In the past there had only existed 3 worlds, Heaven, Earth, and the Underworld also known as the Shinigami world. Heaven was a divine dimension, where the ancient race of humans known as gods resided alongside angels and other heavenly creatures. Earth was the residence of the gods creations man, beast and the other things that could have its creation traced back. Many of the earthly creatures had gained enough power to stand face to face with their creators which made the earthly universe divide into the mortal and immortal realms. The underworld was the land of death, the place where souls went to be reborn or they could reincarnate once they had perished. Those that chose to be reborn here were reborn as shinigami. Some feeling more native to this world than any they may have ever known as their memories of past incarnations return when becoming a shinigami.
In the Shinigami worlds capital one could see cities built into mountains as buildings seemed to go endlessly into the sky, while others hung from the rooves of massive mountain caves like stalactites. The city entrance at the base of the massive mountain could only be described as walking into a new world as a frog.
It was in this city that the Council of Death Gods resided. They each had their own deep cave abode within the massive city. In one of these caves 2 council members were meeting with one another.
"I know it's a taboo for a shinigami to create life but from my research only a shinigami about to breakthrough can create life without dying." the first Council member said with a serious expression.
"Wait, wait did you just bring up that taboo, you know that shouldn't be mentioned Wo Shie? What are you even talking about, we're supposed to be discussing our findings for trying to breakthrough beyond the Eternal Realm it's been a trillion years since my last breakthrough and three hundred-thirty seven billion years for you I know you've been researching since even before you became an Eternal." The second shinigami was a little spooked hearing what Wo Shie had just brought up but she cut him off because she wanted him to get to the point so nobody hears them discussing the taboo.
They were in a fairly secluded place within Wo Shie's deep cave that could easily fit a small town or village, ever since they broke through to the eternal realm they had a nagging feeling something was up with the shinigami world how every shinigami once becoming an eternal was recruited into the Eternal Darkness sect which was the top organization within the shinigami world.
Wo Shie was a fairly renowned shinigami, his mansion was on a 20,000 sq km plot located in the center of the cave with a straight path that led through a forest biome into a beautiful garden with fruit trees, vegetable vines and flowers with two glistening streams of water effortlessly flowing down the sides of the walkway leading to his residence. His mansion was a 4 story tall square building with gargoyles at all 4 corners on the roof and statues of dragons on each side of the tall arched double door that seemed to bea great deal higher than 2 stories high in the center of his colorful garden.
"Listen careful Marime.." Wo Shie started before being cut off.
"That's Lord LuĂ Marime to you you old fart now hurry it up! You know those old coots of the sect would bleed from their ears if they heard you talking about this!" Lui Marime interjected pridefully not liking how lightly Wo Shie was taking this.
Wo Shie had a sly smile on his face when he said, "Okay okay, 'Lord Lui Marime' hehe so what I was saying is any shinigami except a peak eternal shinigami would die attempting to Create life. Do you know why that is?"
"No why! Hurry up I don't like even talking about this!" Lui Marime was hurriedly trying to get off of this topic, she didn't know how the elders would respond if they came to know what they were discussing.
"We'll what I found is the first shinigami created life by creating the shinigami world and all of us are a result of his creation, it's said that when he created this world and us he disappeared, but he was only at the peak of the eternal realm which he recorded himself in an ancient ruin, in that ruin I also found a tablet describing how he was planning to breakthrough beyond the eternal realm." Wo Shie started to explain to Lui Marime
"You found what!?" Lui Marime was too shocked to hear what Wo Shie was saying, her jaw nearly hit her chest with her eyes wide.
"This is your second time asking me to repeat myself I'm starting to question your hearing, I found the ruin of the first shinigami inside there I found a journal of his describing the process to breakthrough beyond Eternal, it described a process of two eternal beings one being a shinigami that must breakthrough using the power of death and destruction and the other shinigami or eternal being use the power of life and creation…" Wo Shie explained his discoveries that left Lui Marime at a total loss for words.
Within the three worlds there was a tacit understanding of the checks and balances that existed. Due to this they would more often than not always to make sure to show one another their due respect as to not throw the universe into chaos.
The Eternal darkness sect and many of the other forces within the Shinigami world including the council of Death Gods were in charge of ensuring the constant and unencumbered cycle of life and death. Every now and then some living things manage to evade their death and from that moment it is the shinigami's job to apprehend and investigate them. Some of those individuals may have been blessed by fate or may be entities that have somehow evaded detection so it is the Shinigami of the underworlds job to investigate these cases and either guide the paths of those beings from behind the scene or to intervene and take the divined course of action sometimes teaching and guiding them overtly, recruiting them, or erasing their existence. But at no point was a Shinigami permitted to dable in the arts of life and creation as it would upset the balance of the three worlds.
Seeing Lui Marime's hesitation and doubts Wo Shie then continued, "That is not all I count there is in fact another way to breakthrough, if a shinigami is to cultivate the powers of life and death inside himself when he's at the peak of the eternal realm he can attempt a breakthrough but this method is more dangerous than having a partner, furthermore I also came across a method for a shinigami to cultivate the powers of life and I've already comprehended it. I would have attempted alone but knowing we've been friends ever since we could remember and I owe you one I figured we could both try to ascend."
Silence…
After about 10 minutes of silence Lui Marime finally huffed, " *sigh* I see you're already too deep in to be saved and now that I know I will also be implicated… so we may as well attempt our break through when do you think you will be ready for us to attempt our breakthrough?"
"Give me one months time I already have some attendants searching for an empty planet where we can attempt our breakthrough they have to look at 3 more empty planets the one's they've already seen would be destroyed if we broke through there so these are the larger candidates."
"I'll let you know when they find the planet and where we'll finally ascend. Once we decide the planet 3 days later we will meet there and attempt our break through." Wo Shie let her know his plan and they both went their separate ways to prepare their breakthrough.
When Lui Marime left Wo Shie began to recount the things he found in the Shinigami ancestor's ruins. He had received a lot, he began to go over the technique to cultivate the life energy, he wanted to be perfect before attempting the breakthrough knowing it was something that his body wasn't born to do.
