Master of the Future, it’s quite clear that Ash is aware of Cowl’s ambitions, and that is to be God, not merely a God.
I have posited that the date of creation of the White God has yet to occur, but it will be due to the sheer weight of humanitys belief willing him into existence around a foci, maybe Uriel, maybe Lucifer, maybe an Outsider, but maybe both Cowl and Drakul think they have a shot at it. Once created God is not bound by linear time and will exist at all points and at all times in the multiverse as the pre-eminent power.
Cowl has outlined his plan to become god to his dog.
