Arthur had to admit that such a notion would help them immensely, and Night would not be a part of the rebels, only reporting back to him. Although Lyle might not like it, this served Arthur's interests. However, there is one issue.
"We planned on striking the emperor once the executions happen, so freeing the prisoners is not going to help us," objected Arthur. "Although it would be risky, the executions must happen so that we take down the emperor."
"Can you even do that?" frowned Haro as she interjected. "I have seen your strength, but that's far from enough to take down an empire."
Arthur knew that she was right. His current strength is lacking, so even if he took down the emperor, the empyrean-rank ancestor would still pose a problem. Although he had no evidence of their existence, Arthur had to assume the worst-case scenario.
