Hey genuine question what is up with ur Source Dragon of Death?
And I don't mean "why are they like that" or something negative, I absolutely adore ur funky lizard who seems to want to bring about a grief and revenge filled armageddon if I'm looking at your art correctly
(which i might now be, i am aware my media literacy can be kinda pants)
As for the depictions with death, you got it right, the lore about it is to show the aftermath of humanity who anger death, bring disrespect on mortality and how people take it for granted especially after executing the first master for death, being maked as the missing and forgotten source dragon. the whole back story is on my artfight account.
The source dragon goes by many names, depictions, and identities. They used to be at peace with life above, humans worshiping them alongside the other source dragons, finding balance between life and death. The first Spinjitzu master approached death for a request to give a human the element of death. At first, the source dragon rejected the request, knowing that humans are simple-minded and they will grow envious ,and fearful of death being right by their side, putting the person holding it at risk. But the young women convince them that if she does receive the elements, the source dragon can guide her, death finally agrees, but tells her to receive the elements that she'll need to drink their blood. So she did, but the consequence is her turning into a draconic beast with the element at hand. Death finally took her in, but over the years, death has grown a bond with the human. Seeing something more with them, over time, the shift of life and death has completely fallen out of balance. favoring life more, men finding ways to make themselves immortal, but the elemental master of death always comes to stop them, so the people hold plans to take out the elemental master so they don't have to worry anymore. Soon, they lore her to the center of the town, trapped and executed her. The people cheered and rejoiced that death would be no more, but "they" did not. The sky blackened, everything became cold, rising up was the dragon itself, in deep anger they started to bring destruction, what seemed to be the end, cries for mercy were called but they did not answer. Only the source dragon of life took matter in their own hands and used their power and bring the human back to life to calm death, soon death took the reborn child and flew to another realm, using all their power to create a new land called the land of freaks, now they rest at the bottom of the red lake, so the legend goes that if a bloodborne ever dies by the hand of man once more the ark of seven heads from death will rise once more while death be by their side.
