Veldora Tempest is a Catastrophe Class being, who Guy considers a natural phenomenon rather than an individual.
“Probably no—if I had to answer, probably ‘True Dragons,’ but they are more like natural phenomena.” (Volume 11)
Great Spirits Gave birth to True Dragons, and True Dragons were born at the same time when the world is created. They are stated to be a Source Of the World ( Type 2 Concept: Dependent Concept, If it's destroyed it would destroy the world too ) because of this
Velgrynd smiled fearlessly, remaining unperturbed in the cage of hypergravity.
“As expected of a demon overlord. Your magic is perfectly powerful. However, for so long as you are bound by the laws of this world your attack won’t work against a True Dragon.”
As if to prove her point, Velgrynd shattered the jet-black pillar from within. She raised her mana and interfered with Carrera’s magic, rendering it powerless.
“Hahaha! As expected of Veldora-sama’s sister, you’re making it seem like a joke. If magic doesn’t work, then there’s nothing more I can do, huh? No! I have a sword technique I’m learning from Agera. It may be useless, but I’ll give it a try!”
Carrera seemed to be enjoying herself, even though her best move had just been defeated. Without any sign of distress, she raised the sword she had created with magic. The beautiful sword had a fierce presence that was unbecoming of a demon. Carrera’s magical energy flowed directly into the blade, giving it a radiant glow.
“This is most likely our only choice. It is not simple magic nor Skill, but a technique you have developed and improved yourself. It may work even against the True Dragons, the source of the world. Veldora-sama says that a woman named Hinata has proven this approach effective.”
Without needing to test it, Testarossa knew that magic would not work on Velgrynd. That was why she had materialized a whip using magic from the very start. The whip was white— a magic formula devised by Testarossa, possessing a contradictory nature known as “freezing white flame.
In this part, it explains that the True Dragons are ancestors for all dragons out there.
And As much as we know When True Dragons are born they only have their will so " Holy Will of Nature " is not just what people call them.
Sometime after Guy awaked to become a demon lord, it didn’t take long before someone else awaked to become a true demon lord.
That someone was Milim. The ancestors of the four “True Dragons” emerged to the physical world and bred with humans.
What incredible thing was that the “True Dragon” who reproduced with humans were deprived of most of its power by their offspring. From then on, the breeding of True Dragon and Human became a taboo.
The true dragon who lost its power exploded into pieces. But it was successful in obtaining flesh on the ground world. It became the ancestors of dragon race.
The future generation would instead call the “Holy Will of Nature” as the “True Dragon.”
Nowadays, the dragon race is able to prosper on this land and its origin can all be traced to this one ancestor dragon.
And as long as Their Will exist they will still Exist and they dont have any attachment their body. Their Material Body depends on their will which is ( Abstract Existince Type 2 : Information Type 2 )
They Dont have any attachment to their body
But Their Spiritual Body is their Will because
As the Great Sage explained, there were three types of topological forms in the world: astral bodies, the weakest form that surrounds the soul; spiritual bodies, which can form a base upon which to build one’s internal force; and material bodies, those directly connected with this world. The human body is the combination of all three forms.
A high-level elemental is nothing more than a mass of energy that gains sentience. In other words, it uses the “heart” protected by its astral body to control its spiritual one, you could say.
High Level Elemental is Littelry is using its [ Spiritual Body ]
They cant exit with only Astral Body or Soul , but it was stated that Spiritual Life Forms can Exist as long as their wills exist ( Including True Dragons )
Of course, some monsters really don’t need a brain—their intellectual makeup resides in their astral or spiritual bodies instead. There are even some supernatural creatures who think with their “hearts,” so to speak, instead of any brain organ. Think of it as kind of like people who’ve gained the Complete Memory skill, such as Shion. All that does is re-create memories, of course, but it opens up the potential for thinking purely with one’s soul and astral body… And once you achieve that, it pretty much releases you from a physical life span and punches your ticket to spiritual livelihood. Once that happens, pretty much no physical attack can deal fatal damage, and if your physical body’s torn apart, you can regenerate it at will. Only certain special attacks, or weapons graded Legend or higher, would be any kind of threat.
Adalmann hadn’t quite reached that point. Wight kings like him are spiritual monsters, yes, but he’s still bound by the yoke of his physical body. His thought processes are all contained within his spiritual body so there’s no such thing as dying of old age for him—but even so, he cannot continue existing with just his soul and astral body. He was this close to becoming a spiritual life-form, but he wasn’t quite immortal yet—that kind of thing.-Volume 14, Chapter 1
Spiritual Life Forms Can Exist with only their wills
Spiritual Body Contains Astral Body , Soul
Adalman is not a complete spiritual life form so he cant do that what spiritual life forms can.
Spiritual Body is (Abstract Existince Type 1: Concept Type 2 )
So Their Spiritual Body will fade away in Material World If they wont find a Material Body or Incarnate Themselves inside it like
[ Diablo ] , Or can Create a Material Body Like Veldora or Fade away like
[ Ultima ] but don't forget ultima didn't fade away instanly , nor her subordinates. Ultima Used her energy too much so she started fade away when she came to material world and in one of the spin-offs ( Yes, Trinity Tempes is Canon ) she didn't fade away instantlly either.
so its combat applicable.
This also applied to draconic races like Veldora, but in his case, he not only had a spiritual body, but he had a material one made from matter in the local area that he could freely control. High-level elementals didn’t have that kind of power, so when they left the spiritual world, their energy would disperse, and they would disappear. This is the fate that awaited any type of spirit-based life-form in the physical world, including angels and demons.
To keep their energy from fading away, they must either find a physical receptacle to form a pact with or a way to physically incarnate themselves. That, in essence, was what
made the material body so important in this world.-Volume 4, Chapter 7
Govern the principles of the world, Here It shows that The True Dragons have Attributes like Spirits.
A divine monster spirit was a subordinate existence of the ‘True Dragon’ race. Like the ‘True Dragons’, they had various attributes, and fire was considered to be a major attribute. Attributes were the laws that governed the principles of this world, and there were eight kinds in total. (Volume 14)
