In the great DC multiverse this has been designated Earth 33. Things may not be the way they are in other parallel timelines. The wards can effect what happens in this reality, nothing is set in stone.
Villains in other versions of earth might turn out to be heroes here and the heroes of other earths may turn out to be the darkest of all. There is no telling what will happen and who will rise and who will fall. Each earth in the multiverse is unique inspiring and terrifying in its own way.
