Structural lore — what Oda has confirmed about this. Mysteries (unsolved questions) live in
Vault/Threads/; this is what the world IS.
What we know
- Ch. 237 (pages 5–8): At the top of the Knock-Up Stream there is a sea of clouds above the Blue Sea — the “Sky Ocean” (White-White Sea). A ship can sail on its surface.
- Ch. 237 (pages 8–10): The cloud sea is two-layered — a sailable surface, and a deeper “fluffy” layer with almost no resistance through which a body sinks (it is bottomless white; Usopp nearly drowns in cloud). Nico Robin asks whether the ocean even has a bottom.
- Ch. 237 (page 8): The arrival level is the “middle level of the Emperor Cloud.” The Log Pose still points up, indicating the destination (Skypiea) is higher still.
Chronology / structure
(Geographic: surface cloud = sailable; deeper “fluffy” cloud = bottomless, near-zero resistance. Altitude marker = middle level of the Emperor Cloud.)
