Eiraghases (plural for Eiraghase) are a petrophagous akriid species native to Gorb Olohya.


Eiraghases originated in the satellite Gorb Olohya. Their role to the sapient inhabitants of the moon is unknown.

Eiraghases were one of the main obstacles to Llurebleg explorers Zano Hylera and Nynn Vandar during their expedition to the satellite, with one individual bringing a flock of Ghinghases upon them.



Eiraghases are massive creatures, easily towering up to 30 meters in height, but usually measuring little more than 16 meters. They are also quite long, measuring up ti 20 meters in lenght; they are, however, very light, weighing from 60 to 100 kilograms.

Ghinghases have a short ovoid body partially covered in a exoskeleton and with a short tail. It has only two limbs, which are long bony legs, representing the majority of the creature's height. These legs end in long and thin insectoid feet. Their head is composed of a bottom jaw, which is bony and leads to a large vent that acts as the mouth; three proboscis-like structures, which serve for different purposes; and a large helium sack slightly resembling the crest of a Terran Parasaurolophus, allowing the Eiraghase to lift its body up. Eiraghases are covered by dark grey scales, although pitch black individuals are known to exist.

There is no certain sexual dimorphism between the Eiraghase's genders. It is thought, however, that the black individuals are actually the males, as they are the ones most frequently found with children. Young Eiraghases are extremely similar to their parents, with no known visible differences between adults and infants.

Traits and abilities[]

Eiraghases, despite being massive creatures, lack muscular strenght and rely on their helium sacks to stand upright. They aren't exceptionally fast nor agile either. Their backs, legs and jaws have bony protection, but the scales that cover the rest of their body don't, making them quite fragile as well.

Eiraghases are most notably known for their gargantuan height, which is mostly represented by their long legs. This size is useful for intimidating most predators, while keeping their vulnerable, unprotected parts out of their reach. The Eiraghase's three proboscides serve different purposes: the two upper proboscides in its head are constantly sucking air (including steam and helium) and expelling carbon dioxide, serving for breathing, for obtaining water and for regulating the amount of helium inside the sack on its head; the lower proboscis can spew out a strong acid substance capable of melting through stone and presumably metal, while not harming the Eiraghase's insides due to strong, inner bony protection, the acid serving the purpose of melting rock in order to make it edible for the creature, similarily to Earth's flies.


In the monotonous enviroment of Gorb Olohya, Eiraghases have no home to choose but the flatrock plains that, together with a dense bluish mist, cover the whole planet, to which they had to adapt in order to obtain food and water.


Eiraghases only interact with each other when reproducing and taking care of their cubs, but they aren't lonely creatures by any chance. They have established a rather essential symbiotic relationship with the Ghinghases: the Eiraghase, as it has no eyes, is completely blind, and need to use echolocalization to detect its surroundings. Also uncapable of producing sound by itself, it relies on the Ghinghases' guiding them with their constant screeching. The Ghinghases also repell the Eiraghase's parasites, such as Vigecataro, and take care of their cubs. In exchange, the Eiraghase lets the flock live on its back, and unvoluntarily takes them to herds of prey for them to hunt.

When most of the Ghinghases on the "host" divise a herd of prey (usually Arzhraghases), the Eiraghase will proceed to eat, always guided by some remaining Ghinghases. Ghinghases are petrophagous: they feed on rocks. In order to eat, the Eiraghase will release acid substances using its lower proboscis to melt the rock under it; then, monitores by the Ghinghases, it will release some helium from its head in order to bow down. and submerge its jaw in the liquified rock, sucking it with its "mouth". It will then reabsorb helium in the air in order to lift up, and repeat the process until the Ghinghases are done feeding.

Eiraghases, unlike other creatures in Gorb Olohya, have defined reproduction periods: every 50 Gorb Olohyan days, Eiraghases will start producing hormones to attract members of the opposite sex. If they don't find a mate five days after the hormones start being released, they will stop producing and wait another 50 days to repeat the process. When finding a mate, they the female will lay an egg and the male will fecundate it externally, similarily to Earth's chickens. One of the two members (usually the male) will incubate the egg and take care of it, not producing more hormones until the cub is old enough, while the other one will leave and wait another 50 days to produce hormones. During all this time, the Ghinghase flock on the parent won't be able to hunt for a long time, causing some individuals to leave and look for another flock. After incubating the egg for another 50 days, the cub will hatch and the parent will move again together with its child, as Eiraghase infants are born capable of walking. The cub will be taken care of by the adult and the flock on its back until it reaches the age of 7, when it reaches sexual maturity and independentizes. When it leaves, some Ghinghases from the parent's flock will always leave it and accompany the younger individual.


Eiraghases are high in the food chain of Gorb Olohya, due to their massive size which leads to a lack of predators, with the Kataro being the only known beings in the satellite capable of hunting them. As petrophagous animals, Eiraghases don't directly predate on other lifeforms, but their blindness and the lack of accuracy when spraying acid can cause them to accidentally dissolve and consume other animals. Ghinghases have a symbiotic relationship with the Eiraghases, making both species important to each other.

It is unknown what role did the Eiraghases serve for the Frento, as there are few traces left of their civilization. It is possible that they posed a threat to them during both the early stages of their developement and the advanced stages of their civilization, as the massive creature's acid can melt through rock and metal, destroying structures and causing the deaths of people, and the Ghinghase flocks that usually travel on their backs can see the civilians as an easy prey.


Eiraghases have been taxonomically classified as akriids belonging to the Bipodicae family. Morphology-wise, they don't seem to have any close relatives, as they're the only members of the taxon with only two limbs.

Their binominal name is Eiraghase caelicaput, with the genus word refering to the creature's name, and the eptihet meaning air head in Latin.

  • The Eiraghase's air sack was inspired by the head of the Xenomorphs from the movie series Alien.
