The Celtic scholar Peter Ellis notes, “Irish epic contains many episodes of the struggle between the Children of Domnu, representing darkness and evil, and the Children of Danu, representing light and good. Moreover, the Children of Domnu are never completely overcome or eradicated from the world. Symbolically, they are the world. The conflict is between the ‘waters of heaven’ and the ‘world.'” The same thing could be said of the Vedic wars of Devas and Danavas or the Puranic/Brahmana wars of Devas and Asuras.
