Feared and dreaded by the native populations, attacks from Deucalian dragons became such feared events, they were likened to natural disasters. Over time, mythological legends began to develop around Deucalian dragons, most notably being Jörðineyðir, the World-Eater, and Ánlögun, the Formless One. With Deucalia eventually becoming a lifeless world without organic life, the Deucalian dragons were once believed to have fallen into extinction. However, due to the nature of their reproduction, Deucalian dragons have since appeared on Helska III. Contents Biology Breeding Strengths Weaknesses Diet Behavior & Temperament Communication History Intent Biology Officially designated as super-predators, Deucalian dragons were massive serpentine creatures, spending almost the entirety of their lives in the oceans. Although a reptilian species, they were largely aquatic in nature. Deucalian dragons grow exponentially throughout their lifetimes; growth occurs during moltings, where Deucalian dragons shed their scales and skin. Deucalian dragons can molt as often as twenty times within a year, becoming less and less frequent as they age. By the time Deucalian dragons were known to reach adulthood, they could reach gargantuan lengths of three-hundred meters in or more, could swim at roughly 120 kilometers per hour, and had a mass that allowed them to swallow moderately sized seaships whole, making them almost inescapable in the seas. Deucalian dragons could live for centuries at a time, but were relatively slow to mature; it took several years for a larva Deucalian dragon to reach adolescence, and from there, took decades for an adolescent Deucalian dragon to reach the the earliest stages of their adulthood. Most Deucalian dragons had to be nearly a century old to reach the sizes commonly attributed to them. The oldest known Deucalian dragons were believed to be between five-hundred and seven-hundred galactic standard years old, although if provided with needed space and nourishment, a Deucalian dragon could potentially live for much longer; on average, provided it survived into adulthood, the average Deucalian dragon lived for some three-to-four centuries. Breeding A mid-stage juvenile Deucalian dragonDeucalian dragons reproduced infrequently and through a very particular process. Female Deucalian dragons could attract potential mates through the releasing of patterned frequencies of ultrasonic resonances which signaled males. Males typically fought one another for the right to mate, and confrontations were often lethal, which also contributed to the lower overall population of the species. Female Deucalian dragons released their clutches in the form of microbes in adhesive-like gelatinous fluids. that eventually develop into larvae. These spores-like microbes are extremely durable and attach to almost any warm and tactile surface. The microbes will begin to incubate into larvae once entering into an environment that can support them, namely, other creatures. Larvae will infest the living specimen, after-which the specimen will get consumed from the inside-out, with one or more juvenile Deucalian dragons emerging from the husk. Deucalian dragons breed only once every six seasons, equating to roughly once every galactic standard year and a half. Because Deucalian dragons are hostile to one another from their infancy onward, clutches may produce anywhere from half a dozen to just one newborn every breeding season. Strengths Deucalian dragons have extraordinarily durable bodies, although they can still be felled by strong-enough magnitudes of blasterfire. Their bodies are resilient to extreme pressures, which enabled them to dwell in ocean depths, and their skin and scales could withstand extreme cold, which some Deucalians utilized for protective gear. Their bodies are sensitive to vibrations in the waters, but are also almost immune to blunt forces and their skeletal structure is also resistant to vibro-weaponry and heat. Some Deucalian clans likewise discovered a use for Deucalian dragon bones as heat sinks or to create structures or weapons from. Deucalian dragons were also able to release extremely powerful soundwaves through a screech-like roar. While this was their way of communication over long distances during their mating periods, or to warn away intruders from their territories, they also used the aspect of their biology as a weapon, creating a sonic impulse similar to a thunderclap. Through this function, Deucalian dragons could release sound waves at decibels so intense they acted as a physical force, shattering Humanoid eardrums and cracking transparisteel. Weaknesses Because of their adaptation to the frigid temperatures of the deep oceans, the flesh of the Deucalian dragons are susceptible to extreme heat. While they can resist blasterfire from mundane sources, such as conventional blasterfire and most military-grade infantry weaponry, sources that produce high-magnitude plasma discharges can penetrate the density of their scales, such as fire from starships or artillery-level platforms. As such, with the correct hardware, tactics and opportunity, Deucalian dragons can be relatively easy to slay with through technological means. Diet A Deucalian dragon attacking a fleet of seashipsAs apex-predators, Deucalian dragons were exclusively carnivorous. Most of what they fed on were fat-rich aquatic mammals or massive quantities of fish for protein. On Deucalia, Deucalian dragons habitually targeted settlements, which became worse and worse as the planet drifted from the system's sun and became more frigid. This forced the Deucalian dragons to surface more frequently to find food. Deucalian settlements that were built over massive scapes of ice became particularly vulnerable to attacks, as Deucalian dragons would shatter the ice to cause the settlement to sink into the oceans below, consuming the inhabitants with it. Other common targets were seaships that sailed too deep into the far oceans. Submersible vessels were especially common targets, with many Deucalians being forced to discontinue the technology due to the danger. Deucalian dragons were also cannibalistic, with some actively seeking out peers in order to feed when other food sources become more scarce. During the final centuries of Deucalia's ability to support life, there were increasingly recurring accounts of Deucalian dragons battling one another in brawls that would even shatter the frozen grounds and reach the surface. After the Deucalian dragons eventually migrated to Helska III, attacks on Deucalian settlements once again diminished as the temperate environment and heavy saturation of fauna meant that the Deucalian dragons once again had enough prey to keep their appearances near the ocean's' surface a rarity. Behavior & Temperament Deucalian dragons were famously aggressive, ill-tempered and hostile. Likely due to their adaption on Deucalia, Deucalian dragons had an almost over-developed survival instinct; they constantly hunted, even when not in need or pursuit of food. Conversely, however, Deucalian dragons do possess a sub-sapient level of intelligence, particularly as they aged. Some Deucalian dragons were even said to have been able to set traps to draw or entrap seaships in the oceans to minimize their chances of escaping. Unless in the process of mating, Deucalian dragons were very-much solitary creatures, with encounters between them at most stages of their life resulting in territorial confrontations. Outside of the mating seasons, Deucalian dragons would consider one another either territorial threats or food sources, with the creatures having little-to-no social interactions with each other. In spite of their intelligence, the volatile and ferocious nature of Deucalian dragons makes taming or training them virtually impossible. Communication Because Deucalian dragons naturally dwell in the deepest parts of the oceans unless otherwise drawn to the surface, either by scarcity of food sources or becoming attracted to prey in distant waters. Deucalian dragons have internal organs that can generate massive magnitudes of vibrations from their throats, which they use to create ultrasonic impulses through the waters. These ultrasonic impulses can be remarkably intricate, with some resonances effectively acting as warnings to keep away from a Deucalian dragon’s territory, whereas other resonances act as various sorts of mating calls. History Deucalian dragons originated on Deucalia, prior to the planet’s descent into its lifeless state. Although highly adapted to survive in the increasingly harsh and frozen state of the planet, much to the dismay of the local Deucalian clans, they nonetheless were entirely wiped out as the world of Deucalia lost the capacity to support organic life. The species managed to survive extinction, however, with Deucalian immigrants that occupied Helska III with stocked food supplies that were infested with Deucalian dragon microbes at the time they were released into Helska III’s temperate wilds. Since then, Helska III is the only known planet Deucalian dragons are known to inhabit. Intent An expansion on the creatures Deucalians were familiar with, but also to provide the foundation for mythological figures in Deucalian lore that are based upon the creatures themselves. Can't be used for anything practical; cannot be trained, cannot be tamed. If you try to meet one, it will eat you. DO NOT PET THE SNAKE.
