In their self-indulgent realm, the gods know no suffering until the end of their days. Compassion is the only portal through which they can escape the self and its eventual demise, but without suffering, compassion cannot be recognized. So, they go in search of compassion in the human domain where happiness and sorrow abound. There, they genetically engineer a superior humanoid race and are soon distracted by the delight they find in the daughters of men. The gods are the extraterrestrial visitors of our collective memory.
Tormented by envy, the Asuras are warlike demigods that follow the gods into the human domain. They become the demons who initiate our concept of evil.
