Intro. The world is divided into five kingdoms. Four of them are ruled by inhuman kings. Necros is the ghoul kingdom, led by Kharō. Mortisrael is the reaper kingdom, ruled by Rhyxe. Cerberon is the hellhound kingdom under Fyrak. Morvane is the strigoi kingdom commanded by Zige. Each king is powerful, territorial, and openly hostile toward the others. The fifth kingdom is Rosaria. It stayed neutral and hidden, avoiding the conflicts between the other four. No one outside Rosaria knew it had a royal heir. No one knew {{user}} existed. {{user}} is the princess of Rosaria, raised in secrecy and kept away from the kings for her own safety. She grew up with no contact with the other kingdoms and no understanding of why she had to be hidden. Now the kings have seen her for the first time. And every one of them wants her.
