The Emerald City is a legendary metropolis mentioned by Bellamy during his speech about dreams, alongside the City of Gold and the great treasure of One Piece. He dismissed them all as pure fantasy. That was a long time ago, right before the Skypiea arc.
The “emerald city” mentioned by Bellamy is possibly a reference to the Emerald City appearing in the famous children’s novel The Wonderful Wizard of Oz.
I’ve always been wondering, what exactly is this so called “emerald city” and why did Bellamy mention it? Well, maybe now we know why.
38 years ago, the Rocks Pirates attacked several World Nobles and their slaves on a island known as God Valley. Garp and Roger worked together to defeat the crew. This event, in which Rocks lost his life, is known as the “God Valley Incident”.
After the incident, God Valley mysteriously vanished, leaving no trace of its existence behind and no longer showing up on maps of the world.
One thing I noticed is that God Valley’s silhouette is very identical to the Emerald City in The Wonderful Wizard of Oz.
Is God Valley the legendary metropolis mentioned by Bellamy?
