Unogonduria

Unogonduria is a nation, spanning over the entirety of a hidden continent on another plane on existence. The "barrier" is magical and nature, and rarely lets anyone in. It is fully undetectable via any satellites from space or other methods of photography, and in its (the Unogondurian continent) place there appears, and is, the rest of the Pacific Ocean we all know and love. It is unknown who placed this barrier - was it aliens? Was it God? Was it a myriad of gods? Nobody knows, except the Creator Himself.
