Birkans

Bilkans (assumed name), are the race that came orginally from Bilka.

Appearance
Like Skypieans and Shandians, they have wings on their back. What seperates them from the other two races is that their wings face downwards. Their race was introduced with Enel and his Priests, but never identified until Enel's mini-series. One odd thing about their race is that many of them feature goat-like facial features such as floppy ears and horns. This was also seen in Enel's mini-series on an image that represented the three races of the Sky Islands, where an ancient drawing depicted a race with the same wings. Another member of their race is Urouge, a pirate in the blue seas.

History
Their known history is that they were one of three races that once lived on the Moon and aided in the creatation of the Spaceys. When resources on the moon dried up, they along with the Shandorians (ancestors of the Shandians) and the Skypieans left the moon and the Spaceys behind.

At some point in history, the three races became seperated from each other and fell into the individaul races that are seen in the current storyline of One Piece. They also appeared to "forget" their origins, although the moon, known to them as the "Fairy Vearth" remained a folk tale amongst their people, believing it to be a place of dreams.

Eventually, Enel came along and, using his Devil Fruit powers of the Goro Goro no Mi, destroyed their homeland of Bilka. He took over Skypiea and made himself God there.
