The Elbaf arc of One Piece has just dropped a major bombshell in the form of Harley texts and murals depicting the Adam treasure tree, leaving fans buzzing everywhere with connections to the powerful figures and the hidden secrets within.
Although the murals are described as being due to the influence of the childhood of the characters, they are quite detailed. Below are all the significant elements depicted in the murals that fans have been able to uncover.
Other Celestial Bodies in One Piece

One of the first and most intriguing celestial bodies in the mural is the moon, depicted right amidst the texts containing references to the first and second world government. Upon closer inspection, fans can see alongside the moon, the mural also illustrates various celestial beings, hinting at the Ohara incident, detailing the shape of the celestial bodies surrounding the blue planet in One Piece and suggesting a deep connection with the moon. This detail has sparked extensive discussions among fans for many years.
The Civilization on the Moon

Another notable celestial body depicted in the mural is the moon, which, although quite recognizable, holds some intriguing details worth examining. The depiction of the moon in the Elbaf mural includes circular formations that could represent volcanic mountains, but may also signify a civilization on the moon that Enel discovered.
The Skypeians are said to have migrated to the blue planet from the moon a long time before the world government era. Thus, these circular symbols may represent the process of lunar colonization and the establishment of the advanced civilization depicted in the world government era.
The Celestial Dragons Ascending the Red Line

Similar to the depiction of the world government in the second era, the mural also portrays a certain character with a glowing aura rising above the Red Line. This figure might be ascending the Red Line, as the body of the dragon seems to extend to form a part of the underground structure.
The glowing figure has long been identified as a celestial dragon in One Piece lore. However, it could also represent beings with a glowing aura, reminiscent of the noble families that have perished during the advanced civilization that is illustrated in the mural.
Slaves Working in the World Government Era

It is unclear whether the advanced civilization depicted to the right of the mural is the Kingdom of God or the next civilization. However, the mural has a tendency to suggest a strong connection between this civilization and Mariejois. The Elbaf mural depicts two slaves working under the ground, resembling a ship, reminiscent of a vessel mentioned in chapter 906, wherein a ship traveling to Mariejois is also depicted with slaves under the deck.
The Ancient Weapon Uranus

One of the more fascinating celestial bodies depicted in the Elbaf mural is a flying vessel that closely resembles Enel’s Maxim. This vessel may be modeled after Uranus, given the attack on Lulusia from above, it is undoubtedly a type of flying ship. The ship in the mural also appears to be attacking with a beam of lightning, akin to Lulusia being assaulted by beams of light from above.
The Noah

To the right of Franky and the Adam tree, there is a ship that resembles the Noah, “the ship of the legendary people,” currently docked at God Valley. There are two people and a pair of beastly creatures, mimicking the story of the Noah ship in the scriptures that One Piece clearly draws inspiration from in this instance. It even suggests that the narrative might not be the final tale in the scriptures that could appear in the mural.
A Skypeian

One of the more challenging elements to decipher in the mural is this Skypeian character appearing beneath the waters next to Noah. This may be a representation of the plight during the world government era where Skypeians had to migrate to the land of the Gods, although it currently remains very difficult to pinpoint any specific context.
Imu the King of the Void

Another intriguing detail in the mural is a character resembling a ruling figure, which fans speculate could be Imu from the World Government era. This ruling figure appears to be on a ship while Noah and others remain below. Meanwhile, the ship resembles Uranus in the sky, sinking beside the ruling character, causing the ocean to rise higher, reminiscent of events that transpired with Lulusia.
The Eve of the Sun Tree

Although not a significant celestial body, the tree in the center of the mural holds more importance than fans realize, with speculations suggesting that it could be the Sun Tree Eve. It was first mentioned in the God Valley arc, and its location on land has yet to be clarified. If the events depicted in the second world government arc are to be revealed, then the Sun Tree Eve could potentially relate closely to the origin of the ancient weapon created by the God of the Sun.
Interestingly, the initial concepts of Romance Dawn included a mythical tree that Luffy’s ancient weapon is said to originate from. Although Oda has hinted at these ideas since their inception, the connections seem to lean too heavily toward the concept of the ancient weapon as Shanks recently referenced Shamrock.
A Mink

On the tree, there is a creature with a long white fur coat and a long tail that resembles a Mink in its Sulong form. The Sulong form is subtly hinted at by the white color of the fur on the mural. This suggests that the Mink tribe has historically aligned themselves with Joyboy or Nika in ancient times and may potentially do so again in the future.
Laboon/A Whale

Beside the Mink creature is a whale reminiscent of Laboon, referring back to chapter 968 of One Piece, where Roger and Oden hear about the whales talking about the incoming danger posed by Shirahoshi or Poseidon, hinting that she is one of the two kings destined to protect humanity. It remains unclear who that king is or why “king” is being employed, even though the depiction of a whale in the mural subtly suggests that these whales, including Laboon, may also align with Luffy or Nika as events unfold.
A Lunarian/Seraphim

Next to the whale, the mural also portrays a Lunarian character with dark wings and flames behind them. This could hint at King or Alber connected to Luffy in the future, or the depiction might even represent a Seraphim, suggesting a potential internal conflict with the World Government. Such a character could align perfectly with the conclusion of One Piece.
Luffy with Nika’s Original Shield

The most recognizable character in the entire mural is Luffy or Nika the Sun God. The illustration appears on the left side of the mural, suggesting that this could be a representation of the world government era and events in the future. One can see an image resembling Nika reaching out with a hand similar to Luffy’s Gear 5 state, along with a shield that resembles Nika’s depiction in Elbaf. The shield features symbols that have historically appeared on the Kozuki family crest and has been speculated by fans to represent the Kingdom of God or even the Jolly Roger of Joyboy.
