Demons of Ohara

The Oharan Clan was a group of scholars who resided in the island of Ohara located in the West Blue. They studied in a huge library tree called the Tree of Knowledge. They were trying to research the 100 years void that the World Government are trying to keep a secret from the world. They are called "Demons of Ohara" by the World Government for breaking the worldwide law.

Demons of Ohara
Demons of Ohara is a political term coined by the World Government to refer the Oharan Clan. Because researching on poneglyphs was illegal, the World Government ordered the bombardment on Ohara. They used the "Demons of Ohara" as an negative term for breaking the law. The world was led into thinking that Ohara was seeking the Ancient Weapons, thus Ohara's reputation was ruined.

This term led to a hard life for Robin, having to carry the term like a curse; hated by the world, thinking she wants to destroy them. She has gone as far as being branded as a "Demon Child" by the Government.

History
800 years ago at the end of the 100 years void, the World Government forbade the research of Poneglyph. Scholars who dared to refuse this law were killed. The numbers of deaths were countless as stars.

Ohara was one of the archaeologist clan that managed to evade the eyes of the World Government. It's not known how long they have been around. They have boasted that the Tree of Knowledge was over 5,000 years old. They may have researched the Poneglyph for hundreds of years.

With the only exception of Nico Robin, they were all killed in Ohara Buster Call.

Notable people
Aside from Robin, Olvia, and Clover, seven of the twenty scholars were named.
