Osiris, this god had once descended from the Immortal Realm in a disobedient state.
The one who summoned him back then was Marquis Voban, one of the current earthly Demon Kings.
The Authority he usurped from Osiris was called [Cage of the Servants of Death].
[Cage of the Servants of Death]
Description: Grants the ability to preserve humans, divine beasts, monsters, artificial beings with souls, etc., personally killed by the user, as living corpses (living dead), turning them into absolutely obedient and loyal servants.
These servants, whose souls are imprisoned by Authority, can regenerate after a period even if their physical bodies are destroyed.
In addition, aside from divine beasts whose souls are too vast to move instantly, other Servants of Death will instantly appear at the Marquis's side from anywhere in the world with a single thought.
From Rin's perspective, this Authority was very convenient.
If he could bring it back to the Cardinal World, Rin could completely hand it over to Diablo and the others to raise a massive army of undead.
"If I can get a similar Authority, it seems pretty good too."
Rin craved the root power of the Egyptian mythology system, but he was also highly interested in all kinds of peculiar Authorities.
So, he planned to summon two Heretic Gods.
One was Osiris, the God of the Underworld and Harvest, from whom he wanted to obtain the Authority to establish the Netherworld.
The other needed to be a main god with significant status in Egyptian mythology.
Then, through him, he would plunder the Egyptian pantheon.
"Violet,"
Rin asked, "Do you have a way to raise the upper limit of this Authority based on the Cage of the Servants of Death?"
"Theoretically, there's no problem."
Violet replied, "As long as enough Ultimate Skill is injected into it, even the most ordinary skill can be stacked to an over-spec level."
In other words, while the Servants of Death's limit in the Campione World was divine beasts, in Rin's hands, it could become a true Cage of the Dead.
After all, the essence of this skill was soul binding and physical regeneration.
Similar abilities weren't uncommon in the Cardinal World.
Compared to Rimuru's devouring to grow stronger, or Velzard's downgraded absorption method, soul-binding abilities weren't particularly brilliant.
"I already have the Reincarnation of the Lord of Hope, and with Luminous's control over life and death as the King of Lust..."
If he had a good template as a foundation, Rin was confident he could construct a real afterlife in the Cardinal World.
While the Hell Road was also good, Greek mythology wasn't suitable for the concept of reincarnation.
In Greek myth, the concept of the afterlife and rebirth was rarely emphasized.
What existed was more like a resting place, akin to Valhalla.
"However, the Hell Road can still be used as reference. I'll integrate it later."
This way, Rin would no longer need to worry about the lifespans of the citizens of the Monster Nation.
Death would be just the beginning.
They could be promoted to heroic spirits like Valkyries, become long-lived races like elves, or have their souls live eternally, and even reincarnate within the Monster Nation.
Anyway, whatever other mythologies had, Rin wanted to have.
What they didn't have, Rin also wanted to create!
"The power of the Egyptian pantheon will satisfy you, Rin."
According to Violet's deductions, Egyptian mythology was perhaps the pantheon that explored the afterlife and the world of the dead most thoroughly.
At the same time, after forming a Divine Covenant with Rin, Set finally emerged from the Netherworld.
The so-called Divine Covenant was a special means similar to an alliance.
Its key feature was that divinity served as the medium, and once either party violated the covenant, they would be punished.
The consequences ranged from severe injury to divinity shattering and demotion.
Of course, this kind of alliance had little effect on Campiones.
But between gods, it was a binding force.
Set's request to never be troubled again was merely symbolic—it couldn't actually restrict Rin.
Fortunately, Set's demands weren't high.
As long as the covenant could restrict Rin for a few days, Set would be satisfied.
As for what happened afterward...
Set didn't really care.
A few days were enough to move his Divine Country out of the Netherworld and never see these walking calamities again.
"Beast of God-Slaying, are you sure you want to challenge my brethren?"
Set had mostly figured out the relationship between Rin and the black and white figures.
"They're your Subordinate Gods, aren't they?"
"Campiones must engage in fair combat to obtain new Authority."
Although, in the original work, few Campiones died at the hands of Heretic Gods,
That was only what the anime portrayed.
In reality, every time a Campione challenged a Heretic God, the risk was significant.
"This has nothing to do with you, Set."
Rin ignored him. "Don't worry. I won't break my oath."
Since the other party had helped, Rin didn't mind sparing him.
Afterward, under Set's guidance, Rin directly bypassed the usual requirements of priestesses and believers.
Instead, he used Osiris's "little brother" as the medium to complete the Heretic God summoning ritual.
"Who is it?"
"Who dares to desecrate my sacred relic?!"
A furious roar echoed from beneath the earth, and the entire desert trembled in response.
The gate of the Underworld slowly opened, and a cold wind seeped through the crack, stirring dust into the air, where it spun like phantoms dancing in the night.
Osiris, the King of the Underworld, appeared clad in a black robe. He looked to be around forty or fifty years old, with a beard, wearing a crown, and holding a crook and flail, as well as a scepter symbolizing supreme power.
He stood on a staircase built from countless steles. At a glance, each stele was engraved with the name of a judge of the underworld.
"Osiris..."
Seeing his old enemy again, Set couldn't help but murmur.
"Set!"
Osiris lowered his head and spotted Set, then noticed the canopic jar in his hands.
That jar contained the sacred relic of Osiris, sealed away by Set—his male symbol.
"Return it to me!!"
The freshly descended Osiris had yet to adapt to his new state.
He furiously raised the Ankh in his hand, a symbol that in Yu-Gi-Oh! meant Monster Reborn.
In an instant, a boundless darkness engulfed the oasis where Rin and Set stood...
