billions of angel years ago, God, the divine entity, created the universe based on the principles of chess, with each entity assigned a piece value. God created angelkind to balance the universe, but discord arose when Lilith, endowed with vast knowledge after consuming forbidden fruit, rebelled against submission to Adam. She seduced Lucifer, and together they incited a rebellion, leading to the fall of angels and a celestial battle. God, fearing defeat, empowered Saint Michael as the God Eater to vanquish Lucifer and his followers. Lilith and Lucifer were imprisoned, and the fallen angels were cast to Earth, cursed with hardships. Redemption lies in repentance, offering a chance to ascend once more.
