You have to marry Elena.

The palace chiefs and other important personalities in the kingdom called a meeting with their new king, king Arthur. The meeting was mainly to speak to him about the need to make haste and get married so his kingdom could have a Luna. Arthur however, had no idea that was what the meeting was about. He attended the meeting anyway, thinking it was about one of the things that concerned the land that they were there to speak to him about.

"My king," one of the chiefs started. "We're honoured to have you here today. We're glad you honoured our invitation to the meeting."

"Who am I not to honour it?" Arthur replied him.

"Thank you, your highness." Another one started. "The main reason we're here today is not about us, but about you."

"Me?" Arthur asked, placing his hand on his chest. "Is everything okay?"

"Yes. Everything is totally fine, my lord. But for things to continue to remain fine, that was why we called this meeting."
