After making a deal with Roy and filling him in on the first stage of their plan, he offered them a place to stay in the palace, it was necessary given that the day of the attack was tomorrow.
Festus and the two young knights didn't want to spend the night in the palace but the desperation in Roy's voice as he spoke to them was the reason why they had decided to stay.
Sure he was a bad and greedy king but this wasn't all about him and they have to do everything possible to make sure that Asaka is safe.
Roy had ordered two of the maids in the palace to lead to one of the empty rooms in the palace which had beds for the three of them.
After leading them to the room, the maids asked them if they needed anything which they replied no to.
"I just pray this works," Jude said sitting down on one of the beds.
"It will work," Carl said.
"And then you can finally be free," Jude said, turning to Festus with a smile as the light wizard responded with a nod.
