The Northern Capital of the planet Kajadir holds the entire planet's wealth, power, and defense technology. The royal family and the inhabitants of the Capital stay cozy and safe inside the immense protective dome, unharmed by the moon Obsidiate's invasion attacks. The poorer citizens of Kajadir's South are left outside and unprotected against the invasion, and all they can do is beg for the North's aid. They're defenseless, that is, until they attempt to overthrow the North altogether through trickery, in the guise of a "peaceful wedding".
