut stories but they represent the shape of Forerunner ships, etc..."

- Joseph Staten, commenting on the symbols

Huragok are known to mark some areas of significance with mysterious glyphs, which can be found on various surfaces, walls, ceilings or floors, often in irregular patterns. These usually consist of an "Y"-shape or a circle, with various types of glyphs similar to Forerunner symbols around them. The symbols are likely related to the Huragok's Forerunner origin.

In Halo 3: ODST, they can be seen glowing with the VISR mode turned on. They are usually seen in or near areas of interest, such as locations with dead Sangheili or supply caches. The ones in the supply caches also bear similar symbols depicting the Superintendent, possibly hinting to cooperation of the AI with Huragok. This is further supported by the fact that the subroutine of the Superintendent known as Vergil fused with a Huragok to pass information along to the UNSC.

Behind the scenes
The creation of the Huragok started around 1999, during the development of Halo: Combat Evolved. From the beginning, they were meant to be "a class of aliens that acted as idiot savants towards technology," and were meant to be able to decipher Forerunner technology easily and allow a glimpse into what made the Forerunner technology so special. As far as gameplay, the designers wanted a race that were less aggressive to populate the world in a more passive way, making Halo feel more alive. The general idea of the Huragok was to be "a character meant to be passive, almost puppy like in nature," and make the players feel bad if they killed them.

Sea creatures were used for inspiration, especially underwater sea slugs and glowing jellyfish; their movements, the way they emit light, the fluidity of their bodies - and tried to translate that into a creature out of water. According to Shi Kai Wang, underwater sea creatures like the jellyfish had the right type of feel to them, a very docile and graceful creature that just minds its own business—very much how they initially wanted the Huragok to be. More emotive states were added to their animations and facial features to make them relatable, so that people would feel for them. The Huragok were eventually cut from Halo: Combat Evolved, as there was not enough time or technology to "make them feel right".

For Halo 3: ODST, the Huragok were completely redesigned to fit the gameplay, and to make them more in-depth characters. As the graphics, technology and capabilities were now available, the creatures could be made just like they were originally envisioned. Originally, in Halo 3: ODST, the Engineer was to suck its limbs and head into a cocoon shell and have it float away in distress or cower in fear. This effect wasn't fully achieved as a good solution for how the animations would work alongside gameplay couldn't be figured out. Eventually, the idea was turned into something similar but a scaled-down version.

Trivia

 * Engineers are the only Covenant race to be cut from the Halo trilogy and appear in later games.
 * In Halo 3: ODST, the "Good Samaritan" achievement can be unlocked by not killing any Engineers in New Mombasa at night during the entire campaign, alone or with another ODST. On the other hand, killing ten of the Engineers in the city will unlock the "Naughty Naughty" achievement.
 * In Midnight in the Heart of Midlothian, Mo Ye incorrectly states that the Covenant "call them Engineers". "Engineer" is actually the human name for the species, with the Covenant name being Huragok.
 * In Halo: Reach, it is possible to detach the face mask without killing the Huragok.
 * On the side of the Huragok's armored shell, there is a v-shaped symbol that bears a striking resemblance to the Noble Team logo.
