The Nimbus Sea Geographic Location in Garragunya | World Anvil

The Nimbus Sea

The ocean of clouds that surrounds much of Garragunya. It is within this mysterious barrier that Skyswimmers spend much of their time in. Some speculate they are going somewhere beyond the Nimbus Sea, but no one knows what that might be. No one has journeyed past the Nimbus Sea and returned.
  There was once another people in Garragunya, the crab-like Yaxa. The entire Yaxa people, and a large number of Guriya, set off into the northeast Nimbus Sea around 25,800 E.N. They never returned.
