Tbh I think it's the fact that these Princes have Zahard's blood + the rings that makes them his greatest weaknesses.

Think about it: why aren't the Princesses of Zahard allowed to fall in love or marry? That's because Zahard doesn't want his power to go to those that he hasn't approved (hasn't gone through the special blood ritual and thus can't be controlled by him). Assuming that the Princes can't be controlled by Zahard (as they actually have the power that they aren't supposed to have because they have his blood unlike the Princesses), if these Princes were ever to go and have children, they could potentially create an army that has the strength/power of Zahard against him. With his power + the rings that are part of the key to the 135th floor, these kids could be the ones that overthrow him.
