I personally don't think they can avoid being hunted by a god. They're way below his personal power level. Metanoia's followers and the vampires would be balanced out more, but no, they can't just blithely hide from a deity.

On the other hand, all that hunting will take time. He'll be distracted, but he'll find them. They aren't that good at cloaking themselves that a god won't get to them.
