Garling ends Rocks and God Valley sinks

In One Piece Chapter 1166, Garling lands the final blow on Rocks. This news is shocking as no one expected him to be the one behind killing this legendary character. Moreover, we know that Rocks was already injured after sustaining some heavy attacks by Garp and Roger. Yet his end arrives through a cleaner, colder act: Garling taking the opportunity to kill him while he was already weakened.
The events that take place after Rock's death in One Piece Chapter 1166 are equally dramatic: God Valley Island sinks into the sea, thus completing Imu’s order from the previous chapter, where Imu ordered that this location be erased. Although we still do not know how that happened. The downfall of Xebec is shocking news, and it creates disturbance across nations, setting the stage for the balance of power for the future.
Rocks’ dream, Loki’s role, and Shanks’ discovery

One of the most interesting reveals in One Piece Chapter 1166 is when Rocks reveals his dream of Loki. He wanted to become the King of the World. This is a direct relation around Davy Jones and the idea of an ancient ruler predating the World Government in One Piece. Moreover, it is interesting to analyze this revelation, as it ultimately deepens the parallel between Rocks and Blackbeard.
Both of them ended up inheriting the ambition to stand at the very top of the world. The One Piece Chapter 1166 also gives us the long-teased moment many fans waited for: Roger finding baby Shanks inside a treasure chest. It’s a brief moment, but this marks the beginning of one of the most mysterious relationships in the series and reinforces how deeply Shanks’ origins are tied to the God Valley.
Dragon is imprisoned in One Piece Chapter 1166

Another major highlight in One Piece Chapter 1166 is Dragon being taken to prison because of his actions in this Incident. He showed insubordination and is now being punished for this. This kind of punishment is expected by the World Government because they have never shown leniency towards this kind of behaviour.
Then comes one of the most wholesome moments when Garp goes to visit his son. And during this meeting, for the first time, Garp does something that is against his code, and he breaks his son out of prison. This is the beginning of Dragon eventually becoming the world’s most wanted revolutionary, and it makes sense why Garp carries the burden of protecting both the Marines and the people he cares about.
Harald breaks his horns and begs for peace

This One Piece chapter ends with a heartbreaking scene where King Harlod breaks his horns as a gesture of grief after knowing about Rock's death. Overall, this chapter ended on a tragic note while setting the stage for the events of the future. In the end, Chapter 1166 delivers closure, shock, and setup all at once. This is exactly what a God Valley finale should feel like, and Oda delivered it like the master storyteller he is. And with no break next week, the story is about to accelerate even faster.
