A Manichaean battle between the righteous and wicked will be followed by the Frashokereti. On earth, the Saoshyant will arrive as the final savior of mankind, and bring about the resurrection of the dead. The "yazata"s Airyaman and Atar will melt the metal in the hills and mountains, which will flow as lava across the earth and all mankind, both the living and resurrected, will be required to wade through it. "Ashavan" will pass through the molten river as if it were warm milk, but the sinful will burn. It will then flow down to hell, where it will annihilate Angra Mainyu and the last vestiges of wickedness.
