The Idol is a large sword of great power revered by the people of Garlan, who are themselves hailed as great swordsmen. It is said that the sword cannot be wielded by anyone but the greatest swordsman in the world.
The sword is wielded by Melfice once he absorbs the Horns of Valmar. He uses it to perform terrible deeds until he is struck down by his brother, Ryudo and the curse is lifted from his body. After his death, the sword is used to mark his grave in Garlan.
