Hocha

Gram was one of the archaeologists of Ohara.

History
For the penalty of studying and deciphering the forbidden Poneglyph, the World Government declared the Oharan Clan as "demons" for attempting to destroying the world, and had Spandine set the Buster Call on the island. Gram died in the island's destruction when the Tree of Knowledge burned down with him inside trying to save as many books as he could.
