Karyk removed his disguise, trying to prove that he wasn't an Elzerian. By now, he was convinced that she wasn't fond of Elzeria, which made it safe for him to reveal himself.
For him, the enemy of his enemy was a friend. Moreover, it was a friend who wasn't weak either. He needed a force in Elzeria to stop the invasion, and he could see the first step of gathering that force right before his eyes.
Every year, the Beasts attacked the Border City. They couldn't pass through the border defences, but even then, they caused a great loss of life. And that was when the strongest beasts hadn't even attacked the Border City.
Since he had taken control over the Border City now, if he could turn them to his side, it was highly beneficial. The City didn't need to worry about the attack from the beasts, which gave them time to develop. And secondly, he could support these people, using them against Elzeria.
