Iwa Clan

Iwa Clan
The Iwa clan was one of the first clans to specialize in Earth Style ninjutsu. It was rumored that the clan's founder once met the Sage of Six Paths. Shortly before the First Great Shinobi War the Iwa clan hid themselves away to avoid the conflict. They had little contact with the outside world for the next decade, then vanished completely.

Two years before the Nine-Tails attacked the Hidden Leaf Village, young Hãdo Iwa was located near the Hidden Leaf Village. With no knowledge of where he came from or who he was, the people of the Hidden Leaf, most notably Minato Namikaze, brought him into the village. Hãdo was raised in an orphanage within the village. Several weeks before the Nine-Tails attack, Minato spotted Hãdo crate a diamond out of thin air. After extensive research, Minato discovered that Hãdo must have been of Iwa blood. There was no explanation as to how this was possible, as the Iwa clan had supposedly died out nearly a century before. Minato decided to keep the information to himself and carried his discovery to the grave.
