Seven thousand years ago, he saved a tribe in the Sento River Basin of Seimachi Island.
Five thousand years ago, he planted a tree in Ohara on the Western Sea.
Three thousand years ago, he built a ship in the Capital of Seven Waters.
Nine hundred years ago, he searched the world for meteorite iron and forged twelve swords, just to shatter the void.
In the end, he failed and fell asleep at the bottom of the endless sea.
Later, that tribe became a country called Alabasta; that tree was called the Tree of Omniscience, that ship was Pluto who shocked the world; and the twelve divine swords were the twelve supreme sharp knives...
In this world, all the legends are related to him, but there is no legend about him.
He is Muchen, the blank that has been erased for a hundred years.
