The Promotion Ceremony of the Unshadowed – stripping away all power from Devil, purifying the body, and then slowly returning that power...
At first glance, it seems to have little to do with the "Priest of Light" and the "Unshadowed".
However, recalling the Navy's reaction to being corrupted by the power of the "Priest of Light," Sig could understand it somewhat—perhaps calling them "Priest of the Sea" would be more appropriate?
This isn't the first time Sig has played the role of the "Sun Path." In the world of One Piece, the imagery of the "Sun Path" seems to correspond to the sea.
Now Sig completely convinced, or more accurately, it's not the "sea," but... the Seastone Factor!
In the Paths of the Divine, the "Unshadowed" normally symbolizes the restraint of darkness and corruption. This Promotion Ceremony should be a ritual that leans towards the "Unshadowed"—only the target of restraint is more inclined towards "Devil."
Sig naturally thought of using the power of the concentrated Seastone solution...
At the same time, what Sig wants to figure out now is exactly what "Seastone Factor" and "Devil Fruit" are!
If even Vegapunk couldn't figure it out, how could Sig possibly understand it?
Able!
Because Sig could ask questions directly—inquiry—which is also an important research method.
Sig re-entered the "prison" in his consciousness, where both the Prison Demon and the Thunder-Thunder Demon had submitted—the latter having been forced to submit after Sig advanced to Sequence 5 and gained partial authority over lightning.
In addition, six more luxurious single rooms were added to the prison, housing the six Devil that Sig had been "Grazing".
As soon as Sig's consciousness entered, a gigantic "Evil Dragon" pounced on him... The dragon's head, resembling a lizard and complete with fleshy horns, nuzzled against Sig, becoming affectionate. Upon closer inspection, one could see green spots on the Evil Dragon's body.
That's right, it's "Bananaman" who has already entered the consciousness prison.
When Sig was captured, he also drew Bananaman into his consciousness, which is why he wasn't taken away.
Furthermore, in his consciousness, Bananaman's size is even more exaggerated— Bananaman's nature is quite special; it is a fusion of the consciousness of two Devil Fruits, possessing the consciousness of a common-type Spotted Salamander and Mythical Zoan Vampire.
The consciousness entity resembles Spotted Salamander, but with the added wings of a Vampire...
Sig summoned the Prison Demon and the Thunder-Thunder Demon, and they also came to the "luxury private room".
Of the six individual rooms, there are five Paramecia Devil Fruits and one Zoan Devil Fruit Devil Fruit. The Logia Devil Fruit, "Grazing," is somewhat useless because after "Grazing," it doesn't inherently possess the corresponding Devil Fruit ability; rather, it's more like being able to control the Devil Fruit within it, thus preventing it from Elementalization.
Moreover, the Paramecia are full of bizarre and powerful abilities, which are what Sig considers more valuable.
The only Zoan Devil Fruit Devil Fruit user is Catherine Demi, whom Zou fought in Sig before—this brutal female pirate who was also captured by the Navy and imprisoned on Level 6.
Sig discovers through Dream Infiltration that Katrin Demi was indeed acting under the orders of Repikak, but Repikak had already been killed by Sig on Enies Lobby, and Katrin Demi didn't know any more information about CP0.
When leaving Impel Down, Sig also took this "most vicious female Prisoner" with him, letting her Nine-Tails Fruit Grazing. This is the only Zoan Devil Fruit Sig is currently Grazing.
As for the Raccoon Dog Fruit, since it is still in its fruit form and Sig has high hopes for it, planning to personally fuse the Devil within it after Sequence 4 to ensure its power is maximized, it has not been "Grazing".
The Thunder-Thunder Demon still looked exhausted, and it was unclear whether this side of him was the will of the Fruit Devil, or... it was definitely the will of the Devil!
"The main reason I've gathered everyone here is to ask... what exactly is going on with you? How were you born? Why can the Seastone Factor restrain you? This is very important now, and I hope we can have an open and honest discussion..." Sig asked directly.
When Sig asked about it before, since only the Prison Demon had "Awakening"—meaning he had only reluctantly acknowledged and accepted Sig —he was reluctant to talk about it, and Sig didn't press him further.
However, with so many Devil Fruits present, after a moment of silence, the Prison Demon spoke up—the Prisoner's Dilemma is not only effective for humans, but also affects any intelligent being with logic.
"Marduk, Enlil, Tiamat... that's what we used to be called. Until Enlil launched a shameful rebellion against Marduk, who was king..."
"Screw you... We Enlil are the foundation of the world, the root of everything. You Marduk are nothing but withered branches of the World Tree!"
The Prison Demon had barely begun to speak when he was interrupted by the Thunder-Thunder Demon.
However, the Thunder-Thunder Demon's move was clearly not very wise, because... he couldn't gain any advantage at all—there were six Paramecia Devil Fruit Devil present, the so-called "Marduk," while he was the only "Enlil"!
Soon, the cacophony of voices silenced the Thunder-Thunder Demon's cry.
In short...
Sig understood that the consciousness of these "fruit Devil" originated from another world.
Their form of existence is fundamentally different from that of the current Earthlings and Moon person. "Marduk" is like the embodiment of the World Law, while "Enlil" is the embodiment of Natural Phenomenon...
Ultimately, a great battle broke out between the two sides. The "Tiamat" who were with them were relatively honest people, but some were recruited by Marduk and some by Enlil, and were given special abilities. These special Tiamat were the later "Mythical Zoan".
Later, their worlds were destroyed in the struggle, but their consciousness persisted, coalescing into a special "seed" that wandered the universe until it crashed onto the moon of Earth more than a thousand years ago...
Although described as a "seed," it was actually the size of a relatively large meteorite, and its impact directly damaged the moon's atmosphere.
According to the Prison-Prison Fruit and the Rumble-Rumble Fruit, they first sensed the power of "Seastone Factor" in the moon's atmosphere—it seems that Seastone Factor is a major component of the moon's atmosphere.
Later, they formed a symbiotic relationship with some of the Moon person in the form of Devil Fruits, which is how "Devil Fruit ability" came to be among the Moon person.
However, due to the previous crash and impact, the moon's ecology was greatly affected. Initially, a portion of the Moon person went to Earth to search for more Seastone. Some of them were Devil Fruit ability, so the Devil users were also very involved and knew about this.
Before enough Seastone could be transported back to repair the atmosphere, the moon's environment had already deteriorated to the point of being uninhabitable. As a result, the Moon person began to migrate to Earth in large numbers, and the moon gradually became a wasteland.
These Devil Fruit users only have a general understanding of the specific history of the Moon person, because their form of existence is different from that of the Moon person and Earth People. When the Devil Fruit user dies and becomes a simple Devil Fruit user again, rather than a combination of two, their memories as a "Devil Fruit user" become blurred.
For them, the experience of mating with humans or other life forms is like a dream...
However, it is certain that these fruit Devil are indeed "outsiders," while the Seastone Factor is a native substance that has a repelling effect on "outsiders."
Furthermore, combining their statements with the information Sig had previously obtained in Bilca and his understanding of Tesoro's body, Sig was basically certain of one thing...
