"Congrats, everyone. This city has been purged. No casualties this time with only some people got minor injuries. You did well, Sunglasses."

The battle is over. And I congratulated everyone. With Sunglasses take the credit for leading everyone to victory.

"...It's also thanks to everyone here. If we had just half the strength of what we have right now, or even slightly lower than half, Panthero might not be as it is today. And we could still be a kingdom without having to be controlled by Varadis," Sunglasses said.

What is Panthero again? Oh, right. Rudy's previous kingdom. And he's the brother of the king, right? And that king now is a noble under Varadis Kingdom who is in charge of Panthero's territory right now.
