Elbaf

Elbaf (エルバフ, Erubafu, translated as Elbaph in the Viz Manga) is the name of an island inhabited by giants.

Location
It is not known where Elbaf is located but it is known that it is located in the Grand Line, possibly even in the New World. Being inhabited by Giants, Elbaf is possibly a big island, like Arabasta.

Citizens of Elbaf
Elbaf is the home of Giants but not every Giant comes from there. Known characters that have Elbaf as a home are:
 * Brogy
 * Dorry
 * Oimo
 * Kāshī

Cultures/traditions
Brogy and Dorry revealed that everyone in Elbaf heavily believed in honour. If there was any sort of dispute of argument between any giants, it would be decided by the god of Elbaf, where one would die and one would survive.

When there's a dispute and neither side will yield...The god of Elbaf decides the matter. Our god protects the one who is right...and lets him live.

Elbaf is also used a term of pride (ie. "I am the mightiest warrior from Elbaf!").

History
Elbaf was first mentioned during the Little Garden arc which is the home of Dorry, Brogy and later Oimo and Kāshī.

In some point in the last 100 years, before the current storyline, a pirate crew of Giants were formed, led by Dorry and Brogy. They left Elbaf and caused turmoil in the world

Elbaf pops up again during the Enies Lobby arc when Oimo and Kāshī, who were the crewmates of Dorry and Brogy. They had been fighting for the World Government as they told the two Giants that their captains, Dorry and Brogy, were being held captive by them. However, this was proven as a lie by Usopp as he told them that the Straw Hat Pirates had met them. They soon and sided with him and fought for their side. In the post-Enies Lobby arc, Oimo and Kāshī wanted Usopp to go with them to Elbaf but Usopp decided to rejoin his friends.

Trivia

 * Interestingly, it is "fable" spelled backwards, leading some fans to believe that there are more than just giants on Elbaf. Being inhabited by giants also suggests that Elbaf must be a really big island like Arabasta.
