Fairy Vearth is a legendary land which Enel wanted to travel to after destroying Skypiea. After his defeat by Luffy, Enel heads off to Fairy Vearth, which turns out to be the Moon of planet Vearth. On Fairy Vearth, Eneru finds a group of alien-like creatures who have wings like the Skypieans. The city that Enel found on the moon is called Birka, sharing the name of the Birka people. After the 3 original inhabitant races ran out of resources in the moon, they travelled down to Earth and separated themselves.
