It was a valid question.
Considering that the evaluation was tied directly to the Cavity, if it was in any kind of peril, High Lord Rashal would be done for good. He would gain a bad evaluation from the evaluator, and the Cavity would be handed to someone else.
And that's precisely what High Lord Ursa wanted.
But there's a problem with that.
"Yes, attacking the Cavity would seal High Lord Rashal's fate—but it's not that easy to deal damage to it," Rex answered, giving Davina a piece of his mind. "It's guarded by countless Pale Defenders, and it is also very close to Larta City. If it was attacked, the responders would arrive quickly, making it a bad target to attack.
"Assuming that there's even someone from the God Realm who could even enter it," He added.
It was true that Rex arrived in the God Realm through the Cavity.
