The Shield & The Queen

After king aultrcay, the king of melromarc, summoned all four cardinal heroes during an international assembly of all the nations of the world. It shocked every single one of them including the queen herself who is the true ruler of melromarc. All nations of the world was just about to declare war on melromarc especially the kingdom of siltvelt who is the exact opposite and the main enemy of melromarc until the queen has to go to every single nation to decrease their rage.

The queen had to go to every nation of the entire world to create a temporary peace treaty using her diplomatic skills on them. However, the kingdom of siltvelt cannot be persuade by the queen and has no interest of creating peace treaty between the two kingdoms. Thus, it means they want total war.

Once the queen realized all hopes are lost on creating a peace agreement with the kingdom of siltvelt. She thought of an idea that will make siltvelt not declare war on them. She leaves siltvelt as soon as possible by encountering a few attempts of assassination.

What is this idea of the queen? What's on her mind? And what is the involvement of our boy naofumi over here? What do you think?
