One Piece is currently in its Final Saga, and fans are incredibly excited as Oda revisits some of the most significant parts of this arc, especially knowing that it has been developing over the past two decades. Oda has carefully crafted the storyline, and finally, the author has introduced the territory of the Giants into his narrative.
Elbaf is the second arc in the final saga, and the significance is that Elbaf will guide Luffy towards a new step to acquire the treasure of the One Piece. Although all these elements have been hinted at, this arc serves a much larger purpose and will undoubtedly pave the way for something even greater.

What the Giant Pirates Want from Elbaf
The Giant Pirates have arrived in Elbaf right after the events of the Egghead arc concluded. Since Elbaf is the homeland of the Giants, and they have a long-standing history there, their arrival makes perfect sense in relation to the Straw Hat Pirates.
When the Giant Pirates finally reached Elbaf, many covert operations have been hinted at by Oda throughout the initial chapters. Furthermore, fans are incredibly excited about all the lore related to the Sun God Nika. Additionally, several characters have been introduced, including Loki and two members of the Giant Warrior Pirates.

For the Giant Pirates, Elbaf is a crucial journey leading closer to One Piece in a way that is truly significant. Currently, they are searching for the last Road Poneglyph, and undoubtedly, whoever reaches this island may have information about the ancient weapons. This will become apparent at some point in time. However, it is clear that Elbaf is not merely the arc where Luffy will discover the last Road Poneglyph. Therefore, for Luffy and the Giant Pirates, Elbaf should fulfill another crucial purpose.
The only other significant purpose that this arc might serve in the storyline involving the Giant Pirates is to strengthen their alliance. After all, Luffy still has many challenges ahead, and the members of the Straw Hat crew must be prepared as well. Understanding Nika and other ancient warriors, Luffy is sure to seek ways to empower himself even further, which excites the fans immensely.
Similarly, other members of the Giant Pirates will certainly become stronger, especially in preparation for the upcoming alliance with the ancient warriors. Moreover, the importance lies in the Giants’ role in the next phase of the storyline.
However, Elbaf has much more to offer the Giant Pirates, particularly the support from the ancient warriors. Elbaf is a vast nation and will undoubtedly serve as a major military power. To this day, it remains the most powerful nation in the One Piece world. Whatever happens in this arc, fans are sure to see it lead to an alliance formed between Luffy and the ancient warriors, particularly due to Loki’s leadership.
What Does the World Government Want from Elbaf?

Regarding the World Government, they are certainly key players in the Elbaf arc. Recently, the World Government has sent two members of the Gorosei to the territory of the Giants. Both of them are incredibly powerful and represent the might of the World Government. The goal of their visit is to persuade Loki to join their ranks. The World Government could potentially force anyone to become part of the Celestial Dragons by granting them special privileges.
This is how York was granted the title of Celestial Dragon, and how Loki might also receive this power. If Loki joins their ranks, the Giant Warrior Pirates might become even stronger than any of the Emperors ever seen in One Piece.
At the same time, it is important to note that the World Government has other objectives alongside the territory of the Giants. The reason for sending the Giant Warrior Pirates to Elbaf is not only to persuade Loki but also to ensure the support of Elbaf and transform this location into a stronghold for them, even if they have to use force if necessary.
This is quite logical, as Elbaf has the strongest military in the world, and if they allied with any of the Emperors, the result would undoubtedly be a significant blow to the World Government. The World Government also desires the Giants to remain independent, and the act of conquering this territory would certainly bring about significant consequences for them.
By the end of the arc, the support of Elbaf will determine which side will gain the most advantages in the imminent great war, and this is precisely what makes this arc particularly unique.
