The Disaster occurs when the grigori succumb to lust, and led by their chief Azaz'el, conspire against God. The majority of the grigori sign a statement of refusal to obey God's wishes and take wives from among the human women of Earth, to whom they teach forbidden knowledge and the secrets of Heaven.
The grigori's wives give birth to nephilim children, half-human half-celestial monsters who consume all and everything to satisfy their immense appetites. Dominic tries the grigori and finds them guilty; the Seraphim Council votes to cast them out of Heaven. The War begins in earnest as angels and demons do battle across Earth, causing immense disturbances to the Symphony and slaughtering many, many humans.
