Crypt Dragon's 101
The following documents are an overview over the biology, history, and culture of the kaiju that are known today as Fatalisdraco abyssus. Commonly known around the world as "Crypt Dragons". Sometimes referred to as Tomb Dragons or Tomb Wyrms. All below is based on human theory, and what the monsters Phenoraixa and Grimm have both told.
As well some artist comments.
Chapter One: What is a Crypt Dragon?
Crypt Dragons are in all terms of the word, a dragon. They are reptilian, breath fire, fly, and to an extent, are fascinated with items of value such as gold, silver, diamonds and other various gem stones. As for what kind of reptile, there are a handful of theories to there classification, but only one that stands out among the rest. To date, only one order of animals that the dragons resemble more then any other: The Squamta. The same group that includes all forms of lizard and snake.
However there is more to there ancestry then just lizards and snakes. Recent studies show that a Crypt Dragon has Quadrate Bones resembling that of other Squamata members, though not quite as flexible as many of there cousins. Comparing the skull structure to many modern day relatives, the Crypt Dragon's skull shape shares few similarities to confirm it.
It was discovered that experts were looking in the wrong place. There was a third member of the Squamata group that was overlooked at first: the Mosasaurs.
Mosasaurs were a group of Marine Reptiles living during the dinosaur age. Putting them side by side, the skulls had many similarities from the teeth to even the shape; minus the horns and curve the muzzle ever so slightly. This discovery has lead to the idea that somewhere along the line when Mosaurs were evolving along there rapid path of evolution of only six million years adaptations to the waterways, that the early and primitive ancestors of the Crypt Dragon had appeared.
Some time later near the end of the Mesozoic Era, Crypt Dragons had been fully realized and had become not only a dominate and prominent species, but an evasive one as well that threatened the planets very balance. Or so the theory goes.
When the KT event happened and ended the reign of dinosaurs, the dragons, being as large as they are, seemingly vanished as well from the earths history. With the planet already under stress for various reasons, the meteor brought and end to the planets first reigning species: both of them.
Naturally they didn't die out, nor was it the last time the dragons would be seen by the earths history since both Crypt Dragons, Hera and Thanatos, both are alive in the present.
Chapter Two: The Second Rise
For millions of years, the dragons had not died, but had went into a sort of hibernation that could rival that of a Water Bear. Most of the species did indeed die out with the terrible lizards, but some still lived. They waited, and slept, until the day came when the earth was able to sustain there species once more. Only a few thousand years before the rise of man, Crypt Dragons had returned. Ever since man could tell history from paintings on his wall, dragons have been seen by human ancestors. This means at the very least, they had reawakened before humanity, giving a sturdy idea of when they returned.
The other reason this theory is widely accepted by the present is because there was no more major extinctions up until man kind first arrived.
Not only had the dragons arrived, a second organism had also appeared on earth that filled a very similar roll as the dragons: The Garuda's. Garuda's first appeared in the east, though to be around what is now India and Asia, where its believed the dragons appeared what is now the Americas. It wasn't until both species rose to power and into cultures when there blood feud had began.
Chapter Three: Culture Appears
Millions years have past since they had returned, and the dragons began to flourish. Not only had they once more claimed many continents, but many have split off from there original ancestors and started there own population. Not onto did they split off, over time they had grown farther more intelligent.
It got to the point were the populations had become tribes and began warring on each other. Many bloody fights came and went. Hundreds of years of fighting, and eventually it came down to a handful of populations, each controlling a continent; North America and Canada, Central America, South America, Europe, Greenland, Africa, and Australia had all become the kingdom to each population of dragons.
As time went by, many what could be called Civil Wars broke out among there own which all led to different ways of living.
Cultures thrived, Each different. Some were more brutal and veracious than others. The culture of Aztecs, Mesopotamians, Incas and many others had sacrifices to the dragons as part of the dragons rule as an example.
Others such as Africa were more peaceful, at least by the standards of others. The worst by record according to one living Garuda, Phenoraixa, was Australia. Australia was once said to be mostly lush jungle like in the northern areas. According to the bird, the dragons there feel into anarchy and eventually burned there own world down until most of the continent had become barren and unsuitable to all but the truly adapted.
Eventually it came to the point were the continents were reached ruled by one lead male who ruled over all other female dragons within there domain. After that was decided amongst there own, there was much peace between each, what became species, of Crypt Dragon. The inbreeding became a issue of how "pure" each species had claimed itself to be. This of course became part of there downfall
Language of the dragons is completely lost. No records of it exist, and what little of the culture survives are un unreadable ruins that are found in South America.
Chapter 4: What of humans in this time of dragon rule?
Humans may have suffered the most in the time of the Crypt Dragon. Many species suffered from predation of the titanic creatures and ultimately extinction. Humans, on the other hand, were either smart enough, lucky enough, or maybe even unlucky enough to live alongside them. Some parts of the world worshipped them as gods, deities, devils and other supernatural figures of great mythology. Others suffered. Old tales of knights putting there lives on the line echo to this day and beckon a second glance from the world.
Some parts of the world during their reign, humans were ignored. Others were recognized, and others sought humans as a means of labor. South America is the greatest example of this. Gruesome sacrifice and heavy payments in order to survive total genocide at the wrath of an angry dragon. Tributes of gold, temples and worship led to a dark age that could only be described as similar to the Age of The Jaguar if it took a dreadful twist of even darker methods.
About the time near the golden age of the dragons, humans had actually discovered methods to hunt down Crypt Dragons successfully. Methods included massive nets large enough to entrap an adult(or a younger juvenile at least) and the use of truly gigantic weaponry of primitive designs. Later methods included the famous invention of gunpowder from the ever clever Chinese who invented it. Eventually the idea of fireworks lead to the first rockets, and the age of dragonslaying became well known. This also ended up as part reason for when the Crypt Dragons had became near extinct for the second time in earths history.
Chapter 5: Dragon Ecology
Thankfully there's much evidence to the ecological life behind Crypt Dragons, other then there unusually interesting culture that surpass chimpanzees and rival human beings.
Due to there size, almost anything under the sun was considered prey to the them. However there main diet did not come from animals, but a species of mold of all things. Another kaiju and a very inactive one at that, Ambrosia Mushrooms make up over 50% of the diet for all Crypt Dragons. Not only that, but the two species can no thrive without each other.
Ambrosia require a very high temperature to germinate there spores. Only three place's on earth offers this: Volcanoes, there own means of producing flame, and the flames of Crypt Dragons which burn by thousands of degrees Fahrenheit. Spores of Ambrosia can always germinate in the volcano their parent exists, but there is only so much space. That is until the dragons came. The idea is that the spores will attach to the dragons and be transported to new volcanoes where spores can germinate into new colonies of Ambrosia, thus spreading the species.
In turn, the dragons get more of there food source, but that is not all. As it turns out, Crypt Dragons need to eat Ambrosia at a young age in order to breath fire. The bacteria that produce the napalm gas in there stomachs has to be gained and not there by birth. So it is crucial that both species survive to benefit each other and keep there own species in alive.
When it comes to breeding, Crypt Dragons are interesting in almost every way. Mating behavior changed through out the history, but the most notable is when one male reigned over an entire continent and all females within there reign were owned by the one single male. Other males did exist, but almost all were the son offspring of the dominant male and thus loyal to there father.
When a female enters her estrus, the lead male mate with her several times before releasing her back to her own nest. Once a female is carrying eggs, she will construct a nest of ash, rock, and water to make a sturdy foundation. After the nest is built, females will lay anywhere between one and eight eggs.
After that, its guard duty for the female. Dragon eggs take about five months to hatch. In the mean time, females never leave the nest unless chasing off threats. Crypt Dragons are also communal nesters, nesting around each other for greater protection if the opportunity arises. Crypt Dragon parents are so attached to there offspring, that losing them can send them to near madness. Some never recover.
At last when the eggs hatch, the offspring have a habit of getting into every sort of mischief possible. Every bit as vicious as there parents, they get into everything. Under there parents feet, in there fathers den occasionally, and having more then enough fun burning down human structures.
Lesser males become a sort of elite fighter for dragon populations. Where females are the typically seen members, males are bigger and more armored with a dark coloration that is similar to black volcanic slate. Full of testosterone and ambitious as all males would be, they itch for fighting and often do fight. If not fighting, then its torching something.
After a few years, young draclings are sub adults and find there place among there sisters, mothers and aunts. Most become just more of the ever growing harem where others either abandon there home range to seek a rouge life, or a life with another male that isn't there kin. Others are traded.
Chapter 6: Downfall of Crypt Dragons
Many factors contributed to Crypt Dragon decline to its two surviving members today. One issue that probably became inevitable from the way the culture of the dragons existed was inbreeding. With only a handful of males ruling large masses of land, it was inevitable. Immunity faded and genetic defaults saw to the survival of the fittest, so to speak.
Another factor was humans. Human beings had rose to power at one point with gunpowder, brains and other elements that lead to ways to killing Crypt Dragons of various sizes. To what extent is unknown, but if juveniles can be killed before they even grow to adults, then it came to no surprise that humans became part of the reason.
Another reason is the dragons own greed. Referring to Australia again, the dragons proved too successful to last forever. They had begun to burn themselves from existence out of there own nature.
However the biggest reason of all is the Garuda's. The collision of species, both were severely dented in population. Out of the two, Garuda's were the first to die off save for Phenoraixa, Grimm, and there mother. After there mother was killed, the two single handedly saw to the utter genocide of almost all of the species. Only two known dragons are alive. It is possible others could still be dormant.
Chapter 7: Crypt Dragons in Other Universes and related species
For a kaiju, Crypt Dragons are very adaptable and diverse to the point that there existence stretches beyond dimensional barriers.
Neith is a cousin species of the Crypt Dragons, called a Tomb Dragon. Instead of flame breath, she spits acid and is an unusually calm creature. As well, her species is herbivorous opposed to the carnivore diet of the original species.
Tezzera is yet another dragon that has adapted to such a severe environment that it is a near god. Tezzera and his kind are a species of Crypt Dragon that live in between dimensions. They are able to tear holes in dimensions, creating a pocket outside of time and space for there homes.
Another universe has so many species in it, that the dragons are proven to be possibly the most adaptive kaiju to exist.
