I think the that the void realm is under strict control of that woman and that's may be because of the power of faith or the great number of its followers that give her alot of power so she can role the void realm and I think the same thing will go with the spirit realm even lady sphinx couldn't enter it beacuse of that rule or may be the supreme rules of the universe. and that's just my thinking may be right or may be wrong
