[hider=Primarch X]
[i]Name[/i]: Dorath'en'Vorth - "The Dragon of Woe"

[i]Legion[/i]: Pyre Raptors, the Xth Legion.

[i]Homeworld[/i]: Phlogiston Quaternus - A world of dragons. Literally. There is no word for "animal" or "creature" on Phlogiston Quaternus; the concept of dragons has overtaken it wholly, and for good reason. Every single beast on the planet short of humans themselves takes the form of some sort of draconic entity, ochre-skinned monsters engulfed in purple chitinous armour, with bio-plasmic breath weapons galore. A great many of these even have wings - dragon-eagles, dragon-wolves, dragon-tigers, even dragon-turtles - and if they aren't dragons with wings, then they are likely their six-legged drake cousins, who in truth are simply lesser dragons. Furthermore, the flora of Phlogiston Quaternus is warped and alien in form, whilst the air is typically choked with spores spat into the air by these plants: wonderful for the dragons, inimical to humanity.

One may wonder how humanity has survived on this world; nay, thrived, for their hive cities are grand and technologically advanced, in spite of both the local environs and external factors. Not towering constructs of reinforced rockcrete and plasteel, these spires are smaller, far more stable, and even pleasant to the eye, though each is surrounded by autonomous defense systems keeping out dragon and drake alike, though the exact nature of these systems goes unknown to the typical civilian. More concerning to an outsider are the gladiatorial pits that most of these cities seem to use as entertainment, scattered across the levels and even extending into multi-storey amphitheaters for those from certain cities, wherein those ruling up above as well as the more typical citizenry further down enjoy gory spectacles on a daily basis.

The truth is, though most know it not, Phlogiston Quaternus is a low-level Daemon World, or at least headed in that direction: not yet dragged into the Warp, but inching ever closer with every deal the ruling sorcerers make with their "aether-dragon familiars", every life sacrificed to them for personal gain and protection of their territories, every soul burned by the pits to fuel their city's defense systems. Perhaps the only reason it has yet to fall outright is due to how these hives tend toward internecine conflict over which way of life is better - that is, which Chaos God ought to reign supreme upon the world - as well as both daemonic and mutated threats spawned from within and the draconic nightmare beyond their bounds, devouring everything within their walls when they tumble into outright madness long before the madness can spread beyond them.

Not all cities scattered across the world are so vile, but few remain that have not taken to this brand of disturbing symbiosis, and those that do are ever-imperiled by the creatures lurking at the walls of these easier, more resource-dependent targets. The Long Night has been long indeed, and the race to the bottom is swift when the price can be readily paid by someone else.

[i]Psyker Grade[/i]: Uncertain, no formal measurement. Likely Gamma, focused on Pyromancy and Telepathy with lesser presentation of Biomancy.

[i]Skills/Abilities[/i]:
[i]Draconic Figure[/i] - A mix of factors has led the Xth Primarch to develop a look akin to that of the mythical dragons of Ancient Terran lore. Whilst still recognisably human in frame, his pupils present as cross-shaped slits within flame-like irises, his fingers are tipped with diamond-hard rending claws, and he need only open his mouth wide to reveal a mawful of oversized, retractable teeth, with features representing a wide range of predatory beasts. In addition, he seems to be all but immune to heat and flame alike, not so much as charring in temperature ranges including those of molten metals, re-entry speeds, or plasma blasts and other heat-based weaponry. Lastly, whilst any of the native abilities of a Space Marine are naturally enhanced in their Primarchs, the Xth's unusual modifications lead to his upper gastro-intestinal tract and associated glands producing substances that mix into something closer to self-igniting promethium than acid, letting him more or less spit napalm at enemies and consume substances that even other Primarchs wouldn't risk stomaching.

[i]Survival[/i] - Dorath'en'Vorth is unnervingly capable of surviving in, quite literally, the most inhospitable conditions known to mankind. He possesses an inhuman tolerance for extreme conditions, from intense heat to glacial cold to radiation that would kill an Ork in minutes, as well as an innate understanding of what is and isn't useful for survival under such duress, including what can and cannot be consumed for sustenance. Furthermore, his body will continue adapting to these conditions over time through exposure, making them ever less concerning for him even as he instinctively processes how best to render an environment that most would consider unworkable suitable for human life and further occupation.
Should a locale prove utterly uninhabitable even to his extraordinary physique, or in other equally extreme circumstances, he can enter what is essentially a state of cryptobiosis: the suspended animation of lesser Space Marines extrapolated to the natural logical conclusion of a Primarch's near-demigod physique, complete with a nigh-indestructible cocoon of hardened bone, keratin, and chitin, as his physique gradually adapts to the outside environment until he is ready to emerge once more.

[i]Creature Empathy[/i] - To complement his innate survival traits, the Dragon of Woe has an unnerving capacity to telepathically commune with any local wildlife, even those that ought to be extraordinarily hostile. Through subtle psychic rewiring and what may as well be innate animal magnetism, he is able to convey his wishes to fauna expertly, and without further goading they will assuredly be followed through on. Indeed, this connection seems to remain even after he has left, letting him more or less domesticate creatures that would be basically unmanageable for anyone else, and ensure that they remain in that state even with planetary, and perhaps even astronomical distances between them.

[i]Infernal Rapture[/i] - Should worst come to worst, and Dorath'en'Vorth suffers from mortal harm, he has one final trick up his sleeve. Rather than merely succumbing to injury, his body will sooner or later ignite, spontaneously combusting from within and searing away those threats about his person, before the Dragon of Woe steps forth from the pyre in phoenix-like repose, unmarred by his past wounds. What this represents on the level of his soul, whether it be a potent psychic reaction or something more meaningful, remains to be seen.

[i]Appearance[/i]: As described above, Dorath'en'Vorth's features have a distinctly draconic bearing. However, his body is still far from unrecognisable as human. Indeed, behind the natural weapons, he is almost average in appearance, at least for somebody destined to become an 11'7" tall wall of lean muscle with limited interest in self-grooming; but at rest, he bears quite unremarkable dark-brown hair, tied together into wide, pointed locks for the sake of keeping its length out of his eyes, and his skin is a distinct tan blend averaging about every tone one might find within baseline humanity, with scarring to spare too. Of course, in more extreme environments that demand it, his skin tone is likely to shift drastically - but strangely, so too does his hair, seemingly changing colour with no shedding. His musculature and even skeletal height are prone to warp swiftly yet subtly too, in appropriate circumstances; regardless, he is not consciously aware of these changes as they happen, and rarely implements them with intent.

[i]Concept[/i]: Terraformer - The Xth Primarch was designed with extremely malleable DNA bases, essentially mixing together a great many Terran animals to provide, at least in due course, whatever biological tools he might need to survive even on the harshest of worlds, and from there to engage in whatever activities were necessary to convert that world into a planet suitable for habitation by humans.

[hider=Legion X]
[i]Legion Name[/i]: Pyre Raptors

[i]Associated Primarch[/i]: Dorath'en'Vorth

[i]Concept[/i]: Charging in on assault bikes, speeders, jetbikes, jump packs, and grav-vehicles, the Xth Legion is designed with the intent to break down enemy civilisations to the point that they can no longer resist invasion by the Emperor's greater forces. Their purpose in war is not merely to defeat their foes, but to end their threat by violently sabotaging their logistical infrastructure - ideally before they can even understand that everything they've strived for has been reduced to nothing more than ash and rubble - and then frustrating efforts to rebuild until either society collapses under the inertia of failing supply lines and non-functional core industries, or additional forces finish the job of crushing all resistance. Stealth is an option for the Legion if needs must, but it is a secondary tool compared to the preferred modus operandi: pushing to the heart of the enemy in a rapid, overwhelming spear of destruction, typically through the application of intense heat, with volkite, fused hydrogen, promethium, plasma, and phosphor providing the standard firepower for this Legion.
In turn, however, they inherit their Primarch's drive to follow up by restoring the sites they have devastated after surrender and occupation has been achieved, rendering them suitable once more for humans to start living and building in, as well as restructuring those worlds whose ecosystems may not otherwise be suitable. This post-war rebirth may be seen as a waste of good Space Marines by some, although with how quickly they can act in revitalisation after initial destruction, and the extended need for suppression of rebels in the short term, they are rarely an unnecessary placement until greater manpower can be implemented.
