Graviton is a supposed deity in Final Fantasy Blackmoon Prophecy II that has acquired an underground following. The Church of Graviton, which is headquartered in the town of Branch, is devoted to believing in Graviton to a borderline fanatical degree.
According to the Church of Graviton, their deity resembles a man who stands as high as the tallest castles and wields an adamantium hammer capable of sinking lands.
Despite the supposed deity being associated with violent tremors that have sunk lands and killed many, the Church of Graviton insists that their god is benevolent and loving.
Theories of Graviton emerged shortly after the Light Warriors emerged victorious over Lord Zeul and Malacore a century ago. When quakes led to parts of land sinking into the sea, researchers attributed it to the after effects of the Great Cataclysm. Religious individuals instead believed that it was the work of a gravity god that they took to calling him "Graviton". They took it upon themselves to preach that Graviton was an ancient god who was wishing to reshape the world into its original shape, prior to when the worlds were even merged. The Church claims that lands which have sunk were "tainted" and were not of Gaia. They are also adamant that Espers, not originally inhabitants of Gaia, have demonstrated that they are also a taint which must be removed by their war against humankind.
The Church of Graviton believes that their deity resides in the Miasma Stream where he strikes "evil and gnarled roots" with his adamantium hammer and sinks the lands that are said to be tainted.
