Oda Reveals the Timeline of the Three Worlds in One Piece

Chapter 1138 of One Piece is indeed a significant turning point in the story in many ways. It not only introduces fans to the strength of Figarland Shamrock but also touches on the most significant myth throughout the entire narrative, namely the existence of the Harley prophecies.
In the library, when Robin reads Harley, fans have seen Franky discover the Adam tree, where he intends to encounter a cultural heritage, being a record of the Harley prophecies from about 800-900 years prior.
This reveals the First World, the Second World, and the Third World, and encompasses the entire timeline of the One Piece world on a single, unique page. Below are the details of the Harley prophecies:
First World
The flames of humanity illuminate the earth, the human who desires to escape himself touches the Sun that has been scorched. Yet the unseen deity, and the God of the Sun appears. The God of the Earth remains hidden, alongside the flames of humanity that are being extinguished, enveloping the world in death and darkness. The chances of meeting again will never occur.
Second World

The hidden deity must reveal the secrets. The Sun does nothing but spread the flames of war. The people of the dying lands have seen a moment of peace. The human slayer of the Sun becomes the God, and the God of the Sea remains hidden. The chances of meeting again will never occur.
Third World
In the dark, there is almost nothing. The shadows wish to return to the day that has faded, and hear the voice of the moon that still resides. The God of the Sun dances and sings, leading the world to its end. The Sun shall return once more, and a bright dawn will arrive. Surely, this time, the chances will meet again.
Harley Confirms the Strongest Character in One Piece So Far

Harley brings to light several significant characters in One Piece, and undoubtedly the most important among them is the God of the Sun, Nika.
The God of the Sun, Nika, was first created according to the wishes of the ancient beings long before this in the First World. At the moment of his birth, he was immensely powerful as mankind had discovered an unlimited energy source. However, these ancient beings had to exploit the essential materials for this energy, which is why they prayed for their own existence to come from the cycle of life, which explains why the God of the Sun, Nika, came into being. Shortly after, the One Piece world was destroyed, possibly due to the overwhelming power of the ancient beings being created for the first time at this time. Nika died, and the First World ended.
In the Second World, fans have seen the hidden deity revealed in the Third World once again. This time, there is a strong possibility that a tree has been born and led to the creation of the evil fruit. Everyone has consumed this type of fruit and gained immense power. Meanwhile, the source of energy is referred to as the Mother Flame, which either exists or has once been created in this time frame. It spreads the flames of war, and in the end, the people of the dying lands and the Full Moon have prayed for Nika to appear once again; this is why the Hito Hito no Mi, Model: Nika was created.
This is precisely the moment Joy Boy appears in the story and the evil fruit’s powerful curse. Ultimately, Joy Boy awakened this evil fruit, leading to him becoming the God of the Sun, Nika. Unfortunately, the God of the Sun was captured by Imu, which is the reason why the Sea God, Poseidon, remained hidden for the first time, along with the use of ancient beings being submerged 200 meters. This is how the Second World came to an end.
However, furthermore, this world confirms the existence of the human who has long sought to find a way; a great war took place between Joy Boy and Imu, and Imu is the one who captured Joy Boy. The moment Joy Boy died, the Third World ended. Poseidon then remained hidden, as they could no longer meet again.
This is why Luffy’s return to the past as Nika is exceptionally significant. Because this time, he and the other kings, Poseidon, will certainly meet again, and a grand battle will occur against Imu, where Luffy and his comrades must triumph.
